4.2.3 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 according
to UL regulations is presented in Chapter 4.2.6.
The fuses function also as cable overload protection.
These instructions apply only to cases with one motor and one cable connection from
the frequency converter to the motor. In any other case, ask the factory for more in-
formation.
