Conflicting ID numbers

If the ID numbers of the line-side and the motor-side converters are set equal, the
control panel stops functioning. To clear the situation:

• Set the ID number of the line-side converter RMIO board to 2. For the setting
procedure, see the inverter control program (e.g. Pump Control Program)
Firmware Manual.
