Cable and fuse specifications
Use cables with heat resistance of at least 158 °F (70 °C). The cables and
the fuses must be dimensioned according to the tables below.
Installation of cables is presented in chapter „3.10
on page 32.
The fuses function also as cable overload protection. The recommended
fuse types are gG/gL (IEC 60269-1). 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 what is recommended below should not be

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.
Honeywell offers recommendations also for aR (IEC 60269-4)
and gS (IEC 60269-4) fuse ranges.
These instructions apply only to cases with one motor and one cable con-
nection from the frequency converter to the motor. In any other case, ask
the factory for more information.
