10.1.3 Cable and Fuses
By means of this section you can check whether you can still optimize your machine
with regard to the material usage. The specifications are derived from the DIN VDE
0298 Part 4. The values apply approximately and only for the intended operation. In
border cases always proceed in accordance with the above standard. The following
table shows the current-carrying capacity of 3- and/or 5-wire PVC cables (i.e. 2 and/or
3 loaded wires) in dependence on the ambient temperature. The current is to be laid
out to the input current of the frequency inverter.

Current in [A] atCross section of feed cable
The use of special cables or the way of laying the cables allows even higher currents
(see DIN VDE 0298 Part 4). The motor cable must correspond to the cross-section of
the mains cable.
If in the case of long lines (>30m) still maximum torque is required at the motor shaft,
the cable should be dimensioned for the next larger cross-section in order to reduce
line resistances.
Mains fuses are to be designed for the rated input current of the inverter. The current/
time-characteristic of the fuse must be slow-acting in order to avoid premature tripping
when utilizing the power reserves of the inverter.
