SAFETY NOTES

The means of disconnecting power from a station cabinet is the cabinet power supply plug.

•

When conducting repair/maintenance, disconnect the cabinet power supply plug from the AC source.

•

In European applications, equipment must be installed in a closed cabinet.

•

Only replace components with components specified by M/A-COM Private Radio Sys tems.

Description

The isolator has an internal load connected to an RF
detector (sensor), the output from the sensor is continually
monitored by the sttion for a fault conditon (high VSWR).
Once the station detects a sensor voltage above the threshold
the transmitter is automatically de-keyed and a FAULT con­dition is reported.

IMPORTANT:

SENSOR VOLTAGE

The sensor output must be connected to
P108 on the Interface Board when the Iso­lator is used, failure to m ake this connection
with the Isolator installed will cause the
isolator to be damaged under high VSWR
conditions.
