See technical manual for details about different type of
communication modules.
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.
See the installation manual for more information about the case and
the plug-in unit.
The connection diagrams of different hardware modules are presented in this manual.
