Power Connection Specifications

  1. Low Voltage Safety: Illuminated letters operate on DC 12V or 24V low voltage; connecting to AC 110V–240V is strictly prohibited.
  2. Polarity Identification: Different colored wires represent different polarities; ensure wires of the same polarity are connected together.
  3. Transformer Connection: Connect the gathered letter wires to the low-voltage output terminal of the transformer (note the + / – poles).
  4. Insulation: Connections should be soldered or tightly twisted and must be wrapped with insulating tape.
  5. Main Power Input: Connect the （L and N) terminals of the transformer to the local mains (AC 110V–240V).

Installation Steps

  1. Positioning: Apply the 1:1 installation template to the target wall surface.
  2. Drilling: Drill holes at the marked points on the template for mounting screws and wiring.
  3. Fixing: Screw the studs into the back of the letters, align them with the holes, and secure with nuts or adhesive on the back if necessary.
  4. Wiring Loop: If the sign length exceeds 3 meters, connect both ends of the main busbar to the transformer to prevent voltage drop.

Troubleshooting

  • No Lighting: Check if the transformer indicator is on, or swap the polarity of the output wires.
  • Partial Lighting: Check if the polarity of the non-illuminated letters is reversed.
  • Flickering: Check for short circuits or if the transformer is overloaded.

CRITICAL WARNING: NEVER connect the signage directly to the high-voltage main power!
