5.5 3-phase measurement in 4-wire system
5.5.1 Direct connection
Note
3-phase measurements in 3-wire systems are only possible via a
star point adapter (creates neutral point) plugged into the voltage
inputs.
 Ensure that there is no overload at the current input of the
power analyzer.
 If there is a potential risk of overload at the current input,
incorporate a shunt or transducer into the circuit.
 If necessary, install appropriate fuses.
