4.5UPS Sidecar Operation – Maintenance Bypass Configuration

4.5.1Using the UPS when a UPS Sidecar is Installed

NOTE Before starting the UPS with the UPS Sidecar, verify all installation tasks are complete and a preliminary startup has been performed by authorized service personnel. The preliminary startup verifies all electrical interconnections to confirm the installation was successful and the UPS operates properly.

1.Remove the screw securing the bottom of the UPS Sidecar front panel. Lift up the panel and remove.

2.Verify that the UPS Sidecar circuit breakers and switches are set as follows:

MBP

OPEN

MIS

CLOSED

 

 

BIB (if installed)

CLOSED

 

 

RIB (if installed)

CLOSED

 

 

3.Reinstall the UPS Sidecar front panel and secure with the screw at the bottom of the panel.

4.Start the UPS in Normal mode according to the instructions in the operation chapter of the applicable Powerware 9390 installation and operation manual, listed in paragraph 1.5.

4.5.2Transferring the UPS to Maintenance Bypass

C A U T I O N

Only trained personnel familiar with the operation of this equipment should transfer loads. Failure to follow this transfer sequence may cause loss of power to loads or overload protection devices to activate.

In Bypass mode, the critical load is not protected from commercial power interruptions and abnormalities.

1.Press the CONTROLS pushbutton on the main menu bar. The System Controls screen appears.

2.Press the BYPASS pushbutton on the System Controls menu bar.

The UPS transfers to Bypass mode and the critical load is immediately supplied by the bypass source. If the bypass source is not available, the power processor remains on and an alarm sounds.

3.Verify that the BYPASS status indicator is illuminated, indicating the UPS is operating in Bypass mode.

4.Press the pushbutton on the System Controls screen to display System Controls Screen 2.

5.Press the PM OFF pushbutton on the System Controls menu bar.

The PM status indicates SHUTDOWN. The input and output contactors open, the battery breaker or disconnect is tripped, and the power module is turned off. The bypass source supplies the critical load.
