The following should be noted in connection with the measurement setup:
- The grounded line conductor must be determined with certainty.
- The grounded line conductor is connected to the N connection of the
I/O module.
For example, in the following connection diagram, L2 is selected as the
grounded line conductor.
- The two other line conductors are connected to voltage measurement inputs
L1 and L3.
- Voltage measurement input L2 is not connected.
- The current transformers are connected according to the order of the line
conductors on the voltage side (for example, L2 is the grounded line conductor
in the following connection diagram).
