3.6. Guidelines for Enclosure Mounting (IP20 Units)
IP20 drives are suitable for use in pollution degree 1 environments, according to IEC-664-1. For pollution degree 2 or higher
environments, drives should be mounted in a suitable control cabinet with sufficient ingress protection to maintain a pollution
degree 1 environment around the drive.
Enclosures should be made from a thermally conductive material.
Ensure the minimum air gap clearances around the drive as shown below are observed when mounting the drive.
Where ventilated enclosures are used, there should be venting above the drive and below the drive to ensure good air circulation.
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 BFI 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 adequate ventilation paths and clearances are provided to allow air to circulate
through the drive heatsink. Beijer Electronics 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.
