4. Electrical connection
•
Wiring must only be carried out with power off!
•
Check all lines and connections before switching on the equipment!
Don’t use tin-plated strands in connection with screw terminals!
Interference and distortion
All connections are protected against the effects of interference. The location should be selected
to ensure that no capacitive or inductive interferences can affect the sensor or the connection
lines! Suitable wiring layout and choice of cable can minimise the effects of in-terference (e.g.
interference caused by SMPS, motors, cyclic controls and contactors).
Necessary measures
•
Only screened cable should be used. Wire cross section is to be at least 0.14mm², max.
0.5mm².
•
Wiring to the screen and ground (0V) must be star-shaped and across an extensive area.
Ensure that the connection of the screen and earth is made to a large surface area with a
sound connection to minimise impedance.
•
The system should be positioned well away from cables with interference; if necessary a
protective screen or metal housing must be provided. The running of wiring parallel to the
mains supply should be avoided.
•
Contactor coils must be linked with spark suppression.
Supply voltage
The voltages depend on the sensor designs; they are to be taken from the delivery docu-
mentation and the identification plate (e.g.
UB=24V DC ±20%).
5. Maintenance
We recommend cleaning the magnetic strip’s surface from time to time with a soft cloth.
