Attach a "DO NOT OPERATE" or similar warning tag to the generator excitation controls.
Remove the cover of the generator's terminal box.
Use an audio/visual proximity tester to verify that the generator is de-energized. This tester must be insulated for the proper voltage rating. Follow all guidelines to verify that the tester is operational.
Determine that the generator is in a de-energized condition. Add ground straps to the conductors or terminals. During the entire work period, these ground straps must remain connected to the conductors and to the terminals.
