While operating in the inverter mode, placing the input breaker in the "OFF"
position will switch the UPS to the DC supply backup mode.
The output of the UPS will continue uninterrupted to the load. The unit must be in the
bypass mode at the time that the breaker is placed in the "OFF" position for the UPS
to shutdown power to the load.
After an Emergency Power Off (EPO), DO NOT reset the breaker until the UPS
internal circuits have been fully discharged.
The UPS could be damaged if the unit is not fully discharged before the breaker is
reset.
