Additional requirements placed on the protective conductor of the line feeder cable:
● For permanent connections, the protective conductor must fulfill at least one of the
following conditions:
–
The protective conductor is routed so that it is protected against damage along its
complete length.
Cables routed inside electrical cabinets or enclosed machine housings are considered
to be adequately protected against mechanical damage.
– As a conductor of a multi-conductor cable, the protective conductor has a cross-
section ≥ 2.5 mm² Cu.
– For an individual conductor, the protective conductor has a cross- section ≥ 10 mm² Cu.
– The protective conductor consists of two conductors with the same cross-section.
● When connecting a multi-core cable using an industrial plug connector according to EN
60309, the protective conductor must have a cross- section of ≥ 2.5 mm² Cu.
4.2.2 Line connection
Open the terminal covers of the converter.
Connect the protective conductor of the power supply cable to terminal PE of the inverter.
Connect the power supply cable to terminals U1, V1 and W1.
When using copper busbars, the same cross-sections should be used as the connecting
busbars of the device itself:
● Frame size GX: 52 mm x 4 mm
● Frame size HX: 64 mm x 8 mm
● Frame size JX: 80 mm x 8 mm
4.2.3 Length of motor cables
With the following cable lengths, the inverters operate according to the datasheet
specifications:

For C3 applications with motor cable lengths in the range >100 m to 150 m an additional
basic interference suppression module shall be provided on the line side (available on
request).
