Connection examples
The examples mentioned here refer to a grid with 230 V and 50 Hz. Furthermore, the
consumers to be measured are directly connected to the ibaPQU-S system. If the values
voltage and current to be measured are higher, appropriate instrument transformers
need to be used.
Important note
The cabling always needs to be carried out by an electrician in order to guarantee elec-
trical safety.
