Identify Switch Type
Before you install DIN Rail behind a switch, you must determine which type of switch you have—latching (the default
setting), single momentary or dual momentary—as each is wired differently. If you are using DIN Rail with a single
momentary or dual momentary switch, you will program it for the corresponding switch after installation.
• Latching (default mode): switch has no central position: it can be pressed on both the top and bottom and
remains in that state once released
• Single momentary: switch can only be pressed in one place (like a doorbell) and returns to central position
once released
• Dual momentary: switch can be pressed on both the top and bottom; returns to central position once
released
Installation
1) Turn off breaker/fuse and verify power is off
2) Disconnect wires from light fixture. Strip away wire coating until you have 5/16” (8mm) of bare wire on the ends.
3) After ensuring the wires are not touching, turn on breaker/fuse
4) Use a voltage meter to identify the fixture’s line, load and neutral wires, then turn off breaker/fuse again
5) For reference, write down the INSTEON I.D. (on the side of the module) and the load it is controlling
6) Snap module onto DIN rail. (If installing next to another module, allow 3/4" (2 cm) between modules for heat
dissipation.)
7) Connect wires per diagram which corresponds to your installation
Note: sense lines carry very low current (~0.35mA 240V, ~0.17mA for 120V)
8) After ensuring wires are firmly connected and that there is no exposed wire, turn on breaker/fuse
After a few seconds, load will turn on and DIN Rail LED will turn green
9) Test by tapping DIN Rail paddle top and bottom
Load will turn on and off
DIN Rail LED will turn green when load is on and red when load is off
