I bought a secondhand Omron 3G3MV AB040.

I have to test the VFD as soon as it arrives, after some time waiting for the bloke to answer my email he asked me to send him an email saying I wouldn't ask for my money
back if it didn't work; which I obviously refused to do. So I need to test it
works as soon as I get it.

I haven't ever run a VFD before.
Can I just wire it up and switch it on?
Should I leave the motor wires off and switch it on and peruse the menus and set stuff prior to connecting the motor and switching on?
The motor it will be running is a Yaskawa spindle motor
Or are they well protected and fault or complain in some way if the settings are wrong?
