Wiring Control Circuit Terminals; Wire Sizes And Closed-Loop Connectors - Omron VARISPEED G7 Instruction Manual

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), used shielded
twisted-pair wires and ground the shield to terminal E (G), as shown in the following diagram.
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 Close-loop Connector Sizes 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.
