HI

I HAVE A DANFOSS VLT INVERTER ,

240volt input 220 volt 3 phase variable frequency output

I came off a Myford Vertical Mill and is

installed in a large electrical housing box.

It is TYPE DANFOSS VLT 2020 195H 3104 - Without a display.

Unfortunately I do not have an Instruction Manual and cannot find one.

Can anyone help locate a wiring instructions/ diagram please.

I Need to change the rotation of the spindle, I know i can do it on the 3 phases,

but i would like to add a switchable forward/ reverse unit to the inverter 

see photos below

Thank you in advance

Try **LINK**. The model without display seems to be a weirdo, see about p.33 et seq.

The way I read the diagram on page 10 of Dick's link, connecting Terminal 19 to 24v (output on Terminal 12) will reverse the motor. The diagram shows this done with a switch where ON is reverse and OFF is forward.
