Additional requirements placed on the protective conductor
①
:
●
For permanent connection, 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-conductor cable using an industrial plug connector according to
EN 60309, the protective conductor must have a cross-section of
≥
2.5 mm² Cu.

Wiring the ET200pro system
Overview
Communication and auxiliary voltages are routed with standard connectors through the
interface module (or power modules) and the backplane bus to the converter and do not
have to be considered here.
The converter is rated for direct operation on TN and TT line supply systems with a
grounded PEN conductor with a rated voltage of 3 AC 400 V. In the case of systems where
EMC requirements are to be fulfilled, the prescribed shielded cables must be used. For this
we recommend standard CY cables; the shield must be grounded at both ends and the
perfect connection of the shielding must be checked.
The 400 V supply is connected using standard connectors:
●
X1 line supply system input
●
X2 motor connector (the cables for both the brake and the temperature sensor are
integrated)
●
X3 looped-through line supply system
