a. Verify that the DC circuit is de-energized.
b. Verify that the ground wire is connected to the grounding lug on the rear of the switch.
The grounding lug is identified by the international symbol for earth ground:
c. Verify that the DC power input cables are properly connected to the DC power supplies at the
rear of the switch.
