1.5.3 Installing the Feed/Spindle Servopacks (Amplifiers)
• The Servopack is to be wall-mounted vertically using screws or bolts.
• Locate the Servopack so that inspection, maintenance and part replacement can be easily
made.
• The Servopack will generate some heat, so mount with sufficient space around the unit.
• To reduce heat generation, mount the cooling fin external to the Servopack’s enclosure with
the fan blowing air on the cooling fin @ 2.5m/s.
• Internal air should not be blown directly onto the Servopack since this could cause dust con-
tamination.
