Here are the connection details but as Hood has said you need the manual for firmware setting the max motor current etc.etc.
Surely no one would supply a VFD without the connection and setting-up details would they ?.

But I am not sure it's any good without the VFD setup details because the default setting may enable too much current through your spindle so keep a close eye on the return water temp.

In practice the minimum connection is the 220V input, the spindle(U.V,W), the potentiometer between AM and ACM, and relay or switch between FOR and DCM

Update.

Looking at my VFD instructions - you probably don't need the potentiometer as frequency is variable from the front panel - with luck yours should be the same.
