supply.
This feature is useful while performing maintenance or service and shall only be executed by
authorized technical service personnel.
In order to transfer to Manual Bypass without interruption, do the following instruction
respectively;
Open the front cover.
Switch the Manual Bypass circuit breaker (F3) to “ON” position.
See “Bypass” written on LCD.
Switch the output circuit breaker (F2), the battery circuit breakers (F5) –the breakers on external
battery cabinets if any-, the input circuit breaker (F1) and inrush circuit breakers (F6) to “0”
position.
