4.4 Cable dimensioning and selection
Table 12 shows the minimum dimensions of the Cu-cables and the corresponding fuse sizes.
These instructions apply only to cases with one motor and one cable connection from the AC drive
to the motor. In any other case, ask the factory for more information.
4.4.1 Cable and fuse sizes, frames MM4 to MM6
The recommended fuse types are gG/gL (IEC 60269-1) or class T (UL & CSA). The fuse voltage rating
should be selected according to the supply network. The final selection should be made according
to local regulations, cable installation conditions and cable specification. Bigger fuses than those
recommended below shall not be used.
Check that the fuse operating time is less than 0.4 seconds. Operating time depends on used fuse
type and impedance of the supply circuit. Consult the factory about faster fuses. VACON

also rec-
ommends high speed J (UL & CSA), aR (UL recognized, IEC 60269-4) and gS (IEC 60269-4) fuse
ranges.
Table 12. Cable and fuse sizes for VACON

100 X.
The terminal sizes are intended for 1 conductor. For MM6, the max. diameter of the ring terminal is 14 mm.
The cable dimensioning is based on the criteria of the International Standard IEC60364-5-52: Cables must be
PVC-isolated; Max number of parallel cables is 9.
When using cables in parallel,
NOTE HOWEVER that the requirements of both the cross-sectional area and
the max number of cables must be observed.
For important information on the requirements of the earthing conductor, see chapter Earthing and earth
fault protection of the standard.
For the correction factors for each temperature, see International Standard IEC60364-5-52.
