4.4 Cable dimensioning and selection
Table 17 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 MS2 to MS3
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 specifications. 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 recommends high speed J (UL & CSA), aR (UL recognized, IEC 60269-4) and gS (IEC
60269-4) fuse ranges.
Table 17. Cable and fuse sizes for
VACON
®
20 CP.
The cable dimensioning is based on the criteria of the International Standard IEC60364-5-52 : Cables
must be PVC-isolated; use only cables with concentric copper shield; 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 .
