3.1.5.2 Power Jumper Contacts
The field power supply is distributed in the I/O system via the power jumper contacts. The
contacts on the left side are male contacts; those on the right side are touch-proof spring
contacts.
3.1.5.3 DIN-Rail Contact
Many components of the I/O system transmit electromagnetic interference to the DIN-rail
via DIN-rail contacts. The DIN-rail contacts of the modules are automatically connected
when they are snapped on to the DIN-rail.
For the I/O modules, there is usually no direct connection between the DIN-rail contact
and the ground connections of the wiring interface and the associated power jumper con-
tacts. The specific design is described in
