Note
You should take the following points into consideration when connecting the
device to the three-phase network to be measured:
- Energy flow direction
Assigning measuring voltage input / current transformer input
Rotary field:
As soon as the multicount 3D6-0-LCD-EP-.../3D6-1-LCD-ES-...c is connected to the mains, it will auto-
matically detect the rotary direction.
Current transformation connection:
Energy flow direction:
When mounting the transformers, observe the current flow or energy flow direction. If the current transformers
are inserted the wrong way, the current will have a negative sign for active power input. In this case,
interchange the pins of the terminals k and I of the affected transformers.
Assigning measuring voltage input / current transformer input:
The current transformer on terminal 20/21 (k1/l1) must be arranged in the phase where the measuring voltage
for the terminal 10 (L1) is measured. The same applies to the other transformer and measuring voltage con-
nections.

Caution
Before any interchanging the transformers must be shorted out!
