ACH550-UH User’s Manual 1-13
Installation
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 Ambient conditions on
page 1-326.
Confirm that the enclosure is appropriate, based on the site contamination level:
• 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.
• UL type 12 enclosure. This enclosure provides a degree of protection against
falling dirt; against circulating dust; and against dripping and light splashing of
non-corrosive liquids.
Suitable mounting location
Confirm that the mounting location meets the following constraints:
• R1…R6: The drive must be mounted vertically on a smooth, solid surface, and in
a suitable environment as defined above.
• The drive must be located in a suitable environment as defined above.
• The minimum space requirements for the drive are the outside dimensions (see
Outside dimensions – R1…R6 on page
1-323 or Outside dimensions – R7…R8
on page 1-324), plus air flow space around the unit (see Cooling
on page 1-318).
• The distance between the motor and the drive is limited by the maximum motor
cable length. See either Motor connection specifications on page 1-309, or
EN 61800-3 compliant motor cables on page 1-312.
• The mounting site must support the drive’s weight. See Weight on page 1-322.
Installing the drive
WARNING! Before installing the ACH550, ensure the input power supply to the drive
is off.
WARNING! Metal shavings or debris in the enclosure can damage electrical
equipment and create a hazardous condition. Where parts, such as conduit plates
require cutting or drilling, first remove the part. If that is not practical, cover nearby
electrical components to protect them from all shavings or debris.
