3.3 OPERATING STATUS
The UPS has four different operating modes, as described below:
 Normal operation
 Bypass operation
 Battery operation
 Manual bypass
3.3.1 Normal operation
During normal operation all the circuit breakers/isolators are closed, except for MBCB
(maintenance bypass).
The rectifier is supplied by the AC three-phase input voltage, feeds the inverter and
compensates mains voltage as well as load variations, keeping the DC voltage constant. The
battery charger keeps the battery charged (floating or boost charge depending on the battery
type). The inverter converts the DC voltage into an AC sine-wave with stabilized voltage and
frequency, and also supplies the load via its static switch SSI.

3.3.2 Bypass operation
The load can be switched to bypass either automatically or manually. The manual changeover
can be performed by display forcing the load to bypass. In case of failure of the bypass line, the
load is switched back to inverter without interruption.
