6.1 Danger information
WARNING
This unit carries dangerous voltage and contains dangerous rotating machine parts (fans). This
means that death, serious injury or considerable material damage can occur if the safety and warning
notices are not heeded.
The user is responsible for the assembly of the converter power unit, the motor, mains filter and the
other components according to applicable safety standards (e.g. DIN, VDE) and all other relevant na
-
tional or local regulations regarding conductor dimensions and fusing, grounding, circuit breakers,
overcurrent protection etc.
The protective measures and safety regulations according to DIN/VDE are binding for personal secu-
rity. If there are no PE connections on the unit, the mains filter or the motor, personal injury may be
caused since the surface may carry hazardous voltage.
During operation, the principles on which the converter and motor work, lead to leakage currents to
earth which are dissipated via specified protective earth connections and which may result in a current-
operated e.l.c.b. on the input side blowing prematurely.
A DC component in the fault current may occur in the event of a short-circuit to frame or earth fault
which makes a triggering of the higher-level current-operated e.l.c.b. more difficult or even impossible.
Make the PE connection according to DIN EN 60204-1 / VDE 0113 Part 1 / 01.97, Section 8.2.2. con-
sidering EN 50178 / VDE 0160/4.98, Sections 5.3.2.1 and 8.3.4.4.
Before commissioning check whether the plastic covers over the live parts (power part connections)
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.
