GE 45613 GE Z-Wave 3-Way Dimmer Kit with flying leads - Manual (Page 9)

IMPORTANT NOTE ABOUT 3-WAY CIRCUITS CONT.
The yellow wire from the 45607 must only be connected to
the yellow wire of the 45610 via the traveler wire. The dimmer
switch will fail if the yellow wire is connected to Line (Hot),
Neutral or Ground. It must be insulated properly if it is not used.
Please consult an electrician if you have trouble identifying the
type of wiring circuit you wish to convert or if you do not feel
confident in your ability to convert the circuit to Z-Wave control.
INSTALLATION
This dimmer switch is designed for use with permanently
installed incandescent lighting only and may be used in new
installations or to replace an existing wall switch. A wall plate
is not included. You may be able to re-use your existing wall
plate if you are replacing a standard decorator style switch
or dimmer. If this is a new installation or your existing wall
plate can not be used, we recommend the use of a mid-sized,
decorator style wall plate. These are available at most home
centers or hardware stores.
It can be used by itself or in three-way installations where a
light is controlled from 2 locations such as the top and bottom
of a staircase. It is also compatible with four-way installations
(three switches & one light) if a second auxiliary switch is used.
Please note: The 45610 Auxiliary Switch must be used with the
45607 Dimmer Switch in three-way installations. Two Auxiliary
switches must be used in four-way installations.
