Important Notes

Please read before installing.

1. CAUTION:

 Use dimmer model “Q-” only with permanently

installed 120V incandescent or halogen fixtures. To avoid
overheating and possible damage to other equipment, do not use
to control receptacles, fluorescent lighting fixtures, motor-driven
appliances, or transformer-supplied appliances. Use dimmer
model “QLV-” only with core and coil (magnetic) low-voltage
transformers. To control solid state (electronic) low-voltage
transformers, use Lutron electronic low-voltage dimmers.

2. CAUTION:

 Operating magnetic low-voltage fixtures with all lamps

inoperative or removed may result in current flow in excess of
normal levels. To avoid possible transformer overheating and
premature failure, Lutron strongly recommends the following:
• Replace burned-out lamps immediately.
• Use magnetic low-voltage fixtures with thermal protection or

fused primary windings to prevent transformer failure due to
excess current.

3.

When no “ground means” exists within the wallbox, then NEC

®

2002 404-9 exception to (b) allows a dimmer without a ground
connection, to be installed as a replacement. A dimmer installed
under this exception (NEC

®

 2002 404-9 exception to (b)) must be

provided with a plastic, noncombustible, UL listed wallplate.
