Emerson 240V Manuel D’Utilisation

The Power Module rectifiers derive power from a utility AC source and supply regulated DC power to 

the inverter. The module’s inverter regenerates precise AC power to supply the connected equipment. 

The battery charger is in the Power Module and maintains a float-charge on the batteries.

When AC utility fails, the connected equipment is supplied power by the inverter, which obtains 

energy from the Battery Modules. The output power equipment will not be interrupted during the 

failure or restoration of the AC utility source.

After a power outage and complete battery discharge, and once AC utility is restored, the UPS will 

automatically restart and resume supplying power to connected equipment. This feature is enabled at 

the factory, but can be disabled by the user. The user can also program two auto restart delay settings:
1. Battery capacity level (%)
2. Countdown timer

The bypass provides an alternate path for power to the connected equipment and operates in the fol-

lowing manner:

In the event of an internal fault or should the inverter overload capacity be exceeded, the UPS 

performs an automatic transfer of the connected equipment from the inverter to the bypass 

source.

Should the UPS need to be taken out of service for limited maintenance or repair, manual activa-

tion of the bypass will cause an immediate transfer of the equipment from the inverter to the 

bypass source.
