Mono phase application
Connect CT according to following drawings. Terminals phase 2 and phase 3 are opened.
Image 4.9 Mono phase application
IMPORTANT: It is necessary to ensure that potential difference between current COM terminal
and power supply "–" terminal is maximally ±2 V. To do so ground properly both terminals.
Image 4.10 Mono phase application
IMPORTANT: It is necessary to ensure that potential difference between current COM terminal
and power supply "–" terminal is maximally ±2V. To do so interconnect these two terminals.
Note: This wiring is recommended for Indian market.
Voltage measurement AMF wiring
There are 6 voltage measurement Connection Type (setpoint Connection type (page 209) [3Ph4Wire / High
Leg D / 3Ph3Wire / SplPhL1L2 / SplPhL1L3 / Mono Ph] options, each 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 209)
setting:
3Ph 4W – Ph-Ph voltage, Ph-N voltage
High Leg D – Ph-Ph voltage, Ph-N voltage
