Installation
CAUTIONS AND WARNINGS
Read and understand these instructions before installing and retain them for future reference.
This product is intended for installation in accordance with the National Electric Code and local regulations in the United States or
the Canadian Electrical Code and local regulations in Canada. Use indoors only. This product is not designed or approved for use
on power lines other than single-phase voltages between 100 – 277VAC, 50/60Hz., single phase. Attempting to use this product on
non-approved power lines may have hazardous consequences.
Recommended installation practices:
• Use only indoors or in an outdoor rated box
• Be sure that you have turned off the circuit breaker or removed the fuse for the circuit you are installing this product into.
Installing this product with the power on will expose you to dangerous voltages.
• Connect using only copper or copper-clad wire
• This product may feel warm during operation. The amount of heat generated is within approved limits and poses no hazards.
To minimize heat buildup, ensure the area surrounding the rear of this product is as clear of clutter as possible.
• To reduce the risk of overheating and possible damage to other equipment, do not use this product to control Loads in excess
of the specified maximum(s) or, install in locations with electricity specifications which are outside of the product’s
specifications. If this device supports dimming, please note that dimming an inductive Load, such as a fan or transformer,
could cause damage to the dimmer, the load bearing device, or both. If the manufacturer of the load device does not
recommend dimming, use a non-dimming INSTEON on/off switch. USER ASSUMES ALL RISKS ASSOCIATED WITH
DIMMING AN INDUCTIVE LOAD.
Identifying the Electrical Wires in your Home
• Line - usually Black, may also be called HOT, LIVE or Power, carries 100 - 277VAC electricity into the wall box
• Neutral - usually White commonly daisy chained from box to box usually appearing as a White wire bundle
• Load – usually Black, Blue, or Red (from a separate cable jacket)
• Ground - Bare wire or metal fixture (if grounded)
IMPORTANT!
• Each INSTEON product is assigned a unique INSTEON ID, which is printed on the product’s label. Please take note for future
reference
• If you have any difficulties or questions, consult an electrician. If you are not knowledgeable about, and comfortable with
Tools Needed
• Slotted screwdriver • Phillips screwdriver
• Wire cutter / stripper • Voltage Meter

1) Turn off circuit breaker(s) or remove fuse(s) feeding wall box
2) Use a voltage meter to verify that power is off
3) Remove wallplate from the switch and unscrew switch you are replacing and gently pull out
4) Disconnect wires from switch
5) Turn breaker(s) back on
6) Use a voltage meter to identify Line and Load
wires which connected to the switch
7) Identify Neutral and Ground wires
8) Turn breakers(s) back off
9) Connect wires as per Table A/Fig. 1(confirm firm
attachment with no exposed wire)
10) Gently place SwitchLinc into wall box, orienting
unit with the LED bar on left. Then, screw
SwitchLinc into place.
11) Turn breaker(s) back on
SwitchLinc’s LED bar and connected
light will turn on
12) Verify SwitchLinc is working properly by tapping SwitchLinc’s paddle turning light (load) on and off

Installation – Circuit with 2 Switches (3-way)
Circuits with 2 switches are called 3-way circuits. Both switches in a 3-way circuit need to be replaced by
SwitchLincs (and/or KeypadLincs).
Note: 3-way circuits require a pair of wires called Travelers between joining wall boxes to operate.
INSTEON switches, dimmers and keypads do not require both Traveler wires for 3-way circuits to
function. Simply wire one to Line, Neutral and Load; the other(s) to Line and Neutral. Use one Traveler to
share Line between boxes. Adding both SwitchLincs to a Scene creates a virtual 3-way circuit.
1) Turn off circuit breaker(s) and/or remove fuse(s) feeding wall boxes
2) Use a voltage meter to verify that power is off
3) Pull both switches from their wall boxes, each existing 3-way switch will have no less than 3 wires
4) Remove wires from existing switches
5) Make sure wires are safely separated from each other and turn breaker(s) back on
6) Using a voltage meter measure each wire to Ground in both boxes until you find the single wire
supplying 100 - 277VAC (Line)
a. We will now refer to that location as box 1
b. The other box will have the Load wire. That will be box 2
7) Turn breaker(s) back off
In Box 1 (Line box)
8) Connect bare Ground wire f r om the
SwitchLinc to bare Ground wire or Ground
screw in wall box
9) Connect White Neutral wire from SwitchLinc
to Neutral wire(s) in wa ll b o x (us ually white)
10) Using a wire nut, cap the Red wire from
SwitchLinc
11) Connect Black wire from Switch Linc to 100 277VAC Line wire in wall box (usuall y Black)
along with one Traveler wire running between
boxes (preferabl y Black) . Note color of
Traveler you are using as this will carry Line
voltage to box 2.
12) Cap unused Traveler
In Box 2 (Load box)
13) Connect bare Ground wire from
SwitchLinc to bare Ground wire or
Ground screw in wall box
14) Connect White Neutral wire from
SwitchLinc to Neutral wire(s) in wall
box (usually White)
15) Connect Red wire from SwitchLinc to
Load wire (usually Black)
16) Connect Black wire from SwitchLinc to
same color Traveler from box 1
carrying 100 - 277VAC Line (usually
Black)
17) Cap unused Traveler wire
18) With the LED bar on the left, gently
place both SwitchLincs into the
junction boxes and screw in place
19) Turn breaker(s) On
