NOTES:
(1) The maximum load requirements for fluorescent, CFL and LED loads
can vary greatly depending upon the specific fixture and/or bulb being
used. These load types have significant in-rush current which can trip the
protection circuitry on the device.
(2) The quality and performance of these load types varies greatly
from manufacturer to manufacturer. When using these load types, we
recommend testing in advance. If problems are found, simply changing to
a dierent bulb manufacturer may solve the problem.
(3) Additionally, we do not recommend the use of fluorescent, CFL, or
LED loads without a neutral wire connected to the dimmer due to the
capacitive nature of these load types.
(4) Wiring with a neutral is always the preferred wiring method (if
possible).
Warnings and considerations
WARNING! Turn OFF electrical power before installing or servicing this
product. Improper use or installation can cause SERIOUS INJURY, DEATH
or LOSS/DAMAGE OF PROPERTY.
ATTENTION! Coupez l’alimentation électrique avant d’installer ou de
réparer ce produit. Une mauvaise installation ou utilisation peut entraîner
des blessures graves, décès ou perte / dommages à la propriété.
WARNING! This device must be protected by a circuit breaker (20A max).
ATTENTION! Cet appareil doit être protégé par un disjoncteur (20A max.)
WARNING! Ground this device in accordance with the National Electric
Code (NEC) requirements. DO NOT rely solely upon the yoke plate’s
contact with a metal wallbox for adequate grounding. Use the device’s
ground wire to make a secure connection to the safety ground of the
electrical system.

Specifications and supported load types
The specifications are described below.
Model numbers C4-KD120-xx, C4-KD277-xx
Power requirements C4-KD120: 120V AC +/-10%, 50/60 Hz
C4-KD277: 277V AC +/-10%, 50/60 Hz
This device can function with or without a neutral
AC connection depending on load type. Wiring
with a neutral is always the preferred wiring
method (if possible). See load types and “Sample
Wiring Configurations” below.
When wired without a neutral, loads may appear
dimmer.
Power consumption C4-KD120: 786mW; C4-KD277: 2.51W
Load types and ratings
Supported load types Incandescent, halogen, electronic (solid state)
low voltage (ELV) transformers, magnetic (iron
core, inductive) low voltage (MLV) transformers,
phase-dimmable fluorescents, compact
fluorescents, and LEDs.
Important: Do not use with non-dimmable loads.
