Technical data

Degrees of protection

Available enclosures:

• IP21 / UL type 1 enclosure. The site must be free of airborne dust, corrosive

gases or liquids, and conductive contaminants such as condensation, carbon

dust and metallic particles.

• IP54 / UL type 12 enclosure. This enclosure provides protection from airborne

dust and light sprays or splashing water from all directions.

Note: UL type 12 enclosure is not available for type ACS550-01-290A-4.

Compared to the IP21 / UL type 1 enclosure, the IP54 / UL type 12 enclosure has:

• the same internal plastic shell as the IP21 enclosure

• a different outer plastic cover

• an additional internal fan to improve cooling

• larger dimensions

• the same rating (does not require a derating).
