Guidelines For Enclosure Mounting - Ip20 Units - Invertek Optidrive E3 User Manual

3.4. Guidelines for Enclosure Mounting – IP20 Units
 I P20 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.
 E nclosures should be made from a thermally conductive material.
 E nsure the minimum air gap clearances around the drive as shown below are observed when mounting the drive.
 W here 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.
 I n any environments where the conditions require it, the enclosure must be designed to protect the Optidrive 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.
 H igh moisture, salt or chemical content environments should use a suitably sealed (non-vented) enclosure.
 T he enclosure design and layout should ensure that the adequate ventilation paths and clearances are left to allow air to circulate
through the drive heatsink. Invertek Drives recommend the following minimum sizes for drives mounted in non-ventilated metallic
enclosures:

Dimension Z assumes that the drives are mounted side-by-side with no clearance.
Typical drive heat losses are 3% of operating load conditions.
NOTE
Above are guidelines only and the operating ambient temperature of the drive MUST be
maintained at all times.
