Wiring Control Circuit Terminals

Wire Sizes

For remote operation using analog signals, keep the control line length between the Analog Operator or oper-
ation signals and the Inverter to 50 m or less, and separate the lines from main power lines or other control cir-
cuits to reduce induction from peripheral devices.
When setting frequencies from an external frequency source (and not from a Digital Operator), use shielded
twisted-pair wires and ground the shield for the largest area of contact between shield and ground.
Terminal numbers and wire sizes are shown in

*1. We recommend using cable-end sleeves on signal lines to simplify wiring and to improve reliability.

*2. Refer to for tightening torques for the cable glands.
*3. Use shielded twisted-pair cables to input an external frequency reference.
