ACS 400 User’s Manual 5
Units with IP 54/NEMA Type 12 & NEMA Type 4 Enclosures
The IP 54/NEMA Type 12 & 4 protection class has a different outer plastic cover. The IP 54/NEMA
Type 12 & 4 enclosures use the same internal plastic shell as the IP21 enclosure, but an internal
fan is added to improve cooling. This structure increases the dimensions compared to the IP 21
enclosure, but does not require a de-rating.

A complete set of dimensional drawings for the NEMA Type 12 & 4 ACS 400 drives is located in
“Appendix D” on page 167.
