See the technical manual for details about different types
of communication modules.
1) The 0.2/1 A input is normally used in applications requiring sensitive earth-fault protection and featuring
core-balance current transformers.
Rated values of the current and voltage inputs are basic setting parameters of the
protection relay. The binary input thresholds are selectable within the range 16…176
V DC by adjusting the binary input setting parameters.
The connection diagrams of different hardware modules are presented in this manual.
See the installation manual for more information about the case and
the plug-in unit.
