5 METER DESCRIPTION
5.1 Current inputs
All current inputs are galvanically isolated (internal current transformers).
The meter is adapted to work with external measuring current transformers /
1 A or 5 A /. Displayed current values and derivative values are automatically
converted in relation to the introduced external current transformer ratio.
5.2 Voltage inputs
All voltage inputs are galvanically isolated (internal transformers). Values on
voltage inputs are automatically converted according to the introduced ratio
of the external voltage transformer. Voltage inputs are specified in the order
as 3x57.7/100 V, 3x230/400 V or 3x110/190 V, 3x400/690 V.
