Starting the UPS
Turn the main circuit breaker (MCCB) on the back of the UPS (see pages 47-48) to the ON position. The
breaker should normally remain in the ON position.
Verify that the ON-LINE LED on the front panel (see page 32 and 33) lights green. All LED’s on the front
panel may light for a moment when the input breaker is turned on. This is normal. The UPS will now be
supplying power in the bypass mode.
CAUTION
operation, charge the batteries for at least 24 hours (input breaker on) before
operating the connecting load.
Using the UPS without charging the battery shortens the battery backup operation
time, which may result in the destruction of data in case of a power failure.
Press RUN key to begin UPS operation (see page 29 for startup screens).
CAUTION
If the input breaker is turned off while UPS is in the bypass state, the output
power stops. Any load devices will lose power.
Ensure that all sensitive loads have been previously shut down.
Stopping the UPS
To stop the UPS press and hold the STOP key approximately 1 second until the ON-LINE LED changes
from green to off. The UPS is now in the bypass mode.
To completely stop the UPS, turn the input breaker at the back of the UPS to the OFF position.
