4.3.3 Isc factor (scaling factor)
In this menu, it is possible to set the Isc factor
(scaling factor) for calculating the short-circuit
current (Ik) in the functions ZI (L-N/L) and Zs
(L-PE).

The short-circuit current Ik in the power supply system is of particular importance for the
selection and testing of protective circuits (fuses, overcurrent protection devices, RCDs).
The default value of the Isc factor (Ik) is 1.00. The value has to be set according to local
requirements.
The Isc factor can be set within the range of 0.20  3.00.
4.3.4 Commander ON/OFF
In this menu, it is possible to enable or disable
the optional "Commander".
