Motor cables are sources of inter-
ference. This means that you
must use shielded cables in order
to meet the corresponding elec-
tromagnetic compatibility specifi-
cations. The cable lengths that are
actually possible depend on the
following:
‒ Operating environment
‒ Converter being used
‒ Reactors and filters used
‒ Shielded or unshielded cable
In order to meet Class A / C2 elec-
tromagnetic compatibility requi-
rements, you need a power
module with integrated filter and
a shielded cable (max. length:
25 meters). To meet Class B / C1,
a Power Module with Filter B has
to be used (IP55 max. 25m, IP20
max. 50m).

A star connection is shown in the
1 example. The rating plate provides
information about the correct
circuit data: e.g. 230/400 V ∆/Y
means that you operate the motor
in a Y connection with a 400 V
line supply.
