4.4.5 Z factor
In this menu Z correction factor for limit of
maximum Line / Loop impedance can be
set.
Figure 4.9: Selection of Z factor
Keys:
UP / DOWN
Sets Z factor value.
TEST
Confirms Z factor value.
ESC
Exits back to settings menu.
Function selectors
Exits back to main menu without changes.
Maximum impedance in the supply system is important for selection or verification of
protective circuit breakers (fuses, over-current breaking devices, RCDs).
