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 3-11 shows the pin assignments of the interlock connector that should be
mounted on a connector plate or test fixture.
