Instructions for use and safety precautions
1 . According to the graphical operation, the AC contactor to the three-phase power line of the motor passes through the three perforations of the protector, and the phase sequence is arbitrary. The terminal of the protector is connected in series to the secondary circuit of the AC contactor. .
2 . First, turn the current regulator knob of the protector clockwise to the position of the maximum scale value. After checking the wiring is correct, start the motor and make it in normal operation. At the same time, the three-phase green luminous tube of the protector is on. The overload red indicator light is not Light, then turn the current adjustment knob slowly counter-clockwise until the overload indicator lights up. At this time, the protector is in the critical state of overload protection. Slowly turn back clockwise until the overload indicator just goes out, then the protector's The scale value of the current adjustment knob is the current value of the motor overload protection.
