Help wiring cooker hood for cafe

[HLR Electrical]

I think we've sussed the fan - the control switch selects one of four lines for the speed required. What the OP is stuck on now is how to wire a 4-position camswitch for 1P4W.

With the switch being marked 0-3, one speed (e.g. minimum) will have to be unused. It is likely to be something like:

White (speed 1) park in a Wago.
Red (speed 2) to switch terminal 1
Grey (speed 3) to switch terminal 3
Black (speed 4) to switch terminal 5
Blue (N) to incoming supply N.
Switch terminal 2 to incoming supply L
If they are not internally linked, it will be necessary to link terminals 2, 4 & 6 to extend the line to the other two contact sets.

Please check all of this with your meter before connecting up!!

Thankyou for your help, you have been very useful to me.

But check this carefully as I have made some assumptions such as the switch marking conventions. Check that in position 1, only 1-2 is closed, and in position 2, only 3-4 etc. Check that the four lines are in increasing order of resistance to N. Better still, keep looking for the proper MI's.

Wont 1 need connecting to allow 4 speeds?

 

[Lucien Nunes]

Apparently the OP's switch only has 0-1-2-3

 

[Lucien Nunes]

BTW, if the switch has another pole closed in all positions other than 0, that's for the neutral.

Suggestion of opening the connection cover is due to that being a popular location for wiring diagrams

Also something to consider;
2 of the wires may well be for the thermal cutout.

don't tell that to my consultant.he'll want to open my skull to see how my brain is wired.

And also what about overload protection? imo you need it

As soon as you open the cover it will all become clear..
The numbers on the terminals will correspond with those on the wiring diagram for the selector switch

 

[Lucien Nunes]

According to the MI's, thermal overload protection is incorporated, and this is marked on the label on the OP's own unit (TOP). They also show the speed selector switch wired directly to the supply. About the only info they don't give is the wire colours. Presumably the switch is not supplied by EBM but by the hood makers.
