DIMMER SELECTION
Electronic low-voltage dimmers using reverse-phase dimming are strongly preferred (e.g. Lutron NTELV
Lutron Vierti VTELV). This type of dimmer will produce the best low-end dimming effects (dimmable to 1%) and will
make the ballast silent during dimming.
Forward-phase low-voltage magnetic dimmers may also be used (e.g. Lutron NTLV), however low-end dimming
performance will be comprimised (luminiares will only dim to 20%) and ballast noise may be audible during
dimming.
CIRCUITING NOTES
Connection cable ratings: #14 AWG, maximum allowable current for this cable is 12 amps.
DO NOT EXCEED MAXIMUM NUMBER OF LUMINAIRES PER CIRUIT.
Branch circuit requirements:
SYSTEM CHECKLIST (PRIOR TO ENERGIZING)
The circuit may be energized after the following items have been completed:
A. Luminaires are properly fastened and lamps are properly installed and seated within the lampholders.
B. All electrical connections between luminaires have been mated properly.
C. Cable straps have been properly installed.
TROUBLESHOOTING
Lamp will not light.
The ballast in this luminaire is equipped with integral open-circuit and ground-fault protection. If the luminaire is
energized without a lamp in place, the ballast will turn itself off automatically. To reset the ballast, the primary
power must be turned off, and then on again. If the luminaire still does not light, the lamp could be inoperable.
Contact the factory for further assistance.
Lamp exhibits a rolling or spiraling effect
Turn the luminaire off for five seconds, and then turn on for two seconds. Repeat this procedure 5-10 times. The
rolling or spiraling should stop. If the lamp continues to roll or spiral, remove the lamp from the luminaire, wipe it
with a clean rag, and reinsert the lamp. If the lamp continues to appear unstable, contact the factory for further
assistance.
