Enerwave ZWN-RSM2-PLUS Z-Wave Plus Dual Relay Switch Module (neutral wire required) and probably many others with the same system.
YES, these can be used in many European and other countries!!!
Not that complicated but different names and colors can be misleading.
I ordered one of these to Norway and was totally put on the wrong leg with the ‘necessity of a neutral wire’.
Checking out on the internet and on this forum did not come up with any actual solutions, but only made it more confusing.
I started searching about the possibility to connect it to ground, but quickly learned that this can be extremely dangerous.
After doing some thinking however the solution was not that difficult.
We commonly have 3 wires coming into the switch box. Either bundled in a cable like here or in the US, or as seperate wires, like amongs others in the Netherlands (where I’m from)
The colors are nowadays normalized:
Brown, Blue and Yellow/green.
The yellow/green one is earth/ground and is either not connected at all (lamps) or connected to the frame of the appliance.
Connecting the brown and the blue one will not make a difference since we are on AC (alternating current). Me myself have the relay powered by a prolonger with a EU plug (which can be rotated 180) so I don’t even know which one is what.
Normally of course it’s best to stick to the color codes.
Meaning the ‘HOT’ wire (US) should be connected to the brown one (L)
and the ‘NEUTRAL’ wire to blue (N)
The ‘LOAD’ wire is the one powering the appliance and,
the AUX is the one triggering the relay to switch.
Blue: Neutral (N)
Brown: Live (L)
Blå: Nøytral / Null (N)
Brun: Last / Fase (L)
Sort: Fase etter bryter/brudd
bruin: Fasedraad (L)
blauw: nuldraad (N)
