4.8 Wiring in the ET 200pro system
Communication and auxiliary voltages are routed with standard connectors through the
interface module (or power modules) and the backplane bus to the frequency converter and
do not have to be considered here.
The power unit of the frequency 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 CE/EMC requirements are to be fulfilled, the prescribed shielded
cables must be used. For this we recommend standard SY 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
Requirements
NOTICE
National Fire Protection Association (NFPA) compatibility
These devices are only certified for installation in industrial machines in accordance with
the "Electrical Standard for Industrial Machinery" (NFPA79).
Due to their design features, it is possible that these devices cannot be installed in
accordance with the National Electrical Code (NFPA70).
NOTICE
It is only permissible to use temperature-resistant copper cables for at least 75 °C.
● Motor cable: max. 15 m, shielded with metallic HAN 8 connector
A hybrid cable is necessary when using a motor holding brake and/or PTC/KTY 84.
● Additional incoming line supply system:
– If the 400 V infeed line, 4 mm² (AWG 12), is looped through within the ET 200 station;
max. 25 A
– If a single infeed line is used for a frequency converter or motor starter, 1.5 mm²
(AWG 16) is sufficient.
