5. Setup and Installation
The installation process involves mounting the gate opener, installing the chain, and connecting the power source. Detailed step-by-step instructions are provided in the full user manual included with your product. It is recommended to have basic mechanical and electrical knowledge for installation. If unsure, consult a qualified professional.
5.1 Site Preparation
- Ensure the gate slides smoothly and is properly aligned.
- Clear any debris or obstructions from the gate path.
- Prepare a stable, level concrete pad for mounting the gate opener.
5.2 Mounting the Gate Opener
Securely fasten the gate opener unit to the prepared concrete pad using the provided mounting hardware. Ensure the unit is level and positioned correctly relative to the gate and chain path.
5.3 Chain Installation
Attach the roller chain to both ends of your sliding gate and route it through the drive sprocket of the gate opener. Adjust the chain tension to ensure smooth operation without excessive slack or tightness.
5.4 Power Connection
The DKC2000S supports multiple power configurations:

- AC Power: Connect the gate opener directly to a 110-120VAC power source.
- Solar Power: Connect the included 40W solar panels to the TCS3 solar charge controller, then connect the controller to the gate opener. This setup requires two 12V 12Ah automotive/marine batteries (not included) connected in series to provide 24VDC.
- Hybrid Power: Combine AC power with solar panels and batteries for continuous operation and backup power.
Ensure all electrical connections are secure and properly insulated.
5.5 Limit Switch Adjustment
Adjust the magnetic limit switches to define the gate's fully open and fully closed positions. This is crucial for proper gate operation and safety.
