Before installation
Check the installation site according to the requirements below. Refer to Dimension
drawings for frame details.
Requirements for the installation site
See Technical data for the allowed operation conditions of the drive.
The ACSM1-04 is to be mounted in an upright position. The wall the drive is to be
mounted on must be as even as possible, of non-flammable material and strong
enough to carry the weight of the drive. The floor/material below the drive must be
non-flammable.
Connection to an IT (ungrounded) or a corner-grounded power system
The internal EMC filter must be disconnected if the drive is to be supplied from a
corner-grounded power system or an IT power system [an ungrounded power
system or a high resistance-grounded (over 30 ohms) power system]. As the
procedure involves the removal of drive module covers, it is convenient to perform it
before the drive is installed.
See page 49 for directions.
