Install the Nano Switch.

Nano Switch installs behind a lighting switch or a momentary push button. It works with only 3-wire (with neutral) lighting setups, though each installation of Nano Switch is accordingly slightly different:

1. Shut off the main circuit breaker of your home for safety during the installation and ensure the wires are not short circuited during the installation which will cause damage to the Nano Switch.

Note: Your home’s main circuit breaker must support the overload protection for safety.

2. Preparing connection wires

14 AWG power wires for Input / Output.

18 AWG copper wires for external manual switch.

Use the wire stripper cut the metallic part of the connection wire and make sure the length of the metallic part is about 5mm.

Note: All connection wires needs to be flexible cable.

Wiring diagram of 120/230VAC power input.

In some cases, you may have some loads just only can be used on the voltage of 24VDC and hope that it still can be controlled by the Nano Switch, so please refer to the following diagram to achieve this:

Wiring diagram of 120/230VAC power input connection to 24VDC power output.

(Compatible to Nano Switch without Energy Reading [ZW139] only).

Note: The “IN” terminal should be connected to the “-” of 24VDC input.

Warning: Nano Switch ZW116 is not compatible with this configuration, you must use Nano Switch ZW139 without energy reading.

Wiring diagram of 24VDC power input.

Since the Nano Switch also supports the 24VDC power input, so you can use it to control the loads that powered by 24VDC.

If the output loads should be only powered by AC120V or AC230V, you can change the wire connection as below:
