Wiring Diagram Ground terminal Common terminals Ground terminal 1 .In the case of a double solenoid valve, a common terminal is provided to simplify wiring. When the common terminal is not used, remove the terminal screws. 2.Use the ground terminal when grounding is required. 3.In the case of a solderless terminal, M3 screws. 4.Tighten terminal screws to a torque of 0.5 to 0.7Nm {5.1 to Electrical Circuit Diagram
