UPS Operating Instructions

The following procedures provide instructions for operating the UPS or parallel system. For a description of the UPS control panel functions, see Chapter 9, “Using the Control Panel.”

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

NOTE Read this section of the manual and have thorough knowledge of parallel and UPS operation before attempting to operate any of the controls.

NOTE The UPS displays two minutes of battery run time at the initial startup. After a 24-hour charging period, the UPS automatically runs a battery test and the correct battery run time displays.

10.1 Single Module Operation

10.1.1 Starting the UPS in Normal Mode

To start the UPS system, perform the following procedure:

1.Close the UPS input feeder circuit breaker.

2.If the UPS is dual feed, close the UPS Bypass input feeder circuit breaker.

3.Observe the UPS control panel display becoming active, indicating logic power.

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

5.On the System Controls screen, the power module (PM) status should indicate

SHUTDOWN.

6.Press the NORMAL pushbutton on the System Controls menu bar.

If Auto Bypass is enabled, the critical load is immediately supplied by the bypass source, in Bypass mode, until the inverter turns on and the UPS transfers to Normal mode. The status indicator on the UPS control panel indicates the UPS is in Bypass mode. If Auto Bypass is not enabled, the UPS output remains off until the UPS transfers to Normal mode.
