Figure 12.2: Example of voltage and frequency measurements
Displayed results for a single-phase system:
L1-L2 voltage between external conductors,
L1-PE voltage between external conductor 1 and protective conductor,
L2-PE voltage between external conductor 2 and protective conductor.
12.3.2 FI/RCD testing
The normal maximum FI/RCD testing current is 1 A RMS (peak current 1.4 A) and can only be
reached,ifthefaultloopresistanceisbelow1Ω.
Tests are carried out automatically for both combinations (L1-PE and L2-PE).
For each individual test result, the corresponding indication is shown.

12.3.3 Line resistance and prospective short-circuit current
The measured resistance represents the phase-to-phase resistance (R
L1-L2
). The nominal voltage
for calculating I
PSC
is set to 110 V.
The nominal voltage range for measuring the line resistance is 90 V to 121 V. If the input voltage
is outside this range, this is displayed on the online voltage/ terminal monitor together with the
symbol.
