6.1.1 Cabling
Use cables with heat resistance of at least +60°C. The cables and the fuses must be dimensioned
according to the frequency converter nominal input current which you can find on the rating plate.
Installation of cables according to UL regulations is presented in Chapter 6.1.3.
Table 6-1 shows the minimum dimensions of the Cu-cables and the corresponding GG/GL fuse
sizes. The dimensions of the fuses in the table have been given taking their function as a cable
overload protection into account.
If the motor temperature protection of the drive (see the Application Manual) is used as an overload
protection, the cable shall be chosen accordingly.
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.
Mains cable Power cable intended for fixed installation and
the specific mains voltage. Shielded cable not
required.
(NKCABLES/MCMK or similar recommended)
Motor cable Power cable equipped with concentric protection
wire and intended for the specific mains voltage.
(NKCABLES /MCMK or similar recommended).
OR: If EN61800-3 1
st
environment is required, a
cable with low-impedance shield.
Control cable Screened cable equipped with compact low-
impedance shield (NKCABLES /jamak,
SAB/ÖZCuY-O or similar).
