Inverter
(See note)
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.
H Wire Size and Solderless Terminals
Use thick wires to prevent voltage drops if the wires are long.

D Solderless Terminals for Control Circuit Terminals
The use of solderless terminals for the control circuit terminals is recommended because solderless
terminals are easy to connect securely.
