We've got a new oven which shows a diagram requiring 3 wires for our wanted configuration. The old oven however is supplied with a 4 wire cable.
The Old oven has each wire marked as follows:
green wire - Earth
red - PH1
white - PH2
blue - N
Is it ok to just cut plus tape the white wire and only connect up the red. Or does it need to be connected somehow?
2 different configurations are shown.
Left side: 380v ac 3ph
Right side: 230v ac 1ph
We're not supplied with 380v so we can only do the right side configuration. Am I missing something here?
The model of the new oven is 310100, it has no information in its manual regarding the electrical configuration other than to follow the panel. No extra parts came with the oven.
I'm unsure of what those little brackets mean on the diagram.
The new oven supports single phase or a 3 phase connections. As Simon B and Ecnerwal pointed out the brackets show that a single wire needs to be linked through the points 1 to 3 when doing a single phase connection.
The question still is, what should I do with the white PH2 wire.
Edit 3: Got an electrician to do it. The jumpers were actually supplied. The electrician connected both the red and white wires and only used 2 of the brass jumpers.
