Electrical Connection
The read head is connected electrically via a fixed cable with open cores on the side of the
housing. The power is supplied via this connection. The configurable inputs and outputs on the
read head are located at this connection.

Shielding Cables
The shielding of connection lines is required to suppress electromagnetic interference. Estab-
lishing a low resistance or low impedance connection with the protective conductor or equipo-
tential bonding circuit is a particularly important factor in ensuring that these interference
currents do not become a source of interference themselves. The shield of the connection
cable of the read head must be connected to the equipotential bonding on the control cabinet
side.
The following points relating to shielding must be noted:
•
Use metal cable clips that cover large areas of the shielding.
•
Place the cable shield onto the equipotential bonding rail immediately on entering the
switch cabinet.
•
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.

Caution!
Damage to the device
Connecting an alternating current or excessive supply voltage can damage the device or cause
the device to malfunction.
Electrical connections with reversed polarity can damage the device or cause the device to
malfunction.
Connect the device to direct current (DC). Ensure that the supply voltage rating is within the
specified device range. Ensure that the connecting wires on the female cordset are connected
correctly.
