Setup and Installation
- Prepare Mounting Hole: Drill a 22mm (7/8 inch) diameter hole in your panel. Ensure the panel thickness does not exceed 6mm (0.24 inches).
- Insert Indicator Light: Insert the indicator light into the drilled hole from the front of the panel.
- Secure with Locking Nut: Thread the panel locking nut onto the indicator light from the back of the panel and tighten it securely to hold the light in place.
- Wiring Connections:
- The indicator light uses screw-clamp terminals for electrical connections.
- Connect your AC/DC 12V power supply wires to these terminals. The indicator light is non-polarized, meaning the connection order of positive and negative wires does not affect its function.
- Ensure wires are stripped to an appropriate length and inserted fully into the terminals before tightening the screws. Avoid over-tightening, as this may damage the terminal mechanism.
- Note that the depth behind the panel is 37mm. Ensure adequate space for wiring and connections, especially in confined enclosures.
- Install Dust Cap: If applicable, snap the dust cap onto the rear of the indicator light to protect the terminals from dust and debris.
Operating Instructions
Once properly installed and wired, the uxcell Red Indicator Light will illuminate when power (AC/DC 12V) is supplied to its terminals. The LED will emit a steady red light, indicating the status of the circuit or equipment it is connected to.

Maintenance
- Periodically inspect the indicator light for any physical damage or loose connections.
- Clean the lens with a soft, dry cloth if dust or dirt accumulates, ensuring clear visibility. Do not use abrasive cleaners.
- Ensure the dust cap (if installed) remains securely in place to protect the wiring terminals.
Troubleshooting
- Indicator Light Does Not Illuminate:
- Verify that the power supply (AC/DC 12V) is active and correctly connected to the indicator light terminals.
- Check for loose or faulty wiring connections. Re-secure any loose wires.
- Ensure the voltage supplied matches the product's specification (12V).
- Inspect the LED for any visible damage.
- Intermittent Illumination:
- Check for loose wiring connections at the terminals or within the circuit.
- Ensure stable power supply.
