12.1 Overview of all Parameters
Loss of UL certification
The limiting values for the line voltage and the power frequency are configured in accordance
with IEEE 1547. Changes to the factory-configured limiting values result in the loss of UL
certification. The parameters for these limiting values are marked with ***.
• If the UL certification is the deciding factor for the operation permission of the inverter, do
not make any changes to the factory-configured limiting values for the grid monitoring
parameters.
