5 DESCRIPTION OF THE INSTRUMENT
5.1 Current inputs
All current inputs are galvanically isolated (internal current transformers). The meter is adapted
for use with external current transformers / 1 A or 5 A /. Displayed values of the current and the
derived quantities are automatically calculated by the value of the introduced external
transformer ratio.
5.2 Voltage inputs
All voltage inputs are galvanically isolated (internal voltage transformers). Quantities at voltage
inputs are automatically calculated by the amount of introduced ratio of the external voltage
transformer. Voltage inputs are defined in the order as 3x57.7/100 V, 3x230/400V or
3x110/190V; 3x400/690 V.
5.3 External connections diagram
