Wiring Control Circuit Terminals

Wire Sizes

For remote operation using analog signals, the control line length between the Analog Operator or operation
signals and the Inverter should be less than 30 m. The controller wires should always be separated from main
power lines or other control circuits in order to avoid disturbances.
It is recommended to use shielded twisted-pair wires and ground the shield for the largest area of contact
between shield and ground.
The terminal numbers and the appropriate wire sizes are shown in
