Coil Note) Connect so that polarity is matched to the connector’s (+), (.) and A, B and COM indicators. In case of voltage specifications other than 12 or 24 VDC, take care to avoid mistaking polarity, as there is no diode to prevent reverse current. In the event that lead wires are connected in advance, they will be as shown below. Pos. common specifications A (.): Black COM (+): Red B (.): White (No lead wire in case of single solenoid) Neg. common specifications A (+): Black COM (.): Yellow B (+): White (No lead wire in case of single solenoid) Light Indication Changing the Connector Entry Direction Caution When equipped with indicator light and surge voltage suppressor, the light window turns orange when solenoid A is energized, and it turns green when solenoid B is energized. Solenoid A Solenoid B Light A: Orange B: Green Caution To change the connector’s entry direction, press the levers on both sides of the connector, take it off, and change the direction as shown in the drawing. Since lead wires are attached to the connector, excessive pulling or twisting can cause broken wires or other trouble. Also, take care that lead wires are not pinched when installing the connector. If an excessive force is applied on the connector in the LOCK position, the connector block may be damaged. Also, using in such a way that the connector floats in the FREE position, it may cause the lead wire, etc. to break. Thus, refrain from using in these ways.
