J3 Interlock

This is intended to connect to a test area enclosure switch that opens when
the door is opened. If not used, a jumper plug (p/n 049-635-901) must be
installed. If you are building a cable, maximum length is 30.48 m (100 ft)
with 24 gauge wire. Switch should be wired normally closed, such that when
the switch opens, an interlock is generated.
