6.1.1 General Cable Requirements
Use cables with a minimum heat resistance of +70 °C (158 °F). In the selection of the cables and the fuses, refer to the nominal output
current of the drive. Find the nominal output current on the nameplate.
We recommend selecting the cables and the fuses to agree with the output current because the input current of the AC drive is almost
the same as the output current.
For information on how to make the cable installation to comply with the UL standards, see 6.1.2 UL Standards on Cabling .
If the motor temperature protection of the drive (see VACON
®
All in One Application Manual) is used as an overload protection, select
the cable to agree with the protection. If 3 or more cables are used in parallel for larger AC drives, use a separate overload protection
for each cable.
