Coordinate the cable exit with the artwork
The shortest electrical route is not always the cleanest visual route. Cable exits should relate to letter positions, backing edges, wall cavities and access from inside the building.
For individual letters, a mounting rail can consolidate wiring. For a contoured neon backing, a planned exit near a stroke or fixing point can reduce visible cable length.
Keep power supplies accessible
Drivers and controllers require ventilation and eventual service access. Concealing them permanently behind a closed wall may create a maintenance problem. Agree an accessible cabinet, ceiling void, service hatch or internal position before finishes are complete.
- Confirm voltage and circuit availability
- Define driver and controller location
- Check dimming or RGB control requirements
- Document access after handover
Match fixings to the actual substrate
Concrete, masonry, cladding, insulated façades and lightweight partitions require different fixings and sometimes additional substructure. A mounting drawing should identify both visible positions and hidden load paths.
Frequently asked questions
Where should the power supply for an LED sign be installed?
In a ventilated, accessible position protected for the environment. The exact location depends on the wall build-up, cable route and service strategy.
Can cables be completely hidden?
Often yes, especially when cable exits and wall routes are prepared before installation. Existing finished surfaces may limit what can be concealed without additional work.
