Protective Cover Application
- Use a flat-head screwdriver to pry open the protective cover and wire fixing board. Disconnect the wire fixing board and connect the wires according to the wiring diagram.
- Reinstall the wire fixing board, press it down, and then snap the protective cover back into place while holding the wire fixing board with a small flat-head screwdriver.
Installation Precautions
- Do not stack products; maintain at least 15cm spacing for heat dissipation and lifespan.
- Keep products at least 15cm away from other LED drivers to ensure proper heat dissipation and lifespan.
- Ensure the installation area temperature is within the product's working range (-20°C to 50°C ambient, 80°C case). Avoid installing inside LED fixtures to prevent overheating.
Using the NFC Lighting APP
The LTSYS NFC Lighting App allows configuration of the LED driver. Scan the provided QR code to download and install the app (requires NFC-capable Android or iOS 13+ iPhone). Ensure the driver is powered off before setting parameters. To read/write driver data, open the app, select 'Read/Write LED driver', and bring the phone close to the driver's NFC logo. Users can then edit parameters like output current and dimming mode in 'Parameter settings' and write them back to the driver.
