3.8 Supply system cable and motor cable
3.8.1 Supply system cable
Dimensioning of the supply system cable generally takes place plant-specifically and
depends on the design of the line connection. Line connection is shown in the chapter
"Power connection"(→2271). Observe the country-specific and plant-specific regula-
tions when selecting the cross section of the supply system cable.
Recommended cross section for nominal operation
The cross section of the supply system cables must be dimensioned based on the
nominal line current I
line
.
SEW‑EURODRIVE suggests the cable cross sections listed in the table. Cables with
these cross sections can be used if the following conditions are met:
• The single-pole cables are made of copper with PVC insulation.
• The cables are routed in cable ducts according to IEC60204-1 installation type C
at 40°C ambient temperature.

INFORMATION
Recommended cross section
The values are only recommendations. They are no substitute for detailed project
planning of the cables depending on the concrete application and considering the ap-
plicable regulations.
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.
