Nominal frequency: 50/60 Hz.
Nominal power factor: 1.
The maximum burden for current inputs is 0.1 VA, for voltage inputs - 0.1 VA. The internal
resistance of voltage inputs exceeds 4 M
Ω
.
ENIP-2 is able to continue measuring with the stated precision after influence of cur-
rent/voltage overloads specified in table 4.2.
