1.4 Processor Unit
Mounting considerations
When selecting a mounting location, keep in mind the following points:
• Locate the processor unit away from heat sources because of heat that can build up inside the
cabinet.
• Locate the unit away from places subject to water splash and rain.
• Leave sufficient space at the sides and rear of the unit to facilitate maintenance, referring to the
outline drawing.
• A magnetic compass will be affected if the processor unit is placed too close to it. Observe the
compass safe distances on page ii to prevent interference to a magnetic compass.
Mounting procedure
Fix the unit with four M6 bolts or self-tapping screws.
