*) 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 installation.
Examples are measurements on distribution boards, circuit breakers, wiring, 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 installation.
The line voltage measurement terminals on the meter are rated for the following CAT III
voltages (these ratings appear on the front label):
