UPS Operating Instructions

7.Press the NORMAL pushbutton on the System Controls menu bar of the UPM.

8.Observe the following messages appear sequentially on the power module (PM) status line of the UPM:

DC STARTING INVERTER STARTING INVERTER SYNCING READY

ONLINE

The rectifier and inverter turn on. When the inverter reaches full voltage, the UPM synchronizes with the output and closes output contactor K3. The UPM is online and in Normal mode with the NORMAL status indicator illuminated and in parallel with the other system UPMs.

9.Close battery breakers for the UPM any time after INVERTER SYNCING or CLOSE BATTERY appears on the display.

10.2.7Parallel System and Critical Load Shutdown

To perform maintenance or service on the critical load, shut down power to the load by performing the following procedure:

C A U T I O N

Using the following procedure removes all output from the critical load. You should use this procedure only when you need to de-energize both the parallel system and the critical load.

1.Turn off all equipment that is being powered by the parallel system.

2.Press the CONTROLS pushbutton on the main menu bar on any UPM. The System Controls screen appears.

3.Press the BYPASS pushbutton on the System Controls menu bar of any UPM. The UPMs transfer to Bypass mode.

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

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

The power module (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.

6.Repeat Steps 2, 4, and 5 for each UPM, except the last UPM. The last UPM must be shut down using the REPO pushbutton switch. See “Using the Parallel System Remote Emergency Power-Off Switch” in paragraph 10.2.9.

7.To shut down the last UPM, press the REPO pushbutton switch.
