3.4.5 MASTER - SLAVE PARALLELING INTERCONNECTIONS (M5283) (cont.)
SYSTEM TURN-OFF, PARALLELED SYSTEM
This paragraph describes the procedure used to turn off the paralleled systems.
The paralleled systems 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.
CAUTION
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.
CONNECTION OF THE THREE TO FIVE CHASSIS
Interconnection for larger systems (3-5 power sources) is similar to these instructions with the
exception of output wiring to the load. For instructions on how to install and operate a higher power
system, refer to section 9.0 of this manual.
