4.4 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 AD700E 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. NIDEC INDUSTRIAL SOLUTIONS 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.
