3.6 Connection of the
Control Lines
Notes:
– The shield from the digital signal lines, which is not connected via terminals,
must be clamped to the screen bus, both at the cabinet entrance and near the
inverter, in order to decrease the screen impedance.
– If digital signal lines are connected via terminals, the screen must be clamped
to the screen bus before and after the terminals.
– If a screen bus is used near the inverter ( max 20 cm distance ), then the
screen no longer needs to be connected to the inverter.
– If the shield is earthed with a single charger, then the interference derivation
deteriorates by 70%.
– Metal copper pipe clips are suitable as a shield connection.
– When using non-shielded signal lines, they should always be installed as a
twisted pair with a forward and return circuit.
CE marked frequency inverter and servo drives were developed and manufactured
to comply with the regulations of the Low-Voltage Directive 73/23/EEC.
The applied standards are listed in the technical documentation part 2.
A manufacturer declaration in accordance with 89/392 EEC can be provided by
KEB if needed.
