SwitchLinc V2 Relay User’s Guide 

 Installing SwitchLinc Relay 

1.  For best INSTEON Network performance, be sure you have properly installed at least two SignaLinc 

RF Signal Enhancers. 

2.  At the circuit breaker or fuse panel, disconnect the power for 

all

 of the circuits in the switch junction 

box.  Verify that power is off by trying to turn on the lights controlled by the switches. 

3.  Remove the faceplate from the switch junction box, then unscrew the switch you are replacing and 

pull it out from the junction box. 

4.  Disconnect the wires from the switch you are replacing.  If the wires cannot be detached by 

unscrewing them, cut the wires where they enter the switch, then strip ½” of insulation off the ends. 

5.  If you are installing SwitchLinc Relay into a standard 

two-way circuit

 (where only one switch controls 

the load), follow the diagram below to identify and connect the LINE, LOAD, NEUTRAL, and 
GROUND wires.  If the colors of the wires do not match the diagram, be sure you have identified the 
wires correctly before connecting them. 

6.  If you are installing SwitchLinc Relay into a 

multi-way circuit

 (where more than one switch controls 

the same load), follow the instructions in the section 

Installing SwitchLinc Relay in a Multi-Way 

Circuit

, below, to identify and connect the LINE, TRAVELER, NEUTRAL, and GROUND wires.

NOTE 

The NEUTRAL wire will not
normally be connected to the
switch you are replacing.  If there is
no NEUTRAL wire in the junction
box (SwitchLinc Relay 

will not

function 

without a neutral), please

consult an electrician or call

7.  After you have connected all of the wires, ensure that all of the wire connectors are firmly attached 

and that there is no exposed copper except for the GROUND wire. 

8.  Orient SwitchLinc Relay with the LED Bar at the left, gently place it into the junction box, then screw it 

into place. 

9.  Turn the circuit breaker back on or re-install the fuse. 

10. After the bottom LED in the LED Bar comes on, test that SwitchLinc Relay is working properly by 

turning the light on and off. 

11.  Reinstall the faceplate.
