General Structure of a Potential Group

When using the interference-free I/O module 750-1515/040-000 in safety-related
applications, the I/O modules belonging to a safety switching device shall be
combined to form a potential group. The power supply of the potential group may
only be provided via the following supply or filter modules:

Table 22: Supply or Filter Modules for Setting up a Potential Group

Supply Terminal Blocks
Field-side power supply filter
Power supply filter
The potential group must be terminated by one of the listed supply or filter
modules or by the end module 750-600/040-000.
