• Do not use to power medical equipment.

• Not suitable as a disconnecting means.

Visit the Legrand website at www.legrand.us/radiant/smart-lighting.aspx to learn more
about your smart device.

• Do not use with loads exceeding the
device load rating (see page 22).

• Connect the smart switch to a
120 VAC, 60 Hz power source ONLY.

• Always use copper wire to install the
smart switch and follow all applicable
local and national electrical codes.

• Install in a non-metallic electrical box
to protect wireless signal strength.

installation & setup

step one | turn off the power for your device at the

circuit breaker

Flip the existing light switch multiple times to confirm the power is off.

NOTES:

• If there are multiple devices next to your existing light switch, make sure power is
off at the circuit breaker for all of those devices.

• For three-way installations using a remote switch, follow the instructions for the
remote device (WTRL20).

faqs

Q: Which wire is the “hot” wire versus the “load” wire?
A: To determine this safely, begin by confirming that power is off to the device

location at the circuit breaker. Cap all of the exposed wires in the electrical
box, then turn the power back on to the device location. Find your non­contact voltage tester. Place your voltage tester next to each of the wires.
The voltage tester should indicate which of the two wires is receiving power
from the circuit box (refer to the voltage tester’s user manual for details on
operation). The “hot” wire is the powered wire.

To safely complete your wiring, turn off power at the circuit breaker until the
device is secured into the wall.
