Shielding Cables
The shielding of connection lines is required to suppress electromagnetic interference.
Establishing a low resistance or low impedance connection with the conductor or equipotential
bonding circuit is a particularly important factor in ensuring that these interference currents do
not become a source of interference themselves. Always use connection lines with braided
shield; never use connection lines with a film shield. The shield is integrated at both ends, i.e.,
in the switch cabinet or on the controller
and
on the read head. The grounding terminal
available as an accessory allows easy integration in the equipotential bonding circuit.
In exceptional cases, the shielding of a connection at one end may be more favorable if
An equipotential bonding cable is not laid or cannot be laid.
A film shield is used.
The following points relating to shielding must also be noted:
Use metal cable clips that cover large areas of the shield.
After installing the cable shield in the control cabinet, place it directly on the equipotential
bonding rail.
Direct the protective grounding connections to a common point in a star configuration.
The cross-section of the cables used for grounding should be as large as possible.

Note!
"Service" Plug Connector
The plug connector marked with
"Service"
is used only to set the parameters of the reader.
Communication with the PC on which the configuration software is running and the power
supply itself are both fed through the parameterization cable (cable unit for service interface
with the power supply). A description of the connection can be found in the "Vision
Configurator" configuration software manual.
