4.4.1 SYSTEM TURN-OFF, MODELS 390 and 3120-AMX

This paragraph describes the procedure used to turn off the 390 and 3120-AMX Power
Sources.
The 390 and 3120-AMX Power Sources are turned off by:
1. Setting the OUTPUT POWER Switch of the Master chassis (which has the controller
installed) to the OFF position.
2. Opening the INPUT POWER circuit breaker of the Slave chassis.
3. Opening the INPUT POWER circuit breaker of the Master chassis.
It is recommended that only the OUTPUT POWER switch of the Master chassis be used to remove
power to a load. The INPUT POWER switch of the Slave chassis should never be turned to the OFF
position with a load attached to the system as it will subject the Master chassis to all the load current
being delivered by the system. This will cause an overtemp shutdown if the load exceeds the Master
chassis' system ratings. Also, the Master chassis INPUT POWER switch should never be used to
remove power to a load since it drives all the control circuits for the paralleled system.
