Note: This 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 meter.
Maximum Power Supply Voltage Range: -20% to +15% of nominal (see table above). For the
WNB-3D-240-P, 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 volt-
ages (these ratings also appear on the front label):
