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 2.27
Terminal
numbers and wire sizes are shown in Table 2.19.
* 1. Use
shielded twisted-pair cables to input an external frequency reference.
* 2. Refer
to Table 2.9 Close-loop Connector Sizes (JIS C2805) (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.
