UPS Operation

Use the following procedure to reinstall the PPU and transfer the critical load from Maintenance Bypass (AC Line operation) to the PPU:

1.Reconnect the battery cabinet to the battery connector on the PPU rear panel.

2.Switch the circuit breaker on all battery cabinets to the ON ( ) position.

3.Confirm the correct UPS output voltage is selected according to the PPDM model:

PPDM Model Number

208: 120/208 Hardwired

Set to 208V for 120/208V PPDM output

 

Set to 220V for 127/220V PPDM output (60-Hz units only)

Set to 220V for 110/220V PPDM output

 

240: 120/240 L6-30R

Set to 230V for 115/230V PPDM output

 

Set to 240V for 120/240V PPDM output

 

240:120/240 L14-30R

240:120/240E Hardwired

*The UPS output voltage should match local voltages.

Using a screwdriver, turn the switch to the corresponding position of the output voltage required (see Figure 25). The output voltage is factory-set to 220V.

C A U T I O N

Do not turn the Voltage Selector switch while the UPS is operating (see “Changing the Output Voltage” on page 53). Changing the output voltage while the UPS is operating may cause an emergency power-off.
