Enclosure Air Filter Replacement – UL Type 12/NEMA 12 Hinged Door

Wall Mount Enclosures

This procedure applies to drive with disconnect configurations in UL Type 12/NEMA

12 hinged door wall mount enclosures. This filter is located at the bottom of the

enclosure. Use the following procedure to check and replace filters.

1. On the enclosure, remove the screw holding the filter bracket in place.

2. Slide the filter bracket forward until the hooks on the bracket clear the slots on the

enclosure base. This step allows the filter and bracket to drop free from the

enclosure.
