1) Operate the AC line circuit breaker in the service entrance box to the OFF position.
If the power supply is located at a head end or other customer premise site, ensure
that the branch circuit breaker chosen to protect the AC receptacle for the power
supply is operated to the OFF position.
2) Operate the BATTERY CIRCUIT BREAKER on the front panel of the inverter
module to the OFF (0) position.
3) Apply the system load to the OUTPUT connector on the front panel of the power
supply. Do not attempt to load the power supply to a level greater than its total rated
output of 600, 900 or 1350 VA, depending on the model being used. Long-term
overloads can permanently damage your power supply.
