* Power Modules with Class B integrated filters, frame sizes A to C, must be fitted with a ferrite ring on the motor cable
between the Power Module power terminals and the shielding plates of the Power Module to fulfill EMC category C1 condi-
tions. Only use copper wire Class 1 75 °C (for compliance with UL).
Power Modules with integrated Class B filters, frame sizes B and C, in addition to the ferrite ring on the motor cable, must
also have a ferrite ring on the line supply cable.
CAUTION
Control cables must be laid separately from the power cables. The connection must be
carried out as shown in the installation section in this manual, to prevent inductive and
capacitive interference from influencing the correct system function.
Note
Ensure that the appropriate circuit breakers or fuses with the specified current rating are
connected between the power supply and the inverter. The technical specifications contain
information about the circuit-breaker and the fuses. See the technical specifications.
EMC cable glands
To ensure compliance with the relevant EMC standards, all communication and I/O cables of
the Control Unit must be routed through a gland plate. EMC-compliant cable glands must be
used.
CAUTION
Conformity of the radiated emission
For the PM230 Power Modules, frame sizes A to C, an EMC cable gland MUST be used for
the motor cables, which is in compliance with the current standards regarding radiated
emissions.
