wiring a dol

[Thermo]

Can you just confirm that the coil within the contactor is rated at 240v and not 415v?

if youre talking about the dol then yes its rated at 240v. its this one here

N feed to 1L1
Link 2T1 to 3L2
L feed to 5L3
N load to 4T2
L load to 6T3
Connect the two floating black conductors together.

thank you very very much. All comments greatly appreciated chaps, ill return the compliment if youre ever in teh gardening section


sorry is that a typo on the l feed, shouldnt it be 5L3 and not 3L3?

would need to be 5L3

not sure about the blacks as can not see where they connect and if there are others also.
Is there a drawing inside the cover of the unit

Yes, and now corrected.

Gary, can you see a neutral for the coil.

 

[GaryMo]

It'll be the link leaving 1L1.

 

[Thermo]

Is there a drawing inside the cover of the unit

No the instructions state, wire up as old one....so none of it much help really!

 

[333rocky333]

I think i can see the neutral link now.
If so it goes from 1L1 to the coil (possibly terminal A2)
The reason N feed needs to go in 1L1.

The two blacks look like the wires to the seperate over load unit which would go in series with the control.
As you do not have one, join together as gary said or replace with one wire.

 

[Thermo]

so all as per garys instructions re what goes where then

 

[GaryMo]

Yes

It looks to me that the moter has thermal protection built in but to comply, any motor over 370W should have electrical overload protection too. It will fix to the load side of the contactor [DOL starter] and the wiring for 2T1, 4T2, 6T3 will be on the corresponding connexions of the overload instead of the contactor. The 2 black wires will then go one each to the NC terminals of the overload instead of being joined.

I will strongly recommend that you fit the overload.

If you are not intending to fit a thermal overload there is no point in the link in the above, it will probably be easier to understand too.
N feed to 1L1
Link deleted
L feed to 5L3
N load to 2T1
L load to 6T3

Ideally there should also be an emergency stop button, It will be wired in series with the red button, ie in between the 2 floating black wires.

if i fit an overload, what size do i need from this list

[mikhailfaradayski]

do you see what i mean now?

Has anything gone 'bang' yet?

 

[GaryMo]

What rating is the planer in amps (A)?
