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.
Figure 12. Principal connection diagram
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.
Table 13. Cable types required to meet standards
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.
