Description

The Alarm Power IOM comes with four Bussman

 

GMT 7.5A, 60V fuses. Two of the fuses are used to

 

protect the redundant DC power inputs (A and B) and

 

the other two fuses are provided as spares. The chassis

 

will operate with only one power source but two

 

independent sources are recommended to provide

 

power supply redundancy.

 

Power, alarm, and grounding connections are made to

 

the connector panel at the bottom rear of the chassis.
