Cross-sections of round conductors
The standard values of the cross-section of round copper conductors as well as the ap-
proximate ratio of metric ISO and AWG/MCM values are shown in the following table.
Standardized cross-sections of round conductors:

Note
The line corresponds to a value when the connection possibilities are taken into account.
10.2.1 Motor Cable
DANGER
Dangerous shock currents
connect the motor housing to the ground of the machine or
connect the ground terminal of the motor connector to the central ground
point of the machine.
→ Consider the following with regard to shielding: Always use shielded
motor cables.
