Power Connections

DC Supply and Motor Cables
The power cables are connected to terminals DC+ and DC- (R+/B+ and DC terminals when
using an external charging circuit) and the motor cables to terminals U, V and W. A cable
entry gland should be used at the motor cable end to reach the EMC levels, see Table 3-2.
Use cables with a heat resistance of at least +60C. The cables and the fuses must be sized
according to the inverter nominal output current which you can find on the rating plate.
Installation of cables according to UL regulations is presented on Page 3-17 and aR fuse sizes
in Tables 3-2 and 3-3 below.
If the motor temperature protection of the drive is used as an overload protection, the cable
shall be chosen accordingly. If three or more cables are used in parallel for bigger units, each
cable requires a separate overload protection.
These instructions apply only to installations with one motor and one cable connection from
the inverter to the motor. In any other case, ask the factory for more information.
