Table 9
Inom is the value of the measured current for a current sensor output of 1 V. See Table 23 for the nominal current values.
Pnom is the power for V = 1000 V and I = Inom.
*: The intrinsic uncertainty for input current (I) is specified for an isolated input voltage of 1 V = Inom. The intrinsic uncertainty
of the connected current sensor should be added to this intrinsic uncertainty to determine the total intrinsic uncertainty. In the
case of using sensors Amp

and Mini

, intrinsic uncertainty is given in Table 24.
The intrinsic uncertainty for neutral current is the maximum intrinsic uncertainty on I1, I2 and I3.
**: Indicative maximum value of the intrinsic uncertainty. Higher uncertainties can be noted, in particular with EMI.
