What do I need?
How do I get started?
The relay is designed to remotely turn on/o
lighting or power circuits (max 500W) or to
control door, window or curtain openers. You must
understand how your devices need to be wired
and how to safely turn o the electricity supply.
You will also need suitable electrical screwdrivers.
Please refer to the following installation and
setup instructions that will guide you through
the installation and setup process.
Help video & further guidance

Overview
IMPORTANT: All LightwaveRF products can be legally DIY installed in your
own home; however, if in doubt, always consult a qualified electrician or
heating engineer. It is important to install this product in accordance with
the following instructions. Failure to do so may void your warranty.

terminals. Screw cover.
Installation
The Inline relay requires mains power to operate. It can be used to provide up
to 500W of mains powered switching OR separate volts free switching for
circuits not requiring additional mains power. The relay latches between three
positions: switched live 1, switched live 2 and a neutral position (not connected).
IMPORTANT: The Inline relay is not designed to be left exposed once it is
installed, as live mains wiring is connected to the terminals. Ensure that the
device is mounted securely in a suitable housing. If conducting an insulation
resistance test, all LightwaveRF products must be disconnected from the
mains, or damage will occur.

2. Connect the live and neutral
terminals, as shown in the diagram, to
provide power to the relay. When the
green LED is illuminated, the relay is
connected to mains power.
NOTE: Even if switching a low voltage or
non-mains circuit, the relay must always
have mains power connected to the live
and neutral terminals for it to be able to
function.

IMPORTANT: When the relay is operated remotely via RF, it is always the
lefthand load terminal that will be connected when the ‘on’ button is pressed.
Therefore, if the circuit is wired as shown, pressing ‘on’ using an RF remote
will turn on the circuit, and ‘o’ will disconnect it.

2. Connect the outgoing wire ‘load’
to the leftmost load terminals ( )
as shown in the diagram. This is the
wire that will be collected to the ‘load’
(i.e. device to be switched or lamp).
The relay now has 2 positions - ‘on’
and ‘o’. The diagrams below show
the on and o positions if a live were
to be connected to the common and

Switching between two Circuits
If a second load wire connected to another circuit is attached to the second
switched live terminal (see diagram), the relay can be used to switch between
two circuits. In addition to the on and o positions, there is also a ‘stop’
position which breaks contact with both of the right and lefthand circuits.

Installation
NOTE: A standard handheld or other LightwaveRF remote control will only
be able to utilise the ‘on’ and ‘o’ commands to switch between circuits but
NOT use the stop command, as it does not include this function.
To operate the stop command you will need a LightwaveRF ‘On/O/Stop
Switch’ which includes ‘on/o’ (open/close) and ‘stop’ commands OR the
LightwaveRF App (requires Lightwave Link).
If you are using the App, you must slect the device as ‘open/close’ during
linking process (see in-app help). This will give you the ‘stop’ command as
well as on/o (open/close) when you come to operate the device from the
smartphone.
Curtains, Blinds and Doors
Because of the ‘stop’ command feature, the relay can be used to operate a
device that requires an on/o (or open/close) function AND a stop (or
pause) function, such as blinds, curtains and doors.
In this case, as before, the incoming live wire will be connected to the ‘com’
terminal, and there will be two separate outgoing ‘load’ wires each
connected to the separate switched live (or load) terminals (see diagram on
the next page).
Installation
COM L N

If the relay is being used to control
(interupt) a mains powered circuit
(max 500W load), then power
must be taken from the relay’s
main live terminal via a jumper
connection to the common
terminal (see diagram).
The neutral terminal must now also
accommodate an incoming and
outgoing connection to the mains
circuit.
COM L N

NOTE: Because of the extra ‘stop’
command, a LightwaveRF ‘On
/o/stop Switch’ or the
LightwaveRF App and Lightwave
Link will be required to operate this
setup.
