Two terminals can be bridged with potential bridges.
The potential bridges are included in the scope of delivery of the front
connector, and may be ordered as a spare part (Page 212).
The front connectors for 25 mm modules have no potential bridges.
Therefore, you should also observe the information in the manual for
the respective analog module.
The shielding bracket is an insertable bracket for modules with EMC-
critical signals (e.g., analog modules, technology modules), and
(together with the shielding clamp) permits the low impedance
application of shielding with minimal installation times.
The shielding bracket is included in the scope of delivery of the analog
and technology modules, and may be ordered as an accessory
(Page 212).
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 and
technology modules, and may be ordered as an accessory
(Page 212).
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
modules, and may be ordered as an accessory (Page 212).
You can insert labeling strips for the system-specific labeling of
modules. You can label the labeling strips using a machine. The
labeling strips are available in various colors.
The labeling strips are included in the scope of delivery of the I/O
modules. Additional labeling strips may be ordered as Accessories
(Page 212).
