▶
The cable shields must be connected to the connector shell inside of the connec‐
tors. In the switch cabinet they should be connected to a ground bus.
▶
Cable shields not ending in a connector inside of the switch cabinet such as motor
cables must be connected to the ground bus.
▶
Both ends of the shield of shielded cables must generally be connected to the
shell.
The line cross-sections should be selected carefully: The maximum admissible current
should not be exceeded at the maximum ambient temperature (see technical data).
DIN VDE 0298-4 defines the admissible values for the individual line cross-sections
which must absolutely be taken into account.
The current carrying capacity in connection with the line cross-section of copper
conductors isolated with PVC or cables according to DIN VDE 0298-4 for different
types of wiring are indicated in the following table: All values are related to an ambient
temperature of +40 °C and an operating temperature at the conductor of 70 °C.
