Connecting the Sensor
Connecting the Supply Voltage
To supply voltage to the sensor, proceed as follows:
1.
Connect the 8-pin M12 socket on the power cable to the plug located on the side of the
housing.
2.
Screw the union nut onto the connector until it reaches the end stop.
This ensures that the power cable cannot be pulled out inadvertently.
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.
Note
Shielding Cables
The shielding of connection lines is required to suppress electromagnetic interference.
Establishing a low-resistance or low-impedance connection with the protective conductor or
equipotential bonding circuit is an especially important factor in ensuring that these
interference currents do not become a source of interference themselves. Only use connection
lines with braid. Avoid connection lines with film shield because this would increase the line
capacities. The shielding is integrated at both ends, i.e., in the switch cabinet
and
at the
sensor. 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 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 conductor cross section used for grounding should be as large as possible.
