6.2.2 Mains and motor cables
The mains cables are connected to terminals L1,L2 and L3 (12-pulse units 1L1, 1L2, 1L3, 2L1, 2L2,
2L3) and the motor cables to terminals marked with U, V and W, see Figure 6-7.
In converters consisting of double input sections, an even number of input cables is required. In
converters consisting of double power modules an even number of motor cables is needed. See
tables 6-2 to 6-6 for cabling recommendations.

drives
with double inputs or outputs it
is
very important that the same cable
dimensions, type and routing is used for all cables. In case the cabling between the
converter modules is not symmetrical, unequal load might occur and reduce loadability
or even damage the converter.
In units with double motor outputs the motor cables must not be connected together in
the converter end. Always connect the parallel motor cables together in the motor end
only. The minimum motor cable length is 5m.
If a safe switch between
the
frequency converter and the motor is used, make sure that
it is switched on before setting the frequency converter in run state.
The output cables to the motor must be 360
o
EMC earthed. Separate EMC grounding clamps are
supplied with NXC FR9 if an output filter is used and with all drives of sizes FR/Fi10-12. In NXC
FR/Fi13-14, EMC grounding is implemented directly through cable glands and grounding clamps are
unnecessary. See chapter 6.2.2.1 for more information on EMC grounding for FR/Fi13-14.The EMC
grounding clamps can, for instance, be installed on the mounting plate in front of the AC choke as
shown in Figure 6-6 below. The EMC grounding clamps must be suited to the output cable diameter
to give a 360
o
contact with the cables. See chapters 6.2.6 and 6.2.7 for output cable diameters. See
Figure 6-6.
