INSTALLATION
In particular, consumption of the relay input circuit must not exceed 0.2 VA while the load (expressed
in VA) constituted by the conductors is given by:
0.018 × L × I
n
2
/ S
where:
L the overall length, expressed in m, of the two conductors in relation to each phase;
I
n
nominal current of the line CT expressed in A;
S cross sectional area of the current conductors expressed in mm
2
.
It is recommended that cabling of a suitable thickness be used in order to limit wear of the CT sec-
ondary circuits.
Earth connection
A protective ground connection is required: the section of the cable shall be not less than 2.5 mm
