I've got a client in the food processing/production industry that has purchase some European equipment. He has recently acquired a Sifter with a WEG 21 motor.
I'm not familiar with these European motors. This motor appears to be wired for 480v as is, but would like to verify for sure.

Thank you

First thing:
Is the motor intended for use in Europe or USA?
For Europe it will will be 50Hz,, 400V.
 
Take care: the wiring diagram does not necessarily show the proper connection graphically. If I read the wiring diagram correctly, there are 12 motor leads but only 9 terminals. In different connections different pairs of leads will share the same terminals. So you need to read the labels on the leads to be sure.

I agree it's wired for "Hi-Voltage" as is.

It is very common for European motors to come strapped for Hi-Voltage by default. It's a no brainer and the safest choice, less chance of letting the smoke out accidentally.

During deployment of a fleet of sorting machines I worked on 10 years ago, we did convince Lenze (Germany) to strap our motors for Lo-Voltage since there were hundreds and hundreds of motors and we did not want to be opening every cover and making mistakes while commissioning. When we fired up machines, I'd occasionally get a call from the field that a vertical lift was having problems going up and would trip out with a Servo Following error. I asked does it go down OK? If the answer was yes, it was almost always a simple mistake by Lenze where they let one sneak thru strapped for Hi-Voltage.
