5 POWER CABLING
5.1 CABLE DIMENSIONING AND SELECTION
5.1.1 CABLE AND FUSE SIZES, IEC
We recommend the fuse type gG/gL (IEC 60269-1) for mains fuses (-F1). Use only fuses that
have a sufficient voltage rating according to the mains voltage. Do not use larger fuses than
what is recommended in Table 7. The fuses are selected for short circuit protection only.
NOTE!
The overcurrent protection of parallel cables must be done with separate fuses.
Make sure that the operation time of the fuse is less than 0.4 seconds. The operation time
agrees with the fuse type and the impedance of the supply circuit.
The table also shows the typical symmetrically shielded copper and aluminum types of the
cables that can be used with the AC drive.
NOTE!
The mains cable and fuse sizes are valid up to a cable length of 100 m, with mains

The drive should be protected with fast acting aR-type fuses (-FC1) (see Table 9, Table 10,
Table 11 and Table 12). Do not use other fuses than these. These fuses are included in the
delivery.
