Notes
1.
CT circuits are shown connected to
1A tap - use alternative tap for 5A rated
CTs.
2.
CT and earth connections are typical
only.
3.
Application shows use of SEF/REF
as an SEF input. Use of the input for high-
impedance REF requires an additional
setting resistor, and may also require a
metrosil.

CTs.
2.

3.
Application shows use of Holmgreen
connection for E/F circuit. Use of separate
ring-core CT is also possible.
