Limiting the disturbance in the motor cables will also limit mains disturbance.
Screened cables helps running both signal sensitive cables and power cables in the same raceway. When using
screened cables, 360° screening is obtained with collars directly bolted to the ground support.

The inverters of the SINUS K series may be delivered with incorporated input filters; in that case, models are
marked with A1, A2, B in the ID number.
If built-in filters are fitted, disturbance amplitude ranges between allowable emission limits (see section
NORMATIVE REFERENCES).
As for devices of group 1, class B for standard EN55011and VDE0875G, just install an additional output toroid
filter (e.g. type 2xK618) on the models with incorporated filter A1. Make sure that the three cables between the
motor and the inverter go through the core. The figure shows the wiring diagram for the line, the inverter and
the motor.

NOTE
Install the output filter near the inverter to comply with the standards in force
(leave a minimum clearance for the cable connections); follow the instructions
given for the connection of the ground terminals and the terminals of the filter,
the motor and the inverter (see section Mains).
NOTE
Install the toroid filter by leading the connection cables between the motor and
the inverter inside the toroid.
