What's the stroke length, retracted length and extended length? How to install Prepare to connect the two wires of the actuator to a 12 volt battery Red wire to the positive terminal and black wire to negative terminal will make the actuator extend. To make it retract, just reverse the terminal connections. To simplify the last step, you can prepare a reverse polarity relay or switch for the actuator. When you want the actuator to extend and retract, just press the switch. Your actuator will hold its position when the power is off. It will automatically stop when reaches the end. The actuator has pre-installed inner limit switch, it cannot be adjustable. How to protect your actuator ​Please use the 12V DC power adapter The actual load does not exceed the rated load All the actuators have duty cycle, they are unable to work all the time without stop. The duty cycle of this actuator is 20%. it means that your actuator needs 4 minutes to rest for every 1 minute of work. If the actuator keeps working for long time, the motor is easily burnt out. Please be careful, the actuator not completely waterproof What you will get ​1pc SOViK Heavy Duty Linear Actuator Professional after-sale service Used for Window Opener for your Greenhouse or the Tall Building Simple operation to avoid manual work and dangerous.
