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.

NOTE:

 Because of the extra ‘stop’ 

command, a LightwaveRF ‘On
