1. Thread standard: BSPP-British Standard Pipe Parallel or NPT-National (American) Pipe Thread.

1.Connect the red wire to the positive pole and the black wire to the negative pole. The actuator will rotate counterclockwise to CLOSE the valve. 2.Connect the black wire to the positive pole and the red wire to the negative pole. The actuator will rotate clockwise to OPEN the valve. 3.Once the valve is fully opened or closed the actuator will not continue to draw power due to an internal cut off. * Rated voltage: DC12V or DC24V * Do not exceed the voltage rating.

1.Connect the red wire to the positive pole and the black wire to the negative pole. The actuator will rotate counterclockwise to CLOSE the valve. After the valve is closed, the yellow & white wires are connected, and the valve automatically stops； 2.Connect the black wire to the positive pole and the red wire to the negative pole. The actuator will rotate clockwise to OPEN the valve. After the valve is opened, the green & white wires are connected, and the valve automatically stops；

Ⅰ、Failsafe closed wiring method: 1.Red & Green wires connect to positive + 2.Black wire connects to negative - 3.When the switch is connected to the green wire, the actuator will rotate counterclockwise, closing the valve. After reaching full closed position, it will automatically stop; 4.When the switch is disconnected to the green wire, the actuator will rotate clockwise, opening the valve. After reaching full open position, it will automatically stop; If a power loss occurs the valve will automatically close. Ⅱ、Failsafe open wiring method: 1.Red & Green wires connect to positive + 2.Black wires connects to negative - 3.When the switch is connected to the green wire, the actuator will rotate counterclockwise, opening the valve. After reaching full open position, it will automatically stop; 4.When the switch is disconnected to the green wire, the actuator will rotate clockwise, closing the valve. After reaching full closed position, it will automatically stop; If a power loss occurs the valve will automatically open. Capacitor Return Fail Safe - the actuator requires a minimum energized cycles of at least 120 seconds to ensure the internal capacitor is fully charged and has enough power to close/open the valve completely. Without a minimum of 120 seconds powered the capacitor may not maintain enough power to auto return the valve to the closed/open position, the valve may result in partial or incomplete closures. * Rated voltage: DC12-24V & AC24V or AC110-230V (optional) * Do not exceed the voltage rating.
