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.
