OWER CABLING
The mains cables are connected to terminals L1, L2 and L3 and the motor cables to terminals
marked with U, V and W. See principal connection diagram in Figure 12. See also Table 13 for
the cable recommmendations for different EMC levels.

Use cables with heat resistance of at least +70°C. The cables and the fuses must be dimen-
sioned according to the drive nominal OUTPUT current which you can find on the rating plate.

1 = Power cable intended for fixed installation and the specific mains voltage. Shielded
cable not required. (MCMK or similar recommended).
2 = Symmetrical power cable equipped with concentric protection wire and intended for the
specific mains voltage. (MCMK or similar recommended). See Figure 13.
3 = Symmetrical power cable equipped with compact low-impedance shield and intended
for the specific mains voltage. [MCCMK, EMCMK or similar recommended; Recom-
mended cable transfer impedance (1...30MHz) max. 100mohm/m]. See Figure 13.
