5.1 Voltage, frequency and phase sequence

Voltage and frequency measurement is always active in the terminal voltage monitor. In
the special VOLTAGE TRMS menu the measured voltage, frequency and information
about detected three-phase connection can be stored. Phase sequence measurement
conforms to the EN 61557-7 standard.
See chapter 4.1 Function selection for instructions on
key functionality.
