The terminals 230 V, 115 V, N and PE are provided as fixed terminals.
7.1.1 Earthing
For earthing the WIC connection terminal PE is used.
The measuring winding (terminals S1and S2) of the CTs must not be earthed, oth-
erwise the measurement results are distorted, ensuring in erratic behavior of the
relay. Connection D of the respective test winding can externally be connected with
terminal PE.
