Note Use a transformer with 200- and 400-V outputs for the power supply of the 400-V Inverter.
2-2-5 Wiring Control Circuit Terminals
A control signal line must be 50 m maximum and separated from power lines. The fre-
quency reference must be input to the Inverter through twisted-pair wires.

Considerations When Wiring Control Circuit Terminals
•
Wire control signal lines separately from the main circuit lines and other power lines.
•
Wire control circuit terminals 9, 10, 18, 19, and 20 (contact outputs) separately from terminals 1 to 8,
21, 22, 23, 25, 26, 27, 33, and 11 to 17.
•
Connect shielded wire to terminal 12(G).
•
Insulate the shielded areas with tape to prevent contact with other signal lines and equipment.
