Ground connections of other plant parts that can also carry large currents.
Figure 4-20 Faulty wiring using the digital on-board I/O X11 as an example: Common cable
If a break occurs in the common cable, the current of the outputs flows via terminal 30 to the
module and via terminal 40 to the central terminal block. The current flows via the module.
WARNING
Current flow with faulty wiring
If a break occurs in the common cable, the current can be very high, depending on the
plant, and lead to the destruction of the module.
