Locking the Generator Set Out of Service

NOTICE

Automated Machinery

Accidental or remote starting of the generator set can cause severe personal

injury or death.

Isolate all auxiliary supplies and use an insulated wrench to disconnect the

starting battery cables, negative (–) cable first.

Before any work is carried out for maintenance, etc., the generator set must be

immobilized. Even if the generator set is put out of service by pressing the Off

switch on the Operator Panel (or the STOP button if applicable), the generator set

cannot be considered safe to work on until the engine is properly immobilized, as

detailed in the following procedure.

NOTICE

Refer also to the engine-specific Operator Manual, if applicable. This manual

contains specific equipment instructions that may differ from the standard

generator set.

To immobilize the generator set:

1. Press the Off switch from the display and then press the E-Stop button to shut

down the engine. This will prevent the starting of the generator set regardless of

the Start signal source and will therefore provide an additional safety step for

immobilizing the generator set. Alternatively, make sure the generator set is in

manual mode (which allows it to be started by manually pushing the buttons).

NOTICE

When the E-Stop button is pressed, the Operator Panel indicates the

Shutdown condition by illuminating the red Shutdown status LED

and displaying a message on the graphical LCD display.

2. Thoroughly ventilate the generator set before disconnecting any leads.

3. Turn off and disconnect the heater (where fitted) from the AC source before

disconnecting the battery cables.

4. Turn off and disconnect the battery charger (where fitted) from the AC source

before disconnecting the battery cables.

5. Turn off the fuel supply to the engine.

6. Disconnect the battery. Disconnect the negative (–) cable first, using an

insulated wrench.

7. Place warning notices at each of the above locations that state, "Maintenance

in Progress – Immobilized for Safe Working."
