Further information about measurement limits are at setpoint CT Ratio [/5A] description in chapter
Setpoints - Basic Settings.
Generator currents and power measurement is suppressed if current level is bellow <1% of CT
range.
To ensure proper function:
Use cables of 2,5mm
2
Use transformers to 5A
Connect CT according to following drawings:
Three phase application:
It is necessary to ensure that potential difference between generator current COM terminal and
battery “-” terminal is maximally ± 2V. Therefore is strongly recommended to interconnect
these two terminals together.
Single phase application:
Connect CT according to following drawings. Terminals L2l and L3l are opened.
