Airflow and Ventilation Requirements

During drive operation, air is circulated by fans at the bottom of the power

structure. If the structure is placed in the upper portion of the enclosure, the fan

will be in the middle portion of the enclosure. Therefore, to achieve sufficient

cooling of the drive, each enclosure must provide:

• Openings for cooling air intake in the door/front panel at and/or below

the level of the fans.

• Openings for hot air exhaust at the top of the enclosure.

ATTENTION: To guard against equipment damage caused by excessive heat,

proper airflow must be available at all times. Refer to the guidelines below.

IMPORTANT

To allow free air circulation, the protective screen/cover at the bottom of the

enclosure must be a mesh sheet metal screen. Additionally, the busbar screen/

cover and choke upper support must be equipped with holes.

IMPORTANT

If a flat roof is used, mount a V-shaped air guide on the underside of the roof to

direct the air flow horizontally.
