SYSTEME
Function
If closed, this switch connects the UPS batteries to the DC/
DC converter stage to power the inverter in the event of a
mains failure.
This switch provides the primary power supply to the UPS.
In a confi guration with separate mains this switch only inter-
rupts the rectifi er power supply.
This completely isolates the UPS output by removing the volt-
age from the applications in any operating conditions. It is used
for the emergency shutdown of the system (internal ESD).
Continuous power supply to the load
Used for:
- routine or special maintenance operations (manual bypass)
- in the event of a UPS failure to power applications from the auxil-
iary mains while awaiting the intervention of technical personnel.
