About this guide

This guide contains the very basic information
about the mechanical and electrical installation
of the ACS850-04 drive module (1.1 to 45 kW).
For complete documentation see ACS850-04
Drive Modules (1.1 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.

Notes:
- If shielded supply (input) cable is used, and
the conductivity of the shield is less than 50%
of the conductivity of a phase conductor, use a
cable with a ground conductor (1) or a separate
PE cable (2).
- For motor cabling, use a separate ground
cable (3) if the conductivity of the cable shield
is less than 50% of the conductivity of a phase
conductor and the cable has no symmetrical
ground conductors.
