9) Chassis Intrusion Lead (4-1 pin CHASSIS) Also in Panel Connectors
This requires an external detection mechanism such as a chassis intrusion moni-
tor/sensor or microswitch. The sensor is triggered when pins 3 and 4 are opened.
If the chassis intrusion lead is not used, a jumper cap must be placed over pins
3 and 4 to close the circuit.

tion when using ribbon cables with pin 5 plugged).
