Safety instructions

Chapter overview

This chapter contains the safety instructions you must follow when installing, operating and servicing the drive.
If ignored, physical injury or death may follow, or damage may occur to the drive, the motor or driven
equipment. Read the safety instructions before you work on the unit.

To which products this chapter applies

The information is valid for the whole range of the product DCS550.

Usage of warnings and notes

There are two types of safety instructions throughout this manual: warnings and notes. Warnings caution you
about conditions, which can result in serious injury or death and/or damage to the equipment, and advice on
how to avoid the danger. Notes draw attention to a particular condition or fact, or give information on a
subject. The warning symbols are used as follows:

Dangerous voltage warning warns of high voltage, which can cause physical injury or death
and/or damage to the equipment.

General danger warning warns about conditions, other than those caused by electricity, which
can result in physical injury or death and/or damage to the equipment.

3

Electrostatic sensitive devices warning warn of electrostatic discharge, which can damage
the equipment.

Installation and maintenance work

These warnings are intended for all who work on the drive, motor cable or motor. Ignoring the instructions can
cause physical injury or death and/or damage to the equipment.

WARNING!

1. Only qualified electricians are allowed to install and maintain the drive!

 Never work on the drive, motor cable or motor when main power is applied. Always ensure

by measuring with a multimeter (impedance at least 1 Mohm) that:

1. Voltage between drive input phases U1, V1 and W1 and the frame is close to 0 V.

2. Voltage between terminals C+ and D- and the frame is close to 0 V.

 Do not work on the control cables when power is applied to the drive or to the external

control circuits. Externally supplied control circuits may cause dangerous voltages inside the
drive even when the main power on the drive is switched off.

 Do not make any insulation resistance or voltage withstand tests on the drive or drive

modules.

 Isolate the motor cables from the drive when testing the insulation resistance or voltage

withstand of the cables or the motor.

 When reconnecting the motor cable, always check that the C+ and D- cables are connected

with the proper terminal.

Note:
 The motor cable terminals on the drive are at a dangerously high voltage when the main

power is on, regardless of whether the motor is running or not.

 Depending on the external wiring, dangerous voltages (115 V, 220 V or 230 V) may be

present on the relay outputs of the drive system (e.g. RDIO).

 DCS550 with enclosure extension: Before working on the drive, isolate the whole drive

system from the supply.
