Wiring Precautions
l
CM and 5G terminals are insulated to each other. Do not connect these terminals with each other and do not
connect these terminals to the power ground. Terminal 5G is indicated as CM from 30kW inverters and has the
same potential as CM (Sequence Common Terminal).
l
Use shielded wires or twisted wires for control circuit wiring, and separate these wires from the main power circuits
and other high voltage circuits.
l
It is recommended to use the cables of 1.25
mm
²
(22 AWG) for connection to the control circuit terminals.
n
Control Circuit Terminal
l
The control input terminal of the control circuit is ON when the circuit is configured to the current flows out of the
terminal, as shown in the following illustration. CM terminal is the common terminal for the contact input signals.
CAUTION
Do not apply voltage to any control input terminals (FX, RX, P1, P2, P3, JOG, BX, RST, CM).
