To Make an Interlock Circuit

The interlock circuit is designed to prevent electrical shock when a user touches the
measurement terminals.
You must install an interlock circuit on a shielding box to prevent hazardous
voltages when the door of the shielding box is open.
Figure 2-2 shows the pin assignments of the interlock connector mounted on a
connector plate or test fixture.

Potentially hazardous voltages may be present at the Force, Guard, and Sense
