2.2.5 Control Circuit Terminals
Symbol Terminal Name Function
M1~M4
Multi-functional digital
input terminals
Do not connect additional power source
directly.
A digital input is ON when it is connected to
GND, and will be OFF when it is opened.
Action current is 10mA.
GND Ground terminal Zero potential of +10V and +24V
MO1

external sensor.
2.2.5 Precautions for Connecting Control Circuit Terminals
It is necessary to use shielded cable and twisted pair cable well-grounded (inverter
side). The cable should be more than 20cm away from power electricity cables and
conductors. Do not run the control cable paralleling to power electricity cables, try
vertically.
