Recommended cross section
The cross section of the supply system cable and the selection of the fuse can be dimensioned based on the nominal line current IN of the power supply module at nominal load PN. Alternatively, dimensioning can be based on the configured permanent line current. This can be found in the SEW-Workbench.
If dimensioning is to be based on the nominal power, SEW-EURODRIVE suggests the following cable cross sections. These cable cross sections apply under the following conditions:
- The conductors are made of copper with PVC insulation, operating temperature 70 °C.
- The cables are routed according to IEC 60204-1 installation type C at an ambient temperature of 40 °C, accumulation 1.

INFORMATION
Securing the supply system cable
- Secure the supply system cable with appropriate safety elements.
- When selecting the supply system cable, make sure that the selected cross section is in the range of the connectable cross section of the terminals.
- When selecting the line fuse, observe chapter Line fuses and miniature circuit breakers.
