7.3.10 Using the UPS LOAD OFF Pushbutton or Command

A UPS Load Off is initiated by the LOAD OFF pushbutton from the main menu bar, the

Load Off command on the UPS Control Command screen, or Load Off command on

the Bypass Control Command screen. The UPS LOAD OFF controls the UPS output by

powering down the UPS and de-energizing the critical load.

The UPS (including Bypass) remains off until restarted.

To use the LOAD OFF pushbutton:

1. Press the LOAD OFF pushbutton.

The Load Off screen is displayed, providing a choice to proceed or abort the

shutdown.

C A U T I O N

All power to the critical load is lost when the LOAD OFF is selected in the following step. You should use this

feature only when you want to de-energize the critical load.

2. To shut down the UPS, press LOAD OFF from the Load Off menu bar, and hold for

three seconds. To abort the shutdown, press CANCEL.

When LOAD OFF is selected and held for three seconds, the input, output,

battery, and bypass backfeed contactors open, and the power module is turned

off.

C A U T I O N

Do not attempt to restart the system after Load Off until the cause of the shutdown has been identified and

cleared.

3. To restart the UPS after pressing the LOAD OFF pushbutton, follow the procedure

in paragraph 7.3.1 on page 7−11 or 7.3.2 on page 7−12.

W A R N I N G

Power is present inside the UPS cabinet sections until the upstream input feeder circuit breaker is opened.

To use the LOAD OFF command:

1. Press the CONTROLS pushbutton on the main menu bar. The System Status

screen is displayed.

2. On the System Status screen, select either the UPS or the BYPASS command.

3. Press the CONTROLS pushbutton on the System Status menu bar. The UPS or

Bypass Control Command screen is displayed.

4. On the Control Command screen, select LOAD OFF.

5. Press the SELECT pushbutton on the Command menu bar.

The Load Off screen is displayed, providing a choice to proceed or abort the

shutdown.
