Fronius Smart Meter 240V-3 UL Manual De Instrucciones página 33

Service
600V-3
*) The Rated VA is the maximum at 115% of nominal Vac at 50 Hz. This is the
same as the value that appears on the front label of the Fronius Smart Meter.
Maximum Power Supply Voltage Range: -20% to +15% of nominal (see table
above). For the 3D-240 service, this is -20% of 208 Vac (166 Vac) to +15% of 240
Vac (276 Vac).
Operating Frequencies: 50 / 60 Hz
Measurement Category: CAT III
Measurement category III is for measurements performed in the building install-
ation. Examples are measurements on distribution boards, circuit breakers, wir-
ing, including cables, bus bars, junction boxes, switches, socket outlets in the
fixed installation, and equipment for industrial use and some other equipment,
for example, stationary motors with permanent connection to the fixed installa-
tion.
The line voltage measurement terminals on the meter are rated for the following
CAT III voltages (these ratings appear on the front label):
Current Transformer Inputs:
Nominal Input Voltage (At CT Rated Current): 0.33333 Vac RMS
Absolute Maximum Input Voltage: 5.0 Vac RMS
Input Impedance at 50/60 Hz: 23 kOhm
