2.3 Connecting the protected equipment
A Pulsar Evolution 1500 tower UPS has been used below to illustrate the instructions. The principle is the same for all the other tower and rack models. Check that the indications on the rating plate on the back of the UPS correspond to your AC-power system and to the actual electrical consumption of all the equipment to be connected to the UPS. 1 - Remove the power cord supplying the equipment to be protected. 2 - Connect the power cord (1) just removed from the equipment to the AC-power socket 8 , and then to the AC-power wall outlet. 3 - Connect the protected equipment to the UPS using the two cords 20. Connect priority loads to the two standard outlets 5 and any non-priority loads to the two programmable outlets 6 (1 and 2). If the UPS is connected to a computer running MGE communications software, it is possible to program the interruption of power to the programmable outlets 6 during operation on battery power, thus reserving backup power for the priority loads. 4 - Lock the connections using the securing system 26 (for rack models only).

As soon as the UPS is energised, the battery begins charging. Eight hours are required to charge to the full rated backup time.
(1) Make sure the cord has the following characteristics: 250 V, 10 A, cross-sectional area 1 mm2, type HO5.

2.6 Installation of the communications-card option
Restricted-access slot for the communications card 1 - Remove the slot cover 4 secured by two screws. 2 - Insert the card in the slot. 3 - Secure the cover with the two screws.
It is not necessary to shut down the UPS to install the communications card. This operation must be carried out by qualified personnel.

- Page 17

3. Operation

3.1 Start-up

Press the ON / OFF button 10. The buzzer beeps and all the LEDs come ON. The buzzer beeps twice during the self-test, then button 10 remains ON, indicating that the outlets are supplied with power. - AC power is present: Only button 10 is ON. The protected equipment is supplied by the AC-power source. - AC power is absent: Button 10 and LED 11 are ON. The protected equipment is supplied by the UPS, operating on battery power. All the connected equipment is supplied with power.
If button 10 or LED 11 are not ON or if LED 12 is ON, there is a fault (see section 4.1). Note: The battery is charged as soon as the UPS is connected to the AC-power source, even if button 10 is in the OFF position.
3.2 Shift to booster or fader mode (during voltage variations in the AC-input power)
The booster and fader functions maintain the output voltage supplied by the UPS within close tolerances around the rated value even if significant voltage variations occur in the AC-input power. This avoids calling on battery power. The values defining the voltage range may be set using the UPS Driver software. During operation in booster or fader mode, LED 16 is ON, signalling a significant voltage variation in the AC-input power.

Page 18 - 34007117EN/AB

3.3 Operation on battery power (following failure of AC-input power)
Transfer to battery power
The AC-input power is out of tolerances, LED 11 goes ON. During operation on battery power, the buzzer beeps every ten seconds. The equipment connected to the UPS is supplied by the battery.
Threshold for the low-battery warning
When the threshold is reached, the buzzer beeps every three seconds. The low-battery warning threshold can be set by the user, with the UPS Driver software. There is very little remaining battery backup time. Close all applications because UPS automatic shutdown is imminent. When the battery reaches the end of its backup time, the UPS shuts down and all the LEDs go OFF.
The equipment is no longer supplied with power.
The UPS automatically restarts when power returns. If the UPS does not restart, check that the automatic restart when power returns function has not been disabled (see section 3.4 Personalisation).

- Page 19

3.4 Personalisation (optional)

Function

Personalisation parameters can be set and modified using the UPS Driver software installed on a computer that is connected to the UPS (see section 2.4 Connection to the RS232 communications port). Check that the RScommunications cable is connected. UPS Driver installation: 1 - Insert the Solution-Pac CD-ROM containing the UPS Driver software in the drive of a PC running Windows. 2 - Open the Windows File manager or Explorer and select the CD-ROM drive. 3 - Double-click "\Emb\Evolutio\Config\upsdriv.exe".
