Caution!
!
The printed circuit boards of digital equipment contain CMOS circuits. These shall not
be withdrawn or inserted under live conditions! The modules must be so handled that
any possibility of damage due to static electrical charges is excluded. During any
necessary handling of individual modules or printed circuit boards the recommenda-
tions relating to the handling of electro-statically endangered components (EEC) must
be observed. In installed conditions, the modules are in no danger.

Connection Notes

A detailed description of the connection technology is given in the SIPROTEC

The terminal screws are slot screws and can be turned with a normal screwdriver 6 × 1 mm.
The following connectors may exist (Figure 11):
Connection modules for voltages, 18-pole,
connection modules for voltages, 12-pole,
connection modules for current, 8-pole.
Figure 11 shows the designation scheme of the connection modules, Figure 12 shows the
accessories. The terminal links are used for grouping of electrical connection points, the
covering caps are necessary in order to achieve protection against electric shock, after
having made the connection.
