Chapter 4 - Power Cabling
The line voltage cables are connected to terminals L1, L2 and L3 and the motor
cables to terminals marked with U, V and W. See the following figure. See Table
Cable Types Required to Meet Standards for the cable recommendations for
different EMC levels.
Figure 12: Connection Diagram.
Use cables with heat resistance of at least +70°C (158°F). The cables and the
fuses must be sized according to the drive nominal OUTPUT current found on the
nameplate.
