5.4.1 Dimensioning of conductor cross-section
The cable dimensions should be selected according to the current load and voltage
drop to be expected. Select the cable cross-section of the cables such that the voltage
drop is as small as possible. If the voltage drop is too great, the motor will not reach
its full torque. Also comply with any additional national and application-specific regula-
tions and the separate UL instructions. For typical mains fuses, refer to chapter
“Technical Data”.
Note: According to EN61800-5-1, the cross sections of the PE conductor shall be
dimensioned as follows:
Mains cable Protective conductor
Mains cable up to 10 mm² Install two protective conductors of
the same size as the mains cable, or
one protective conductor of a size of
10 mm².
Mains cable 10…16 mm² Install one protective conductor of the
same size as the mains cable.
Mains cable 16…35 mm² Install one protective conductor of a
size of 16 mm²
Mains cable > 35 mm² Install one protective conductor of half
the size of the mains cable.
5.4.1.1 Typical cross-sections
The following tables provide an overview of typical cable cross-sections (copper cable
with PVC insulation, 30 °C ambient temperature, continuous mains current max.
100% rated input current). Actual mains cable cross-section requirements may de-
viate from these values due to actual operating conditions.
230 V: One-phase (L/N) and two-phase (L1/L2) connection
