Wiring the Interlock Safety Switches
The safety switch signals can be wired to single pole or double pole switches. Choose the
diagram below that matches your switch type and wire the switch as shown. If you are not
using Cirris safety switches, assure that your safety switch has normally open contacts. When
the operator wants to prevent hipot, the switch contacts must be open. To allow hipot, the
switch contacts must be closed. If the contacts open during a hipot test, the test will abort.
