Installation and commissioning
Make the external connections on the screw terminals according to the
terminal diagram.
All connectors have an identification number, for example X11. You can
mark the female connectors the same way. The individual terminals are
numbered from top to bottom: 1, 2, 3,... (see a signal connector in Fig. 6).
At installation, all wiring on the female part of the connector can be per-
formed before plugging it into the male part, on the relay.
Identify the cables from the current and voltage transformers regarding
phases and connect the cables to the proper terminal, according to the ter-
minal diagram.
