The alarm monitor output connector (J3) provides a summary fault status output to a
summary alarm panel, or annuciator type device, or redundancy switching equipment.
2.4 Chassis Ground
A number 10-32 threaded ground stud (E1) is provided on the rear panel of the
equalizer. This ground stud is connected to the chassis and should be connected, via a

of the system installation.
This ground should be connected at all times for the safety of equipment service
personnel.
