UPS Start-up and Shutdown

Attention: The first time the UPS is started-up, the utility must be connected to the mains (no cold-start).
This is to prevent turning on the UPS by mistake during transportation.
IMPORTANT: Switch off the connected loads before turning on the UPS. Then switch on the loads one by
one after the UPS is turned on. Switch off all of the connected loads before turning off the UPS.
WARNING!

UPS start-up

With mains supply
1. Check that all cables are connected correctly and well-fixed mechanically.
2. Measure the power supply current and voltage to ensure it is energized.
3. Connect the mains power to the UPS.
4. Check that the battery cabinet breaker is on position ON (when using external battery cabinets).
5. Set input breakers (M1 and M2) to position-on. The fans start running, the UPS will perform a self-
test and will then display the status menu.
6. Press the power-on button for more than 1s, the alarm buzzer sounds and the UPS start-up takes
place.
7. After a few seconds, the UPS goes to online-mode. If the mains power is abnormal, the UPS will
transfer to battery-mode without interruption of the UPS's output power.
Cold Start (UPS start-up without mains supply)
1. Check that all cables are connected correctly and well-fixed mechanically.
2. Check that the battery cabinet breaker is on position ON (when using external battery cabinets).
3. Press the power-on button. The UPS will perform a self-test and display the status screen.
4. Press the power-on button continuously for more than 1s, the alarm buzzer sounds and the UPS
start-up takes place.
5. After a few seconds, the UPS transfers to battery-mode. When the UPS is again supplied with power
from the mains, the UPS transfers to online-mode without interruption in the output of the UPS.
5.3.2

UPS Shutdown

With mains supply
1. If the UPS is working on bypass-mode, go to step 3.
2. If the UPS is on online-mode, press the power-on button continuously for more than 3s. The alarm
buzzer will sound and the UPS will transfer to bypass-mode. Note: the output is still energized.
3. Disconnect the UPS from the mains power supply through the output breaker. A few seconds later
the display will shut down and the output voltage will be removed from the UPS output terminal.
In case the bypass has been disabled through the Settings menu, press the power-on button for more
than 3s to shutdown the UPS. The unit will change from online to stand-by-mode. Then, simply
disconnect the input power cable and a few seconds later the display will shutdown.
Without mains supply
1. To power off the UPS, press the power on/off button continuously for more than 3s. The alarm
buzzer will sound for 3s and the output power will be immediately cut-off.
2. After a few seconds, the display will shut down and the output voltage will be removed from the UPS
output terminal.
