Mounting considerations

•

Leave sufficient space at the sides and rear of your unit for ease of maintenance.

•

Locate the unit as near to the power source as possible.

•

The location should be out of direct sunlight because of heat that can build up inside the

cabinet.

Choose a location not subject to rain and salt spray.

•

Locate the unit well away from sources of noise such as motors, alternators and

generators.
