Converting Balder Motor

[Angelfire]

Hiya Folks,
I have a Baldor motor that I am planning to convert from 120v to 240V. I'm not near the motor until later this week so I'll have a peek under the electrical cover to see if they have a diagram but in the meantime, when I search Baldor's site for the model number, I find a wiring table:



All good so far until I see the last column. For 240V, I'm using the "HIGH" line items and in the last column it indicates to Join "J". Can anyone clarify what I join "J" to? "J" is defined further on their diagram as being brown and tying into the Thermal Overload at point 2:



Given I haven't physically looked it over, it's quite possible there are two J wires which would seem to indicate I wire these together but unsure of this

Thanks much for any insight!
Cheers.

the J wire is left unconnected.

Thank you. That wasn't an option I considered given it was in a "join" column!

Why would you leave the thermal overload unconnected? Good way to burn up the motor

OP what size in HP is this motor? Do you have a motor starter? What is it used on?

Ask ABB

It’s a 1 hp farm duty motor. Here’s a link to the whole wiring diagram from their site: https://www.baldor.com/api/products/FDL3510M/drawings/CD0269

I haven’t opened it up to verify but I don’t believe a starter is present. This is being used on a log splitter

Cheers

Has 3 wires on the thermal. One is line in. The others are one for each winding when on 120v. When wired 240v the windings are in series, total current is 1/2 this allows the thermal to still work

When you connect 4, the thermal overload is in line with that line. You done need to connect J to anything else
