V-BELT SET 6N6655 - Caterpillar

When you service an electric power generation set or when you repair an electric power generation set, follow the procedure below:
Stop the engine.
Illustration 1 g00104545
Attach a "DO NOT OPERATE" or similar warning tag to the engine prime mover starting circuit. Disconnect the engine starting circuit.
Disconnect the generator from the distribution system. When possible, remove the HV circuit breaker to the test position. This will ensure complete isolation of generator winding to the bus.
Lock out the circuit breaker. Attach a "DO NOT OPERATE" or similar warning tag to the circuit breaker. Refer to the electrical diagram. Verify that all points of possible reverse power flow have been locked out.
Remove the fuses for the HV transformers for the following circuitry:
power
sensing
control
Attach a "DO NOT OPERATE" or similar warning tag to the generator excitation controls.
Remove the cover of the generator's terminal box (high voltage outlet).
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.
Determine that the generator is in a de-energized condition. Add ground straps to the HV conductors or terminals. During the entire work period, these ground straps must remain connected to the conductors and to the terminals.
