POWERING DOWN THE UPS WITH UTILITY AVAILABLE
1. Shutdown all connected load equipment.
2. Press the OUTPUT OFF/BYPASS button once until a "beep" is heard. The
UPS ON LED will extinguish and the BYPASS LED will light if the BYPASS
voltage is within an acceptable range. The load is now powered through the
BYPASS and there is no UPS protection. The UPS will remain in BYPASS
MODE OPERATION until the user continues with the next step to turn the
UPS off.
3. Press the OUTPUT OFF/BYPASS button for at least 1 second, twice, within
a 4 second time interval. The BYPASS LED will extinguish and all power to
the load will stop. The UPS is in OUTPUT OFF MODE OPERATION and the
AC LINE LED will be on.
4. To isolate the UPS, turn off the INPUT, OUTPUT, and BATTERY breakers
on the rear of the UPS. For complete isolation, turn off the utility to the UPS.
ALTERNATE QUICK POWERING DOWN THE UPS
The UPS will skip past BYPASS MODE OPERATION directly to OUTPUT OFF
MODE OPERATION even with utility available.
1. Shutdown all connected load equipment.
2. Press the OUTPUT OFF/BYPASS button for at least 1 second, twice, within
a 4 second time internal. The UPS ON LED will extinguish and the BYPASS
LED will light for a short period then extinguish and all power to the load will
stop. The UPS is in OUTPUT OFF MODE OPERATION and the AC LINE
LED will be on.
3. To isolate the UPS, turn off the INPUT, OUTPUT, and BATTERY breakers
on the rear of the UPS. For complete isolation, turn off the utility to the UPS.
NOTE: Pressing the OUTPUT OFF/BYPASS button will always remove the load
from UPS power protection. Pressing the OUTPUT OFF/ BYPASS button for at
least 1 second, twice, within a 4 second time interval will always remove power
from the load.
MANUAL OPERATION WITHOUT UTILITY
The UPS operating time is limited by available battery power without utility. The
UPS may be manually turned off after the loads have been turned off to prevent
the batteries from being completely drained. It may also be desirable to power
up the loads for a short time without utility power to support a critical operation.
With utility unavailable, the UPS has two possible modes:
BATTERY MODE OPERATION - UPS ON and BATTERY LEDs will be on and
the inverter will provide power to the load using battery power.
OUTPUT OFF MODE OPERATION – All LED’s will be off and the load will not
have power.
