Wiring Control Circuit Terminals
Wire Sizes and Closed-loop Connectors
For remote operation using analog signals, keep the control line length between the Digital Operator or opera-
tion signals and the Inverter to 50 m or less, and separate the lines from high-power lines (main circuits or
relay sequence circuits) to reduce induction from peripheral devices.
When setting frequencies from an external frequency setter (and not from a Digital Operator), use shielded
twisted-pair wires and ground the shield to terminal E (G), as shown in the following diagram.
Fig 2.14
Terminal numbers and wire sizes are shown in Table 2.9.
* 1. Use shielded twisted-pair cables to input an external frequency reference.
*2.Refer to Table 2.3 Closed-loop Crimp Terminal and Insulation Cap Sizes (200 V Class and 400 V Class) for suitable closed-loop crimp terminal sizes
for the wires.
* 3. We recommend using straight solderless terminal on signal lines to simplify wiring and improve reliability.
