GENERAL

The electrical system for the insulated container provides power to the interior light and receives power

from the refrigeration Unit (RU). The electrical system includes the plug to which the supply power is

connected, the interior light fixture, conduit protecting the wires between the light fixture and the switch,

the light switch and the pilot light on the container exterior.

INSPECT

1. Inspect the power entry connector on the rear of the IC and to the right of the RU light circuit. The

connector should be undamaged with the prongs straight and free of corrosion.

2. Connect a 120 VAC power source to the power entry connector.

3. Inspect the pilot light fixture on the front of the IC, above the door. The fixture should be free of

visible damage and clean with the lamp intact.

4. Inspect the interior light switch. The switch enclosure should be free of visible damage. The switch

movement should be easy while permitting the user to feel the switch action.

5. Examine the conduit between the switch and the light fixture. The conduit should be securely

fastened to the container surfaces and undamaged. The conduit should be firmly attached to the light

switch enclosure at one end and the light fixture at the other, with no wires exposed.

6. Examine the light fixture. Look at the cage, globe and light bulb to confirm that they are undamaged.

Check that the fixture is securely attached to the container wall.

7. Switch on the interior light and confirm that the light and the exterior pilot light both turn on when the

switch is on and turn off when the switch is off.
