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 designed for direct operation on TN and TT line
supply systems with a grounded neutral conductor with a rated voltage of 3 AC 400 V. In the
case of systems where CE-EMC requirements are to be fulfilled, the specified shielded
cables must be used. For this we recommend standard SY cables; the shield must be
grounded at both ends and the shield must be perfectly connected.
The 400 V supply is connected using standard plug connectors:
● X1 line supply infeed
● X2 motor plug connector (the cables for both the brake and the temperature sensor are
integrated)
● X3 looped-through line supply
Requirements
Note
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).
Note
It is only permissible to use temperature-resistant copper cables rated 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:
–
If the 400 V line infeed, 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.
