12.3.4 Loop resistance and prospective fault current
ThedenitionofthenominalvoltageforcalculatingI
PFC
ismodiedasfollows:
- 55 V for selection of a single-phase center-tapped network,
- 63 V for selection of a three-phase network.
The test can be carried out for both combinations (L1-PE and L2-PE). For each individual test re-
sult, the corresponding indication is shown.
Nominal input voltages:

Voltage range
single-phase network, 55 V (44V≤U≤61V)
three-phase network, 63 V (56V≤U≤70V)
If the input voltage is outside this range, this is displayed on the online voltage / terminal monitor
together with the
symbol.

Contact voltage
In compliance with EN61557-6, the measuring range for the limiting contact voltage of 25 V goes
from 3.0 V to 32.6 V.
In compliance with EN61557-6, the measuring range for the limiting contact voltage of 50 V goes
from 3.0 V to 66.0 V.
Measuring range (V) Resolution (V) Accuracy
0.0 - 9.9 0.1 (- 0 %/ + 15 % of reading + 2 digits)
