WARNING
The following
may occur
,
if you do not observe this warning information:
m
serious personal injury
m
death
The hazard is:
Electricity.
Voltage conducting parts must be protected against direct touch.
This you can achieve by insulation, model, position, arrangement or firmly applied devices.
The power terminals of the power module hold potential!
Essential for personal security are the safety measures and safety regulations of the DIN/VDE
standards. If protective conductor connections are missing at the appliance or at the motor
you will have to face personal damage, because the surfaces may carry dangerous voltages.
The protective conductor connection is to be carried out according to DIN EN 60204/VDE
0113 part 1; section 8.2.2 regarding also EN 50178/VDE 0160, sections 5.3.2.1 and 8.3.4.4.
Under operation there always appear discharge currents in the power module and the motor.
They are conducted by using the orderly protective conductor and can lead to premature re-
sponse of a series fault current circuit breaker.
In case of a body contact or a earth fault a direct current component can appear within the
fault current, which can complicate or keep a supervising fault current circuit breaker from re-
sponding.
Even after the action of the supply units main contactor the parts of the power module are
carrying dangerous voltages.
