6.1 Danger information
WARNING
This unit carries a dangerous voltage and contains dangerous rotating parts (fans). Ignoring the safety
and warning information may result in death, severe personal injury or damage to property.
You are responsible for mounting the power unit, the motor, the line reactor and any other equipment
in accordance with appropriate safety regulations (e.g. DIN, VDE); equally, you must ensure that all
other relevant national and local regulations are met with regard to cable ratings and protection,
grounding, disconnectors, overcurrent protection, etc.
The most important factors for protecting people are the DIN/VDE protective measures and safety reg-
ulations. If there are no protective earth connections on the equipment, commutating reactor or the
motor, personal injuries are inevitable, since the surfaces may carry dangerously high voltages.
During operation, the principles on which the power converter and the motor work lead to leakage cur-
rents to earth that are dissipated via the specified protective earths and may result in a current-oper
-
ated e.l.c.b on the input side blowing prematurely.
In the case of a short-circuit to frame or to ground, a direct proportion may arise in the leakage current
that makes triggering a higher level current-operated e.l.c.b either more difficult or totally impossible.
Make the PE connection in accordance with DIN EN 60204/VDE 0113 Part 1/06.93; Section 8.2.2 tak-
ing into account provisional standard EN 50178/ VDE 0160/11.94, Sections 5.3.2.1 and 8.3.4.4.
Before carrying out commissioning, check whether the plastic covers over the power stage connec-
tions are in place.
When an error occurs, the drive is de-energised and the motor coasts to stop. This fact must be taken
into account particularly for hoist and lifting drives.
