2-2-5 Wiring Control Circuit Terminals

A control signal line must be 50 m maximum and separated from power
lines.
The frequency reference must be input into the Inverter through shielded,
twisted-pair wires.
Wiring Sequence I/O Terminals
Wire the sequence input terminals (S1 to S5 and SC) and multi-function contact output
terminals (MA, MB, and MC) as described below.
