Switching off the UPS
Caution: All power to the load will be removed when you follow this procedure.
To switch off the UPS:
1. On the front panel (see Figure 4 on page 17), press OFF to place the unit in bypass mode.
2. When prompted by the LCD, press Ent to confirm your action. The Bypass LED turns on and the
Inverter LED turns off.
3. On the rear panel, turn off the unit main breaker. After a few seconds the unit shuts down (the fan
stops and LCD and LEDs turn off).
Swapping out a UPS on a live system
E200 series units are fitted with a bypass box that allows you to swap a UPS without the need to do any
wiring.
Note: Always use a PH2 Phillips screwdriver and not a pozidrive (PZ) screwdriver.
To exchange a UPS while maintaining the load:
1. On the front panel, press OFF to switch the unit to bypass mode.
2. When prompted by the LCD, press Ent to confirm your action. The Bypass LED turns on and the
Inverter LED turns off.
3. Access the rear panel and remove the screw that holds the maintenance breaker cover in place. It is
located just above the input breaker.
4. Turn on the maintenance breaker.
5. Turn off the UPS main breaker. At this point power flows into and out of the bypass box only.
6. Remove the four screws that hold the bypass box in place and extract the box from the UPS.
7. Replace the UPS.
8. Slide the bypass box into the new UPS.
9. Turn on the
new UPS’s main breaker.
10. Ensure that the Mains and Bypass LEDs are illuminated. This indicates that the UPS is working
correctly.
11. Turn off the maintenance breaker and fasten its protective cover in place. After a few seconds the
UPS automatically switches to on-line mode.
