Installation & Operating Instructions

3.5 Guidelines for Enclosure Mounting (IP20 Units)
• Installation should be in a suitable enclosure, according to EN60529 or other relevant local codes or standards.
• Enclosures should be made from a thermally conductive material.
• Where vented enclosures are used, there should be venting above the drive and below the drive to
ensure good air circulation – see the diagram below. Air should be drawn in below the drive and expelled
above the drive.
• In any environments where the conditions require it, the enclosure must be designed to protect the Fenner
QD:Neo against ingress of airborne dust, corrosive gases or liquids, conductive contaminants (such as
condensation, carbon dust, and metallic particles) and sprays or splashing water from all directions.
• High moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure.
The enclosure design and layout should ensure that the adequate ventilation paths and clearances are left
to allow air to circulate through the drive heatsink. Fenner recommend the following minimum sizes for
drives mounted in non-ventilated metallic enclosures:-

Note:
Dimension Z assumes that the drives are mounted side-by-side with
no clearance
Typical drive heat-losses are 3% of operating load conditions
Above are guidelines only and the operating ambient temperature of
the drive MUST be maintained at all times.
3.6 Mounting the Drive (IP20 Units)
• IP20 units are intended for installation within a control cabinet.
• When mounting with screws
- Using the drive as a template, or the dimensions shown above, mark the locations for drilling
- Ensure that when mounting locations are drilled, the dust from the drilling does not enter the drive
- Mount the drive to the cabinet backplate using suitable M5 mounting screws
- Position the drive, and tighten the mounting screws securely
• When DIN rail mounting (Frame Size 2 Only)
- Locate the DIN rail mounting slot on the rear of the drive onto the top of the DIN rail first
- Press the bottom of the drive onto the DIN rail until the lower clip attaches to the DIN rail
- If necessary, use a suitable flat blade screwdriver to pull the DIN rail clip down to allow the drive to mount
securely on the rail
- To remove the drive from the DIN rail, use a suitable flat blade screwdriver to pull the release tab
downwards, and lift the bottom of the drive away from the rail first.
