4. Setup
Follow these steps to connect your onerbl AC-DC Adapter:
- Identify Device Port: Locate the power input port on your Leggett & Platt 50 Series Adjustable Bed or Richmat device. This port is typically labeled for DC input.
- Connect DC Output: Plug the DC output connector of the onerbl AC-DC Adapter firmly into the device's power input port.
- Connect AC Input: Attach the 2-pin AC power cord to the AC input receptacle on the adapter unit.
- Plug into Outlet: Insert the 2-pin plug of the AC power cord into a standard electrical wall outlet (100-240V AC).
- Verify Connection: Ensure all connections are secure and snug.
5. Operation
Once properly connected, the onerbl AC-DC Adapter will automatically begin supplying power to your adjustable bed or compatible device. The adapter converts the alternating current (AC) from your wall outlet into the direct current (DC) required by your device (29V 1.8A).
No further user interaction is required for the power conversion process once the adapter is connected and plugged into a live outlet.

- Cleaning: Keep the adapter unit and cords clean and free from dust. Wipe with a dry, soft cloth. Do not use liquid cleaners or abrasive materials.
- Storage: When not in use, store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.
- Cable Care: Avoid bending, twisting, or crimping the cables excessively, as this can damage the internal wiring.
