1. The Inverter must be commissioned for the application before even attempting to activate
the KHP function.
2. The application, for which the Inverter has been commissioned, must be tested to ensure
that all parameter settings functioning correctly.
3. Using parameter p7763, you must set the number of parameters that can be included in
the exception list. The maximum number of parameters that can be included in this list is
