Installationandwiring
• The power supply must be filtered and regulated.
→
Make sure the installation is earthed equipotentially
(power supply - 8081).
→
Connect the different earth connections of the installation to
one another in order to remove any differences in potential
which may arise between the two earth connections.
→
Connect the cable shielding to the earth. Connect the nega-
tive terminal of the power supply to the earth to remove the
effects of the common mode currents. If this connection can-
not be made directly, a 100 nF/50 V capacitor can be fitted
between the negative terminal of the power supply and the
earth.

12-36VDC
(**)
(*) If a direct earthing
connection is not pos-
sible, fit a 100 nF/50 V
capacitor between the
negative terminal of the
power supply and the
earth.
(**) If your cable is
shielded.

danger
risk of injury due to electrical discharge
• Before starting work, make sure that you switch off the supply
voltage and secure it to prevent restarting.
• Do not install the cable near high voltage or high frequency ca-
bles.
• If this is unavoidable, keep to a minimum clearance of 30 cm.
• Observe all applicable accident protection and safety guidelines
