8.3.6 Pin 13 PRO (Enable firmware programming)
The programming of the wrong firmware can lead to the damage of the inverter!
The programming may only be carried out after consultation with the company BRUSA Elektronik
AG!
This pin is only activated for the programming of a new firmware (Pin PRO = high). Pin 3 EN must
also be high for this.
In normal operation, this pin may not be wired or it must be directly connected with terminal 31. An
open circuit can lead to a reset of the inverter!
As soon as Pin 13 PRO is high, the following processes are triggered:
The inverter is stopped (reset) if it is in operation.
The programming can now be carried out via the serial interface.
