When I want register. I enter all data and I scan 14 digit from the inverter. I receive a message saying: “please enter 14 or 18 digits of letters and number only” and I cannot register after many trials.
The error message suggests that the program requires either a 14 or 18-digit combination of letters and numbers for registration. If you are entering the 14-digit number from the inverter and it is not being accepted, it might be worth double-checking if there are any letters included in the code and ensuring it matches the required format.
