3. METER DESCRIPTION
3.1. Current inputs
All current inputs are galvanically isolated (internal current transformers).
The meter is adapted to co-operate with external measuring current
transformers.
Displayed current values and derived quantities are automatically
re-counted by the quantity of the introduced external transformer ratio.
Current inputs are defined in the order as 1 A or 5 A.
3.2. Voltage inputs
Quantities on voltage inputs are automatically recounted by the quantitiy
of the introduced external voltage transformer ratio.
Voltage inputs are defined in the order as 3 x 57.7/100 V, 3 x 230/400
V or 3 x 400/690 V.
