ACQ550-U1 User’s Manual 15
Installation
Confirm that the enclosure is appropriate, based on the site contamination level:
• IP21 / UL type 1 enclosure: The site must be free of airborne dust, corrosive
gases or liquids, and conductive contaminants such as dripping water,
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.
• 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 hood, see the note in chapter
Technical data , page 300 .
Suitable mounting location
Confirm that the mounting location meets the following constraints:
• The drive must be mounted vertically on a smooth, solid surface, and in a suitable
environment as defined above. For horizontal installation, contact your local ABB
representative for more information.
• The minimum space requirements for the drive are the outside dimensions (see
section
Outside dimensions on page 294 ), plus air flow space around the drive
(see section Cooling on page 291 ).
• The distance between the motor and the drive is limited by the maximum motor
cable length. See section
Motor connection specifications on page 279 .
• The mounting site must support the drive’s modest weight. See section Weight on
page 295 .
