The chapter describes the mechanical installation procedure of the drive.

Requirements for the installation site
The safe operation of this equipment depends upon its use in the appropriate
environment. The following points must be considered:
• The MicroFlex e150 must be installed indoors, permanently fixed and located so
that it can only be accessed by service personnel using tools. When installed in a
cabinet, the cabinet must have a volume of at least 0.19 m
3
(6.84 cu.ft). If not
installed in a cabinet, barriers around the equipment are required.
• The MicroFlex e150 must be secured by the slots in the flange. The protective
earth/ground (the threaded hole on the top of the MicroFlex e150) must be
bonded to a safety earth/ground using either a 25 A conductor or a conductor of
three times the peak current rating - whichever is the greater.
• Avoid locating the MicroFlex e150 immediately above or beside heat generating
equipment, or directly below water steam pipes.
• Avoid locating the MicroFlex e150 in the vicinity of corrosive substances or
vapors, metal particles and dust.
• Failure to meet cooling air flow requirements will result in reduced product lifetime
and/or drive overtemperature trips.
• The maximum suggested operating altitude is 1000 m (3300 ft).
• The MicroFlex e150 must be installed where the pollution degree according to
EN 60664 shall not exceed 2.
• The atmosphere must not contain flammable gases or vapors.
• There must not be abnormal levels of nuclear radiation or X-rays.
