Safety Instructions
DCS 600 Operating Instructions i
Overview
This chapter contains safety instructions which must be complied
with during installation, operation and maintenance of the power
converters series DCS 600 MultiDrive. If these instructions are
not complied with, this may result in injuries (perhaps even with
fatal) or in damage to the power converter, the motor and the
driven machine. Before starting with any work whatsoever at or
with this unit, you must
read the information given in this chapter.
Warnings
Warnings provide information on states which if the specified
procedure for the state concerned is not meticulously complied
with may result in a serious error, in major damage to the unit, in
injury to persons and even in death.
They are identified by the following symbols:
Danger: High Voltage! This symbol warns you of
high voltages which may result in injuries to persons
and/or damage to equipment. Where appropriate, the
text printed adjacent to this symbol describes how
risks of this kind may be avoided.
● All electrical installation and maintenance work on the thyristor
power converter must be carried out by properly qualified staff
who have been thoroughly trained in electrical engineering.
● The thyristor power converter and its adjacent units must be
properly earthed by qualified professionals.
● You must NEVER perform any work on the thyristor power
converter while it is still switched on. First switch the unit off,
use a measuring instrument to make absolutely sure that the
power converter has really been de-energized, and only then
you may start with the work concerned.
● Due to external control circuits, there may be dangerously
high voltages present at the thyristor power converter even
after the line voltage has been switched off. So always work
at the unit with appropriate caution! Non-compliance with these
instructions may result in injury (or even death!).
