Feature: Active-Front Technology
Traditional input THD filters are no longer needed with this UPS product. The build-in advanced rectifier technology of UPS modules provides perfect sinusoidal input power quality at 0.99 input power factor with harmonic content less than 5% THD(i). This leads to more reliable total system operation and savings in generator and transformer sizing as losses in the windings are minimised.
Due to the active front rectifier, the UPS is comparable to a clean resistor load from the mains perspective. Thus, the high input power factor provides minimised cabling and fusing costs due to no reactive power consumption. The low harmonic currents are due to high input power factor and provide the benefits:
No additional losses in wires and cables No extra heating of transformers and generators with shortened service life No false circuit breaker tripping and malfunction No erratic operation of computers, telecommunication, monitors, electronic test equipment etc. No Resonance with power factor correction capacitors
Feature: Advanced Battery Management (ABM)
The ABM monitors the status of the battery and charges it only when the battery needs charging. This is the key to long battery life with the ABM due to low generation of corrosion inside the battery. It also monitors that the load never crashes because of bad or defected battery. The main cause for corrosion is current flowing through battery. The more current going through battery, the shorter the battery life. Current flows through battery when it is discharged or charged. There is very little that can be done for discharging, because it depends on number of power outages in utility line. The ABM is very valuable feature since most of the time battery does not need any charging. The charging is controlled and initiated on the following occasions: - When turning the unit on - After 18 days without charging - If the open cell voltage decreases below predetermined voltage level Hence, the function of ABM system is to prolong the battery life considerably compared to traditional system that uses float-charging technology. This means that there is no current going through batteries all the time and causing corrosion. In a traditional online UPS the inverter also causes ripple-current to be fed to batteries causing corrosion.
Feature: Hot Sync technology

The UPS product features U.S. #5,745,365 patented paralelling technology that provides N+X redundancy without introducing a single-point-of-failure. The products utilising the Hot Sync are completely autonomous and the only thing common among them is the critical output power bus. The Hot Sync is 100% mathematical firmware that makes it more reliable than traditional paralleling techniques. Because the solution is implemented intrinsically, and Hot Sync is always active, the UPS modules do not know whether or not they are even in parallel.
A parallel UPS system means the linking together of two or more UPS units in parallel so that in the unlikely event one fails the other can automatically take up the load. Traditionally a parallel redundancy configuration is achieved by having a random or fixed master-slave relationship among the UPS units. This master logic gives out individual commands to all the slaves units. Unfortunately this can lead to a single-point-of-failure for the whole system because if the master logic or communication to slaves fails, and causes the whole UPS system to be in trouble. The Hot Sync technology was developed to allow parallel capacity system and to maintain the highest system availability. An industry leading paralleling technology in its own right, the patented Hot Sync enables you to set up a parallel redundant system giving you 100% conditioned power at all times. Its unique digital design eliminates the system level single point of failure inherent in traditional parallel UPS modules, and exponentially increases the reliability of the overall system. Hot Sync allows up to four UPS units to cover the same load in parallel and redundant configuration. No vulnerable master logic is needed in this patented design. It provides automatic load sharing and module level redundancy with nothing other than the power connecting the Hot Sync version of UPS modules.
Basic system configuration
The following basic UPS system configurations are available:
A single UPS system: - UPS cabinet with 0-4 battery strings - Runtime with internal batteries - External battery cabinet - LCD display for easy configuration A parallel UPS system - Up to four units can be paralled

Maintenance bypass switch
The maintenance bypass switch (MBS) shall be mounted in the bottom of the UPS cabinet. It can be ordered factory installed.
External battery cabinet option
Its recommended to install external battery cabinet(s) next to the UPS unit. The external battery can be placed on either side of the UPS unit, but it is recommended to instal on left hand side. Check before the installation that the battery voltage values in the type plate of the UPS and external battery cabinets are the same. The cables are delivered with the external battery cabinet.
The UPS contains high DC voltages. A qualified person must do the connections between the UPS and the external battery cabinet(s). The battery cabinet is connected electrically in parallel with the internal batteries of the UPS.
If available, the internal battery has to be disconnected first because the external battery terminals may be hazardous due to parallel battery strings.

Battery racks

External battery racks shall be sized to take the voltage drop in the cable into account. To obtain support and help contact the local office or agent authorised by the manufacturer.
6. Electrical installation
The customer has to supply the wiring to connect the UPS to the local power source. The electrical installation procedure is described in the following text. The installation inspection and initial start up of the UPS and extra battery cabinet must be carried out by a qualified service personnel such as a licensed service engineer from the manufacturer or from an agent authorised by the manufacturer.
Physical injury or death may follow, or damage may occur to the UPS, or the load equipment if these instructions are ignored.
Figure 6 Location of the power terminals. S1:Service Bypass Switch; S2:Static Bypass Input Switch; S3:UPS Output Switch. Disconnect all internal battery strings before operating with the terminal X4.
The UPS unit has the following power connections:
Three-phase (L1, L2, L3), Neutral (N) and protective earth (PE) connection for the rectifier input Three-phase (L1, L2, L3), Neutral (N) and protective earth (PE) connection for the bypass input (N is common for rectifier and bypass inputs) Three-phase (L1, L2, L3), Neutral (N) and protective earth (PE) connection for the load output Plus (+), minus (-) and protective earth (PE) connection for the external batteries

The rectifier requires a Neutral to operate. Its connected internally from the bypass terminal to the rectifier, see wiring diagram.
Power cables and protective fuses
Always use copper cable types to fit terminals with approx. 1.5 Nm torque for different load currents. The Cu cable sizing is based on multi-core cables laid in conduits/trunkings on the wall or on the floor (installation procedure C), ambient temperature 25C, PVC insulation, surface temperature up to 70C. Cables of several UPS can be installed in parallel to each other. Standards SFS 6000-5-52 (2002) and IEC 60364-5-52 (2001-08) Electrical installations of buildings with normal 1.7 x Neutral conductor rating for IT loads are used as a sizing guide. For any other conditions, size the cables according to the local safety regulations regarding installation environment, appropriate voltage and currents of the UPS. Fuses are sized according to local safety regulations, appropriate input voltage and the rated current of the UPS. Therefore, protect the input and bypass cables with gG (gL) fuses or B-C-D type of circuit breakers against overload and short-circuit. Contact the manufacturers authorised agent or the local office for assistance at fuse and cable sizing. Refer to the recommended cable and fuse ratings in the below table.

Wiring procedure

The power cable terminals are located in the bottom of the UPS unit. The service personnel is responsible for the correct electrical installation.
The installation procedure:
1. Remove the cover plate(s) at the bottom or back of the UPS cabinet to make a route for input and output wires. Refer to the dimensional drawing for the correct location at the back of the unit. Route the cables through the hole at the bottom or back of the unit. If more installation space is needed the lowest battery shelf can be removed temporarily. Connect the conductors of the rectifier and bypass input cables to the proper terminals. Connect the conductors of the load cable to the proper terminals. Connect the conductors of an external battery cabinet cable to the external battery +, - and PE terminals. Check for the correct polarity. See also section External Battery Cabinet (EBC) installation procedure.

2. 3. 4. 5.

If available, the internal battery has to be disconnected first because the external battery terminals are hazardous due to the parallel battery string.
The IEC/EN 62040-1 safety instructions require the fitting by the user of a warning label on all primary power isolators installed remote from the UPS area. The warning label for electrical maintenance personnel shall carry the following wording or equivalent: ISOLATE UNINTERRUBTIBLE POWER SUPPLY (UPS) BEFORE WORKING ON THIS CIRCUIT. A readily accessible disconnect device shall be incorporated in the building installation wiring as shown in diagrams.
Figure 7 Wiring diagram of UPS N-model with integral MBS.
Figure 8 Wiring diagram of UPS N-model.
External Battery Cabinet (EBC) installation procedure
The installation procedure is as follows: 1. 2. 3. 4. The External Battery Cabinet (EBC) is recommended to be placed to left hand side of the UPS unit. The required minimum distance for UPS unit and EBC is 10 millimeters, which is also required distance between two EBCs. Turn F1 battery breaker from the UPS unit to OFF position. Before connecting cables to the EBC disconnect one of the cables (+ or -) from each EBCs battery string and remove fuses from upper part of the cabinet. To be on the safe side, measure the voltage accross the terminals to be 0 (zero).
Turn F1 battery breaker from the UPS unit to OFF position and measure the voltage accross the terminals (X4) to be 0 (zero) before any operations with terminal X4.
5. 6. When all the EBCs are connected parallel, measure the voltage accross the terminals (X4) to be 0 (zero) and connect cables to terminal block X4 of the UPS unit. After installation place removed fuses to original position, reconnect disconnected battery strings, check that the removed plates on right positions and turn breaker F1 to ON position. Finally change the number of battery strings from User Settings. SETTINGS -> USER SETTINGS -> NUMBER OF BATTERY STRINGS.
7. Software and connectivity
The Software Suite CD-ROM that is bundled with the UPS contains software distributions and documentation in CD format. Furthermore, the comprehensive connectivity option portfolio includes Web/SNMP adapters for networked environments, Modem card for 24/7 remote monitoring, ModBus/Jbus card for building management system integration, relay interface cards for industrial and facilities use and RS-232 cards for serial communication to one or multiple computers.

Communication cables

It is recommended that the control cables and power cables be installed on separate trays. Where control cables will cross power cables make sure they are arranged at an angle as near to 90 degrees as possible. All control cables shall preferably be shielded. If the shield is grounded, this shall take place on only one end of the cable. The procedure for connecting the control cables is the following: 1. 2. Remove the door by opening locks and lifting the door away of its original position. Locate the control terminal or XSlot module where you want to install the communications cable.

EPO does not necessarily disconnect supply to load when unit is on internal or external bypass. Quaranteed disconnection of bypass supply has to be through a separate disconnect switch located in the supplying switchgear cabinet.
In order to have the UPS running again pins 1 and 2 of connector X52 have to be reconnected and the UPS started manually. The pins must be shorted in order to keep the UPS running. Maximum resistance is 10 ohm. The EPO shall not be galvanically connected to any mains connected circuits. Reinforced insulation to the mains is required. See also Start-up after EPO. If the use of normally open EPO operation is desired, the loop on X52 has to be retained and the normally open EPO switch connected to X12. Operation is as above.

Relay outputs

The UPS incorporates a programmable relay output with potential free contacts at X57 for remote alarm indications. It is rated for max. 30 VAC 1 A or 60 VDC 0,2 A nominal values. Additional (4) relay outputs can be obtained with the XSlot compatible AS/400 Relay Module. For more information, see the section Using relay outputs.
The relay contacts must not be directly connected to mains related circuits. Reinforced insulation to the mains is required.
Programmable signal inputs
The UPS incorporates two programmable inputs (X44, X45). Use of a non-polar (relay) control input is recommended. The pins must be shorted with maximum resistance of 10 ohm in order to activate the specific input.
Please note the polarity of the inputs as indicated in the external control connections if used with a polarity control.
The default and programmable settings for the signal inputs are a) b) Disable Bypass Operation If active the automatic transfer to the static bypass is prevented. Charger off If active the batteries charging is disabled. In case of mains power outage the discharge of batteries is supported. Remote ON/OFF If active the UPS output turns off regardless of mode of operation. Auxiliary power, fan, communications and rectifier/battery charger shall remain functional. Restart initiated immediately when inactive. Request Bypass If active the UPS transfers to bypass if bypass voltage, frequency and synchronisation are ok.

e) f) g) h) i) j) k)

Request Normal If active the UPS transfers to inverter operation if not prohibited by EPO or alarm condition. Force Bypass If active the UPS is forced to static bypass operation regardless of the bypass status. External Battery Breaker Status If active the UPS knows that the batteries are disconnected. Building alarm 1-6 These can be activated separately or at the same time with other building alarms. Not in use (default) Shutdown If active the UPS will shutdown immediately. Delayed Shutdown If active the UPS will shutdown after user configurable delay time. Restart initiated immediately when inactive. Normal/Bypass If active the UPS transfers to bypass if ok. If inactive the UPS transfers to inverter when possible.

Shutdown

The procedure to shutdown from LCD is following: 1. 2. 3. 4. 5. 6. 7. Push any key of the control panel to enable the functions of the LCD screen Select TURN UPS OFF from the LCD menu (see: Display Functions) Press and hold button for 5 sec. There shall be an indication sound during the hold. UPS will enter a stand-by mode and continues charging batteries with a cooling fan operational. Output is without the voltage in the stand-by mode. Press and hold button for 5 sec. There shall be an indication sound during the hold. UPS shall do a shutdown routine. Turn the battery breaker (F1) and input circuit breaker/switch (F2) to OFF position to finalise the shutdown procedure.
The behaviour is different if UPS is turned off from the programmable input or through communication cards. If battery and input circuit breakers are left ON, UPS will enter a stand-by mode and starts to charge batteries with a cooling fan operational. Output is without the voltage in the stand-by mode.

9. Maintenance

All operations inside the unit must be performed only by a service engineer from the manufacturer or from an agent, authorised by the manufacturer. The troubleshooting procedure gives simple remedial if a malfunction occurs in the UPS. The operator should start the trouble shooting if there is an active alarm indicated on the LCD screen. Service should be contacted if the active alarm is abnormal and displayed as a service code. Call service if you are not able to solve the problem. LCD display Overload Description The connected load needs more power than the UPS is rated to provide. The inverter or static bypass is supplying the excessive load level. Your batteries are detected to be faulty. The UPS is operating in stored energy mode. It will shut down soon due to low battery voltage. The UPS is operating in stored energy mode. High UPS temperature is detected. Action Shut down the least important load that is connected to the UPS. The UPS should switch back to normal operation once the load level is acceptable. Batteries should be replaced and you need to contact the local office or representative of the UPS manufacturer. Make controlled shutdown of the protected load immediately to prevent loss of data. Save your data and perform a controlled shutdown of your load. Check that fans are operational and ventilation holes are not blocked. Make sure the ambient temperature is not excessive

Table 6 Typical alarms displayed in the LCD screen of the UPS unit.
Regular service/intervals
The UPS requires very little maintenance if installed in an appropriate environment. In order to ensure maximum availability of the UPS, manufacturer recommends signing a proactive service agreement with a local authorised service provider. Maintenance Batteries change Batteries test Cooling fan change Interval ~ 3-5 years / service ~ 18 months / service ~ 5 years / service

Table 7 Routine maintenance intervals recommended by the manufacturer.

Batteries

The condition of the batteries is crucial for operation. The UPS will indicate by audible and visual alarms if the capacity of the battery bank has decreased. The UPS units are provided with the automatic battery test and ABM management function to continuously monitor the condition of the battery bank. Servicing of batteries should be performed or supervised by personnel knowledgeable about batteries and required precautions. When replacing batteries, replace with the same type and number of batteries.
Do not dispose of batteries in a fire. The batteries may explode. Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic.

Cooling fan

The cooling fan lifespan of the UPS unit is about operating hours. The actual lifespan depends on the environment and ambient temperature. Fan failure can be predicted by increasing noise from the fan bearings. The fan replacement is recommended once this symptom starts appearing. Do not use other than manufacturers specified spare parts.

LED Indicators

The UPS unit has (4) LEDs to indicate the status. Graphical sign LED Green Yellow 1 Yellow 2 Red Description UPS status is ok. UPS is in battery mode UPS is in bypass mode UPS has an active alarm Blinking when new alarm is not reset and still active. Note Blinking when a new notice message is active.
Table 8 Description of the LED indicators.
Maintenance bypass switch (MBS) operation
The maintenance bypass switch may be as standard or as optional in your system depending on the ordered configuration. The operation of the MBS is allowed for a trained person only who is familiar with the UPS behaviour and functions. The full UPS wiring diagram with a MBS switch is presented in the installation part of the manual. The MBS is located in the bottom of the UPS near power terminals
The MBS consist of three switches and failure to understand the correct sequence may drop the critical load.

Table 11 Recommended cabels and fuses for the wiring diagram
Protection fuses need to be used for load cabling if manufacturers SPM (or similar) not used.
Required parallel system wiring length should be in accordance with the following rule, as referenced to the diagram below to ensure approximately equal current sharing when in static bypass mode (see figure below): Total length of 1A + 1B = Total length of 2A + 2B = Total length of 3A + 3B = Total length of 4A + 4B
This rule has a tolerance of approximately 10% for the combined input and output wire lengths. If installing only two UPS modules (redundant), this requirement is no longer required as each UPS is capable of supporting the full bypass requirement. However, this would preclude future expansion. The recommended length of B cables is 2 m or more.
Figure 25 Bypass wiring diagram and cable length notes

Aux. MBS contacts

Position data connection between SPM and UPS should also be done before taking system in operation. Follow the procedure below to build up position data connection: 1. Remove the door from the UPS. 2. Connect the cables in UPSs programmable input terminal X44 or X45. 3. Connect communication cables to terminals 1 and 2 for UPS Module #1 and to terminals 3 and 4 for UPS Module #2 in the SPM.

If some settings are changed from User settings the same changes need to be done separately to all of the UPSs in the system.
Carry out the following procedure to each UPS you want to have in system. 1. Turn the battery and input circuit breakers to ON position. 2. UPS will enter a stand-by mode and starts to charge batteries with a cooling fan operational. Output is without the voltage in the stand-by mode. 3. Push any key of the control panel to enable the functions of the LCD screen. 4. Select unit number in parallel system: Unit #1, Unit #2, Unit #3 or Unit #4. Select: SETTINGS -> USER SETTINGS -> PARALLEL OPERATION SETTINGS -> PARALLEL UNIT NUMBER 5. Select minimum units to support load: 0-4. Select: SETTINGS -> USER SETTINGS -> PARALLEL OPERATION SETTINGS -> MINIMUM UNITS TO SUPPORT LOAD Do the following item (item 6) only for one UPS, which belongs to the system. 6. Return to main menu and select TURN SYSTEM ON. All the UPSs shall check their internal functions, synchronize to bypass and start to supply the load.
After the first start the load sharing of the system needs to be calibrated. Before starting the calibration the system needs to support some load.
7. Select: SETTINGS -> USER SETTINGS -> PARALLEL OPERATION SETTINGS -> START AUTO CALIBRATION
Operating system bypass switch
The system bypass switch is used to bypass the parallel system during maintenance or servicing. Maintenance bypass switch is located on the front panel of the optional SPM cabinet. using the switch does not cause any break in the output voltage, if the input voltage and
frequency are accepted and the system is synchronised to the input mains. SPM-30-2 and SPM-60-2
The parallel module includes a mechanical bypass switch S3 (Make-Before-Break type) and two maintenence switches S1 and S2 for disconnecting the outputs of UPS modules during maintenance or service. The maintenance bypass switch has the following positions:
I or UPS normal position, the load is supplied from the UPS modules. II or BYPASS position, the UPS modules are bypassed and the critical load is supplied from the system bypass power line.

SPM-30-4 and SPM-40-4

The parallel module includes a mechanical bypass switch S5 (Make-Before-Break type) and four maintenance switches S1, S2, S3, and S4 for disconnecting the outputs of UPS modules during maintenance or service. The maintenance bypass switch has the following positions: I or UPS normal position, the load is supplied from the UPS modules. I+II or UPS+BYPASS position, the load is supplied from UPS modules (internal bypass mode) and the system bypass in parallel. II or BYPASS position, the UPS modules are bypassed and the critical load is supplied from the system bypass power line. If the system bypass switch needs to be used it is recommended to check that the bypass input power is connected and present in the SPM cabinet. The swicth is used only on rare occasions and the procedure is following: 1. 2. 3. 4. Check that the bypass not available alarm is not active in the UPS modules. (Press menu button, choose UPS status display). Use LCD to turn UPS unit(s) on internal bypass mode. Select: CONTROL -> GO TO BYPASS MODE Verify the transfer before proceeding the next step. Turn the maintenance bypass switch to BYPASS position.

Warning

The use of the maintenance bypass switch will cause a break in the output voltage if the input voltage or frequency is not correct and the UPS system is not sychronised to mains.
Following procedure does returning to normal online mode: 1. 2. 3. 4. 5. 6. Make sure UPS modules have been started according to chapter Start-up procedure,. Check that UPS ON and BYPASS LEDs are lit in the front panel. Make sure service switches S1.S2/S4 in the SPM are in ON position. Turn the system bypass switch S3/S5 to UPS position. Use LCD to turn UPS unit(s) to normal mode. Select: CONTROL -> GO TO NORMAL MODE. Verify the transfer by checking that the yellow bypass LED is turned off.
