Issue Number: 4
Table 4-13 575 V Regen system maximum cable length
Table 4-14 690 V Regen system maximum cable length
If the cable length in the above tables are exceeded, additional components are required. Refer to section 4.6.1 Available preventative measures on
page 72.
4.5.1 Cable type
Use 105 °C (221 °F) (UL 60/75 °C temp rise) PVC-insulated cable with copper conductors having a suitable voltage rating, for the following power
connections:
• AC supply to external EMC filter (when used)
• AC supply (or external EMC filter) to Regen drive
• Regen drive to motoring drive (or busbar arrangement could be used)
• Motoring drive to motor
