Installation
3.2 Clearance for Cooling Air Circulation
>25mm
>3mm
>25mm
>3mm
Additional Clearance is required:
• for side mount and rear mount AC line filters
• if there are other accessories installed
• for cables and wires connected to the top, front and bottom of
the drive
• when the drive is mounted adjacent to noise sensitive equipment
or clean wire ways
3.3 Shielding and Grounding
• Use single-point grounding (SPG) for panel-mounted controls.
• Tie the SPG for all enclosures to earth ground at the same point.
• Individually connect the system ground and equipment grounds for all panel-mounted enclosures to the SPG
for that panel using 14 AWG (2.5 mm
2 ) or larger wire.
• Ground the chassis to the mounting. Use 14 AWG (2.5 mm 2 ) or larger wire to join the enclosure to earth ground.
• Install a lock washer between the enclosure and ground terminal. For maximum contact between the terminal
and enclosure, remove paint in a minimum radius of 0.25 in (6 mm) around the screw hole of the enclosure.
• Ground the shielded cable at both the drive end and at the motor end.
• If the PositionServo drive continues to pick up noise after grounding the shield, add an AC line filtering device
and/or an output filter (between the drive and servo motor).
