1.5.1 Installation considerations
Keep in mind the following points when selecting a location.
• Locate the unit away from heat sources because of heat that can build up inside the
cabinet.
• Select a location where the vibration is minimal.
• Locate the equipment away from places subject to water splash and rain.
• Make the service clearance of 100 mm in front of the vent hole (front and rear sides).

• Leave sufficient space at the sides and rear of the unit to facilitate maintenance.
• Connect the ground wire between the earth terminal on the chassis and the ship's
earth.
• A magnetic compass will be affected if the unit is placed too close to the magnetic
compass. Observe the compass safe distances on page ii to prevent compass mal-
function.
