(3) Connection of two or more inverters
Factory Automation can be applied to several inverters which share a link system as
CC-Link remote device stations and are controlled and monitored by PLC user
programs.

Wiring method
1) 1) Use twisted cables (three wire type) after stripping the cable sheaths and twisting
the wires. If the sheath is stripped too long, the cable may contact with the adjacent
cable, causing a short circuit. If the sheath is stripped too short, the cable may be
disconnected. Use the recommended cables. For the specifications and availability
of the CC-Link dedicated cable, refer to the CC-Link catalog.
