To operate the TECHTOP TD20 Series inverter at a remote location, use an external keypad with parameter copy functionality. Connect the external keypad to the VFD and configure AI1 settings. Ensure that the external keypad AI1 is set correctly and adjust the local potentiometer AI1 to 0V/0mA before starting the VFD if the external keypad AI1 is the frequency reference source. The keypad will display different states, including stopping, running, function code editing, and fault alarm.
