6.3 Installation
6.3.1 Measurement Currents
It is recommended metering current transformer (CT) outputs to be connected as follows :
•
L1- phase current to terminals 41 ( k ) and 42 ( l )
•
L2- phase current to terminals 43 ( k ) and 44 ( l )
•
L3- phase current to terminals 1 ( k ) and 2 ( l )
A metering current transformer of nominal output current 5 or 1 A can be used.
