The SIPROTEC 4 communication module is inserted via the large window in the plastic supporting plate. The
direction of insertion is not arbitrary. The module is held at its mounting bracket. The opposite end of the module
is inserted with the same orientation in the window opening, under the supporting plate and any existing exten-
sion I/O. The module bracket is turned towards the Ethernet module locking latch at the supporting plate. Thus,
even the longest connection elements of the communication module can be moved in this space between the
lower supporting plate reinforcement and the locking latch in the direction of the transformer module. The
mounting bracket of the module is now drawn up to the stop in the direction of the lower supporting plate rein-
forcement. Thus, the 60-pin plug connector on the module and the basic I/O board are aligned on top of each
other. The alignment has to be checked via the opening at the bottom of the rack. Attach the module's mounting
rail from the back side of the basic I/O using 2 M 2.5 screws.
