AC 240V motor connections

I have a new motor that looks somewhat different from the old one and unfortunately did not come with a wiring diagram. When I pop open the little cover plate on the motor, I see 4 terminals for sliding crimp-on connectors on. They are sort of grouped by 2. The two terminals on top have a ground screw nearby, the two below don't. I'm running 10 gauge 2 wire with ground, so what goes where? Again, this a a 240 motor. Thanks for any info.

Question

Not enough info.....
Give everything on the motor plate.
Is there a capacitor? Is it external?

A new-to-you motor, or a NEW motor? If "new," I'd be calling the manufacturer and demanding the wiring diagram.

The only thing I can add to Mac and Steves reply is... dont guess. You are wrong and you will let the smoke out of your motor. There should be a connection diagram...possibly for low and high voltage. These diagrams are almost always on the nameplate or the "in" side of the wiring connection (peckerhead) cover.
As Mac said is this a new in box motor or just another motor you resourcefully came up with?

Ringing out a motor is not a DIY project. You either need to get the proper wiring from the mfg, or carry the motor to a rewind shop and have them ring it out for you.

As roger already said, if you get this wrong, you will burn the motor up.

thank you, I'll contact emerson

Just looked again. 2 capacitors and they are both wired. The two bottom prongs are really a one piece terminal, while the top ones, where the ground screw is, are separate. Anyway, sound advice, it's just that Emerson don't make it easy with online diagrams. I guess there's no shortcut this time
