I agree with the comments above - these instructions are not clear. I’m upgrading an existing printer with a new Duet2 WiFi. Like Fabio the fans in the printer have 3 wires (+5V, - and signal). Is it OK to connect the +5V and - wires to the fan pins, and leave the signal wire unconnected? Or do I need to get new fans? I also agree with Rob - the instructions should explicitly call out the need to properly set the jumper to match the voltage of the fans being used. Had I not seen Rob’s comment I too would have blown my 5V fans.
