UPS Shutdown
Performing a UPS shutdown turns off the power to your protected
equipment. Confirm the equipment is prepared for a power-off before
shutting down the UPS.
NOTE Do not perform a UPS shutdown if you want to use the Maintenance Bypass
feature on the optional PPDM (see “Using the PPDM” on page 54).
To perform a UPS shutdown:
1. Press and hold the Output Off button until the long beep
ceases (approximately three seconds).
The
µ
indicator remains lit indicating Normal mode, load
offline.
2. Switch the input breaker on the power processing unit to the
OFF (O) position.
The UPS enters Battery mode for several seconds. The
µ
indicator turns off and the UPS shuts down.
3. Unplug or remove utility power from the UPS.
4. When all LEDs are no longer illuminated on the UPS, switch
the circuit breaker to the OFF (O) position on each battery
cabinet.
Changing the Output Voltage
To change the operating voltage of the UPS:
1. Perform a UPS shutdown as described in the previous section.
2. Select the new voltage (see Step 7 on page 27). If you have a
PPDM, see Step 4 on page 41.
3. Restart the UPS by performing a UPS startup as described on
page 36. If you have a PPDM, see page 47.
