danger
risk of injury due to electrical discharge
• Shut down and isolate the electrical power source before carry-
ing out work on the system.
• Observe all applicable accident protection and safety regula-
tions for electrical equipment.
note
• Use cables with an operating temperature limit suitable for your
application.
• Protect the power supply of a version with 2 pulse outputs by
means of an 800 mA fuse and a switch.
• Protect the power supply of a version with 1 pulse output by
means of a 50 mA fuse and a switch.
use a high quality electrical power supply (filtered and
regulated).
• Under normal conditions of use, cable with a cross section
of 0.75 mm should be enough to transmit the signal.
2
• Do not install the cable near high voltage or high frequency
cables.
• If this is unavoidable, keep a minimum distance of 30 cm.
Type 8011
make sure the installation is equipotential (power supply
- 8011):
• Connect the different earth connections of the installation to
one another in order to remove any differences in potential
which may arise between two earth connections.
• Correctly connect the cable shielding to the earth.
• Connect the negative power supply terminal to the earth to
eradicate the effects of common mode currents. If this con-
nection cannot be made directly, a 100 nF/50 V capacitor
can be fitted between the negative power supply terminal
and the earth.
