Suitable Environment And Enclosure - ABB ACH550-01 User Manual

Suitable environment and enclosure

Confirm that the site meets the environmental requirements. To
prevent damage prior to installation, store and transport the
drive according to the environmental requirements specified for
storage and transportation. See section
page 440.
Confirm that the enclosure (degree of protection) is appropriate,
based on the site containment level:
• IP21 type enclosure. The site must be free from airborne
dust, corrosive gases or liquids, and conductive
contaminants such as dripping water, condensation, carbon
dust, and metallic particles.
• IP54 type enclosure. This enclosure provides protection from
airborne dust and light sprays or splashing water from all
directions.
Compared to the IP21 enclosure, the IP54 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).
If, for some reason, an IP21 drive needs to be installed without
the conduit box or cover, or an IP54 drive without the conduit
plate or top cover, see the note on page 444.
