12.2.3 Parameters for Grid Monitoring
PFAbsMin** Limitation of the
displacement
power factor cos φ 0.5 … 1 ‒ 0.9
Q-EnaTmsVtg* Connection delay
of line voltage Off ‒ Off
On ‒
* This parameter can only be changed after the installer password has been entered.
** This is a read‑only parameter.
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.
