UPS Startup on Battery

NOTE Before using this feature, the UPS must have been powered by utility power at
least once so that the UPS can auto-detect the frequency (50 or 60 Hz).

1. Remove the front panel. Lift from the bottom of the panel and

then pull out (see Figure 5 on page 22).

2. Verify that the Maintenance Bypass switch is in the UPS

position.

3. Turn the UPS battery breaker CB1 and optional CB2 to the ON

position. If you have additional battery cabinets, turn the circuit
breakers on all battery cabinets to the ON position.

4. Start the UPS by turning on the UPS ON/OFF switch (the

position).

5. Press the Battery Start pushbutton below the UPS control panel

(see Figure 14 on page 39) and hold for approximately five
seconds.

The UPS checks its internal functions and supplies power to the
output. The UPS starts in approximately one minute. The UPS
ON, ON BATTERY, and LOAD indicators illuminate. The
audible alarm sounds; press the RESET pushbutton on the LED
panel to clear the alarm.

6. Reinstall the front panel.
