Wire Sizes
For remote operation using analog signals, keep the control line length between the Analog Operator or operation
signals and the Inverter to 30 m or less, and separate the lines from main power lines or other control circuits
to reduce induction from peripheral devices.
When setting frequencies from an external frequency source (and not from a Digital Operator/Monitor), used
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 Table 2.8.

* 1. Use shielded twisted-pair cables to input an external frequency reference.
* 2. Refer to Table 2.3 for suitable lug sizes for the wires.
* 3. We recommend using straight solderless terminal on signal lines to simplify wiring and improve reliability.
