Applications
- Lighting systems requiring 100% to 10% fluorescent dimming.
- EcoSystem digital-link lighting control installations.
- 3-wire phase-control applications using compatible Lutron controls.
- Installations using daylight sensors, occupancy sensors, wallstations, or IR receivers.
- 2-lamp F54T5 fluorescent fixtures.
Installation Tips
- The ballast and fixture must be grounded for proper dimming.
- Turn the supply breaker OFF before wiring the ballast, EcoSystem digital link, or connected sensors.
- For T5 lamps, ballast-to-lamp socket wiring must not exceed 7 ft (2 m).
- Mount T5 and T5HO lamps 1/16 in to 3/8 in (1.6 mm to 9.5 mm) away from the grounded metal surface.
- Lamps must never touch the ground plane and should be installed without obstruction.
- Keep Class 1 and Class 2 wiring separate and follow all applicable national and local electrical codes.
- Class 2 sensor terminals accept only one 22 AWG (0.25 mm²) solid conductor per terminal.
- Power wiring, lamp wiring, and EcoSystem digital link terminals accept only one 16 or 18 AWG (0.75 or 1.5 mm²) solid conductor per terminal.
