6.1.1 Cabling

Use cables with heat resistance of at least +70
according to the tables below. Installation of cables according to UL regulations is presented in Chapter
6.1.4.
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 information.
