4.1.2 System On/Off Circuit Breaker
The circuit breaker located on the top left side of the front panel of the unit and disconnects the
three phase Line input. As such, the circuit breaker acts as a power on/off switch for the Lx
Series unit.
When the input current rating of the Lx/Ls Series AC power source is exceeded or an input over
voltage condition occurs, the circuit breaker will trip.
Note that for multi-chassis systems, it is recommended to turn the Master unit ON first and then
the Auxiliary unit(s). To turn the system off, turn OFF the Auxiliary unit(s) first and then the
Master unit.
