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 3-17and aR fuse sizes in Tables 3-2and 3-3below.

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.
