To suppress occurrence of interference, toroidal cores must be mounted in
the motor leads and in the voltage supply lead if you are using
non-regenerative compact inverters. If you are using the UE 21x, you must
also integrate toroidal cores in the lead to the braking resistor.

The 50-line ribbon cable connects the UE 2xxB or UR 2xx to the control and is
responsible for the power supply. It is supplied with the compact inverter
(length 300 mm, ID 325 816-01).
The 20-line ribbon cable connects the PWM outputs of the control with the
PWM connections on the compact inverter. One 20-line ribbon cable is
required for each axis/spindle. The 20-line ribbon cables for the connections on
the compact inverter are supplied with the compact inverter (length 200 mm,
ID 250 479-08; length 400 mm, ID 250 479-10). If you are using an additional
UM 111D power module, you will need an additional 20-line ribbon cable:

The 40-line ribbon cable serves as the unit bus. It is required if an additional
UM 111 D power module is being operated with the compact inverter.
