Screened cables must be used for all of the motor– and line supply feeder ca-
bles. A covered metal cable duct which is connected through the largest possi-
ble surface area, can alternatively be used. In both cases, it should be ensured
that the shield/cable duct are connected through the largest possible surface
area to the appropriate components (converter module, motor).
Note
If the system is subject to a high–voltage test using an AC voltage, a line filter
must be disconnected in order to achieve a correct test result.
All of the cable shields must be connected as close as possible to the particular
terminal point through the largest possible surface area; for components which
do not have a special shield connection, e.g. using the appropriate clamps or
serrated rail on the bare cabinet mounting panel. The length of the cable bet-
ween the screen connection point and the terminal must be kept as short as
possible.
Screen connecting plates are available on the NE– and power modules to con-
nect the screens of screened power cables. These connecting plates have
clamp connections and mounting points for brake terminals (Order No., refer to
Table 10-1. Also refer to the dimension drawing ”EMC measures” Section 13).

If the motor is equipped with a brake, then the screen of the brake feeder cable
must be connected at both ends with the screen of the power cable.
If there is no way of connecting the shield at the motor side, then a gland must
be provided in the terminal box which allows the shield to be connected through
the largest possible surface area (e. g. UNI IRIS DICHT U71.Pg from the
PFLITSCH company).

Warning
Cable shields and unused cores in power cables (e. g. braking conductors)
must be connected to PE potential in order to discharge capacitive cross–coup-
ling charge effects.
If this is not observed, lethal contact voltages can occur, i.e. the voltages could
cause serious injury or death.
