3.4. Enclosure mounting
For applications that require a higher IP rating than the IP20 offered by the standard drive, the drive must be mounted in a suitable metallic
enclosure. The following guidelines should be observed for these applications:
For IP20 Optidrives, install in a suitable enclosure, according to EN60529 if specific Ingress Protection ratings are required.
Enclosures should be made from a thermally conductive material
Where vented enclosures are used, there should be venting above 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 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.
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. Invertek Drives recommend the following minimum sizes for drives mounted in non-ventilated metallic enclosures:-
