2-6 Wiring of control terminals
Please refer to the table 2-6-1 for the function of control terminals. According to different
function setting, the function and connection of the control terminals will be different.

If need remote control, we suggest using (two wires) control mode, please refer to 2-8 in Page 8
(two wires control mode).
Usually, the contact signal input terminal and common terminal will do close/open (ON/OFF)
actions, the soft starter, motor and conductor arrangement will produce interference, therefore,
please use shorter wire (shorter than 20m), and use shielding conductor for cable.
The conductor arrangement of control terminal should be far away from the wiring of main
circuit. Otherwise, there may be error operation caused by interference.
