Degrees of Protection

Available enclosures:

• IP 21 / 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.
• IP 54 / UL type 12 enclosure. This enclosure provides protection from airborne
dust and light sprays or splashing water from all directions.
Compared to the IP 21 / UL type 1 enclosure, the IP 54 / UL type 12 enclosure has:
• The same internal plastic shell as the IP 21 enclosure
• A different outer plastic cover
• An additional internal fan to improve cooling.
• Larger dimensions
• The same rating (does not require a derating).
