Installation or Replacement of a SIPROTEC 4 Communication Module
The following description assumes the normal case that a SIPROTEC 4 communication module which has not
yet been existing is retrofitted.
If a SIPROTEC 4 communication module has to be removed or replaced, the steps are to be performed in
reverse order.
Note
The installation can only be performed alone or after the installation of the Ethernet module.
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-pole plug connector on the module and the basic I/O board are aligned on top of each
other. The alignment is to be checked via the opening at the bottom of the rack. Fixate the mounting bracket of
the module from the back of the basic-I/O with 2 M 2.5 screws.
