11.5 Connection between SE-24 and mains adapter
▪ Use cable with a cross section large enough to reduce “ground bouncing” in
the intermediate circuit power supply.
2.5 mm² (AWG13) should be sufficient for a cable length of up to 5 m between
the mains adapter and the SE-24.
▪
Use a star shaped cabling when a number of SE-24s are connected to the
mains adapter. The star point of the reference potential should be as close to
the mains adapter as possible.
▪
The mains adapter should be fitted with a Y capacitor of at least 100 nF
between the intermediate circuit voltage and PE as well as between GND and
PE.
▪ Ensure a “good” PE connection between the mains adapter and the SE-24. It
is important to have a good refeed of the high frequency leakage current,
generated by the chopper in the SE-24 in combination with the winding
capacity between the motor phase and the PE in the motor.
▪
In order to ensure that the limit values for the emitted radiation are not
exceeded a shielded cable should be used.
NOTE
A “good” PE connection has a small impedance even at high
interference frequencies.
CAUTION
For safety reasons, all PE conductors must be connected before
commissioning.
The EN 50178 regulations for the protective earthing must be
complied with during installation.
