About this guide

This guide contains the very basic information
about the mechanical and electrical installation
of the ACS850-04 drive module (0.37 to
45 kW). For complete documentation, see
ACS850-04 Drive Modules (0.37 to 45 kW)
Hardware Manual (code: 3AUA0000045496
[English]).

Safety instructions

WARNING! All electrical installation
and maintenance work on the drive
should be carried out by qualified
electricians only.
Never work on the drive, the braking chopper
circuit, the motor cable or the motor when input
power is applied to the drive. Always ensure by
measuring that no voltage is actually present.
A rotating permanent magnet motor can
generate a dangerous voltage. Lock the motor
shaft mechanically before connecting a
permanent magnet motor to the drive, and
before doing any work on a drive system
connected to a permanent magnet motor.

Mechanical installation

Fasten the drive module to the mounting base
using screws through the four mounting holes.
Frame A and B can be mounted onto a DIN rail;
it is however highly recommended to fasten
these modules to the mounting base also by
two screws through the lower mounting holes.
Removing the cover assembly
The cover assembly needs to be removed
before the installation of optional modules and
the connection of control cabling. Follow this
procedure to remove the cover assembly. The
numbers refer to the illustrations below.
• Press the tab (1) slightly with a screwdriver.
• Slide the lower cover plate slightly
downwards and pull it out (2).
• Disconnect the panel cable (3) if present.
• Remove the screw (4) at the top of the cover
assembly.
• Carefully pull the lower part of the base
outwards by the two tabs (5).
Refit the cover in reverse order to the above
procedure.
