)-0/24!.4 Voltage sensing burden is < 1VA per phase.
4)0 For all wiring configurations, the minimum voltage sensing threshold is
2V AC typical. Maximum voltage withstand limit is 360V AC. These limits
are provided for reference only. Metering accuracy applies only when
operating in the range specified for voltage and frequency in the table
above for the specified wiring configuration.
