Wiring Control Terminals

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