Project Planning
6.10.3 Line protection and core cross section
Comply with the regulations of the specific country and for the specific machine
regarding fusing and selecting . If required, also adhere to the notes on
UL compliant
installation
.
Always size the shared neutral conductor for the total current when using several single-
phase units. Also size it according to the total current even if the unit connections are
distributed over the three mains phases. This is because the third supply current
harmonics are always cumulative.
Select the cable cross section of the motor so the voltage drop is as small as possible.
An excessively high voltage drop means that the full motor torque is not achieved.
Smallest bending
space (EN 61800-
5-1)
As stipulated in EN 61800-5-1, the distance between a power connection terminal and
an obstruction toward which the wire is directed on leaving the terminal must correspond
with the minimum values given in the table below.
Recommendation
for standard instal-
lation, metric
If single-core copper cables with PVC insulation routed in cable ducts are used, SEW-
EURODRIVE proposes the following cable cross-sections and fuses for an ambient
temperature of 25 °C and rated mains currents of 100% of the rated inverter current:
