6. Attach a “DO NOT OPERATE” or similar warning
tag to the generator excitation controls.
7. Remove the cover of the generator's terminal box.
8. Use an audio/visual proximity tester in order to
verify that the generator is de-energized. This
tester must be insulated for the proper voltage
rating. Follow all guidelines in order to verify that
the tester is operational.
9. 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.
