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 DCS800, the converter modules DCS800-S0x size
D1 to D7, field exciter units DCF80x, etc. like the Rebuild Kit DCS800-R00-9xxx.
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.
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!
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. SDCS-IOB-2 and RDIO).
DCS800 with enclosure extension: Before working on the drive, isolate the whole drive
system from the supply.

Handling the Semiconductors, this chapter describes the handling of thyristors and thyristor modules.
Exchange of Thyristors for sizes D1 to D4, this chapter describes the exchange of thyristors in converters
sizes D1 to D4.
Exchange of Thyristors for size D5, this chapter describes the exchange of thyristors in converters sizes D5.
Exchange of Thyristors for size D6, this chapter describes the exchange of thyristors in converters sizes D6.
Exchange of Thyristors for size D7, this chapter describes the exchange of thyristors in converters sizes D7.
Exchange of SDCS-CON-4, this chapter describes the exchange of a SDCS-CON-4.
Service, this chapter contains hardware change information, firmware download and technical hints.
Preventive Maintenance, this chapter describes preventive maintenance of thyristor converters.
Appendix A: Spare Parts list, Appendix A contains the spare parts list.
Target group
This manual is designed to help those responsible for planning, installing, starting up and servicing thyristor
power converters.
These people should possess:
− basic knowledge of physics, electrical engineering, electrical wiring principles, components as well as
symbols used in electrical engineering and
− basic experience with DC drives and DC products.
Associated publications
A list of associated publications is published on the inner page of this manual’s cover, see DCS800 Manuals.
The above listed documentation can be found on the CD-ROM being attached to the DCS800 Quick Guide
(3ADW000191).
Storage and transport
If the unit has been in storage prior to installation or is transported to another location, care must be taken to
ensure that the environmental conditions are complied with (see DCS800 Hardware Manual).
