General Information Regarding the Wiring
▶
▶
▶
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.

For detailed information refer to the standard IEC 60364-5-52 and the documents of
the cable manufacturer.
The following correction factors are provided for deviating ambient temperatures:

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.
