7. Installation – 115 / 230 VAC Models
⚠️ Safety First
Installation must be performed by qualified personnel in accordance with all local and national codes.
Step-by-Step Wiring
- Lock out and verify power is OFF
- Open power supply cover
- Connect AC Line and Neutral to AC IN terminals
- Verify ground connection (internal & external lugs)
- Replace cover and tighten locking screw
- Apply power and confirm LED illumination
Bold red callout:
Do NOT connect AC input to DC output — permanent damage will occur.
8. Installation – 24VDC Barrier-Driven Models

9. Bracket Installation
Universal Bracket
- Pre-assemble brackets on illuminator
- Align with second bolt from gauge end
- Wrap cable above gauge bolts
- Tighten lower bracket first, then top
✔ Fits gauges up to 4.375 in (111 mm) wide
Alternate & Reflex Brackets
- Clear “When to use this bracket” callouts
- One diagram per step
- Red “Gauge must be out of service” warning for Reflex gauges
10. Maintenance Routine Cleaning
- Clean glass window with damp cloth only
- Do not spray cleaners directly on unit
- Never use abrasives or metal tools
Fuse Replacement
