CONNECTION TYPES
As there are shunts at the current measurement inputs of the device, it is mandatory to use a current
transformer except for the connections of current inputs. If, the device will be used on the same current
line by means of analyzers with other shunts, it is recommended that the device is located at the extreme
point.
The device has 5 different connection types. These connection types are described in the following
schemes:
3P4W (Three-Phase Four-Wire) Connection
As it is seen below, four voltage and three current connections including the neutral line are established
in this connection type. Voltage inputs should be connected with 100 mA fuses as shown below.
