Connection on control section
The control signal terminals are arranged under the frontal cover
flap.
The cable hold down clamps contained in the scope of delivery can
be mounted on the cable clamp plate of the power section.
The control lines should be shielded and twisted. The shielding is
exposed on one side (PES), on the cable hold down clamps on the
frequency inverter for instance.
Prevent the shielding 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 shielding.
As an alternative, in addition to a broad area cable clip, you can
also twist the shielding braid at the end and connect to protective
ground with a cable clip. To prevent EMC disturbance, this twisted
shielding connection should be made as short as possible (see
figure 32 on page 39.).
On the other end of the control line, you should prevent any
unraveling with a rubber grommet. The shielding braid is not to
make any connection with protective ground here because this
would cause problems with an interference loop.
