• When using more than one Inverter, be careful not to loop the ground wire.
3-2-3 Wiring Control Circuit Terminals
The control signal line must be 50 m or less and must be separated from the power line.
Use batch shielded cable for sequence input. If frequency references are input
externally, use a twisted-pair shielded line.
H Wiring Sequence Input/Output Terminals
Wire the sequence input terminals (SF, SR, S1 to S3, and SC), multi-function contact output terminals
(MA, MB, and MC), and multi-function photocoupler output terminals (PA and PC) as described below.
