Here are some images I just took of a SwitchLinc installation, the same applies for all others such as Keylincs, Icons Relays, Dimmers etc.
Like the manual you have to identify your Neutral, Hot or Line, and your Load.
The cables on the switchlinc are clearly identified. with labels and by color,
White = Neutral
Black = Line or HOT
Red = Load
Bare = Ground.
I ALWAYS turn off the breaker and make sure non of the switches im working on work. I’ve gotten many zaps as a kid and there not fun.
Before I start I make sure I write down the address, this way Im not looking for it and removing work already done.,
Also make sure the switch is setup the upwards, the address should be on the bottom left side (At least for the switchlincs and Icons). Icon switches will have their LED on the left side of the switch.
Below is a picture of the device connected
To Identify the cables I usually look for the big bundle of for Neutral and the Load. If its the first Insteon device you plug in you will see that neutrals not connected to any switch.
For example you can see the Neutrals are all together in the white bundle with the Red Cap, The load or Hot is usually another bundle of black cables (This is what provides power to all switches so usually all the blacks to/from the switches die here
And the load (Which is off to the light is usually alone or going out. is the one towards the light fixture. In this case its a black wire.
The ground is the bare cable ground, that’s a easy one.
Here is a image of the finished product, this is
2 ICON Dimmers, one regular Decora on/off switch and a Switchlinc, and a unfinished painted wall.
Here is another 4 gang which is 1 Icon, a Switchlinc Dimmer, regular switch and another SwitchLinc
