MANUAL OPERATION WITH UTILITY AVAILABLE
Under normal circumstances, the UPS will be operated with utility available. The
UPS can operate in three possible modes with utility available:
NORMAL MODE OPERATION - UPS ON LED will be on and the inverter
will provide power to the load.
BYPASS MODE OPERATION - BYPASS LED will be on and the bypass
will provide power to the load directly from the utility.
OUTPUT OFF MODE OPERATION - UPS ON and BYPASS LEDs will be
off and the load will not have power. AC LINE LED will be on and batteries
will recharge.
STARTING THE UPS WITH UTILITY AVAILABLE
1. Ensure the load equipment is turned off, and all loads are properly
connected to the UPS output.
2. Verify that the utility supplying the UPS is turned on by closing any circuit
breaker or switch on the supply side of the UPS.
3. Turn On (Close) the BATTERY circuit breaker.
4. Turn ON (Close) the INPUT and OUTPUT circuit breakers. After a start-up
sequence, the AC INPUT LED should be on. If this LED is not on, verify that
the utility is turned on to the UPS from any external distribution panel or
isolating switch.
5. After about 10 seconds, the UPS will automatically default to BYPASS
MODE OPERATION. The BYPASS LED should be on. The load will now
receive power, but is not protected from disturbances in the utility.
6. Press the UPS ON/ALARM/BATTERY TEST button for at least one second
until you hear the audible alarm "beep" to signal acceptance of the
command. After a delay of about 10 seconds, the BYPASS LED will
extinguish, and the UPS ON LED should light. The UPS will then initiate a
self-test and battery test. When these tests are complete, the UPS is ready
for NORMAL UPS OPERATION.
7. Confirm that the UPS ON and AC INPUT LEDs are on and the BATTERY
and BYPASS LEDs are off.
8. Connected load equipment may now be turned on.
