Mono phase application:
Connect CT according to following drawings. Terminals phase 2 and phase 3 are opened.
Image 4.4 Mono phase application
IMPORTANT: It is necessary to ensure that potential difference between current COM terminal and
power supply “-” terminal is maximally ± 2 V. There are 2 options how to ensure this:
"Red" option - properly ground both terminals
"Blue" option - interconnect these two terminals
Always apply only one option. Never realize both options on one installation.
Voltage measurement MRS wiring
There are 4 voltage measurement Connection Type (setpoint Connection type (page 177) [3Ph4Wire
/3Ph3Wire / Split Ph / Mono Ph]) options, every type matches to corresponding generator connection type.
Note: For fusing of voltage measurement input use T1A or T2A fuse.
The generator protections are evaluated from different voltages based on Connection type (page 177) setting:
3Ph 4W – Ph-Ph voltage, Ph-N voltage
3Ph 3W – Ph-Ph voltage
SplPhL1L2 – Ph-N voltage
SplPhL1L3 – Ph-N voltage
Mono Ph – Ph-N voltage
