4.4.2 Cable and fuse sizes, frames MM4 to MM6, North America
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.

100 X.
The cable dimensioning is based on the criteria of the Underwriters’ Laboratories UL508C:Cables must be
PVC-isolated; Max ambient temperature +40 °C (104 °F), max temperature of cable surface +70/+75 °C (158/
167 °F); 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 standard Underwriters’ Labo-
ratories UL508C.
For the correction factors for each temperature, see the instructions of standard Underwriters’ Laboratories
UL508C.
