3.4.2 Connection on control section
The 11-terminal control terminal block is a plug-in block and is located on the
front.

The control cables should be screened and twisted. The screening is applied
on one side in the proximity of the frequency inverter (PES).

Alternatively, in addition to the broad area gland plate, you can also twist the
screen braid at the end and connect to the protective earth with a cable lug.
To prevent EMC disturbance, this twisted shielding connection should be
made as short as possible ( Figure 39, page 68).
Prevent the screen from becoming unbraided at the other end of the control
cable, e.g. by using a rubber grommet. The shield braid must not make any
connection with the protective ground here because this would cause prob-
lems with an interference loop.

Prevent the screening from becoming unbraided, i.e. by
pushing
the
separated
plastic covering over the end of the shielding or
with a rubber grommet on the end of the screening.
