Components Function Diagram
Potential bridges for
front connector
You jumper two terminals with potential bridges.
The potential bridges are included in the scope of delivery of the front
connector and can be ordered as Accessories/spare parts (Page 335).
The front connectors for 25 mm modules have no potential bridges.
Therefore, you should also observe the information in the product
manual for the respective digital or analog module.
Shielding bracket The shield bracket is an insertable bracket for modules with EMC-
critical signals (e.g. analog modules, technology modules), and (to-
gether with the shield clamp) permits the low impedance application of
shielding with minimal installation times.
The shield bracket is included in the scope of delivery of the analog
modules, technology modules and compact CPUs (for onboard I/O)
and can be ordered as Accessories/spare parts (Page 335).
Shield clamp The shield clamps are used to attach cable shielding to the shielding
bracket.
The shield clamp is included in the scope of delivery of the analog
modules, technology modules and compact CPUs (for onboard I/O)
and can be ordered as Accessories/spare parts (Page 335).
Power supply element The power supply element is inserted in the front cable connector, and
serves to supply power to modules with EMC-critical signals (analog
modules, technology modules).
The power supply element (connection technology: screw terminal) is
included in the scope of delivery of the analog and technology mod-
ules and can be ordered as Accessories/spare parts (Page 335).
Labeling strips for the
exterior of the front
cover of the I/O mod-
ules
The labeling strips are used to label the modules for specific plants.
You can label the labeling strips using a machine. The labeling strips
are available in various colors:
• Al gray: Non-fail-safe modules
•
Yellow: Fail-safe modules
The labeling strips are included in the scope of delivery of the I/O
modules and compact CPUs (for onboard I/O). Additional labeling
strips can be ordered as Accessories/spare parts (Page 335).
4-pole connection plug
for supply voltage of
the CPU/interface
module
The supply voltage is supplied by means of the 4-pole connection
plug.
