3.8. 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 drive 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. The Manufacturer recommends 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.
3.9. Guidelines for mounting IP55, and IP66 Units
Before mounting the drive, ensure that the chosen location meets the environmental condition requirements for the drive shown in
section 13.1
The drive must be mounted vertically, on a suitable flat surface
The minimum mounting clearances as shown in the table below must be observed
The mounting site and chosen mountings should be sufficient to support the weight of the drives
