INTERLOCK

1 and 2

Two plug receptacles for connecting external

interlock switches. Two hand interlock switches and a

foot switch are supplied; however, in the event that a

hand interlock is replaced with a test area interlock,

the system must be constructed so that the interlock

switches are closed when the test area gate or gates

are closed. The interlock wiring must be run as a

twisted pair to minimize electromagnetic coupling

into the system. This interlock system should be

wired such that connection is made to the A and B

sockets of the SAFETY INTERLOCK receptacle.

When the interlock loop is opened the test is

automatically terminated.

test lead.
