4.4.5 Preparing signal cable A, connection to measuring sensor
INFORMATION!
Assembly materials and tools are not part of the delivery. Use the assembly materials and tools
in compliance with the applicable occupational health and safety directives.
• The outer shield (60) is connected in the terminal compartment of the measuring sensor
directly via the shield and a clip.
• Bending radius: ≥ 50 mm / 2"
Required materials
• PVC insulating tube, Ø2.0...2.5 mm / 0.08...0.1"
• Heat-shrinkable tubing
• Wire end ferrule to DIN 46 228: E 1.5-8 for the stranded drain wire (1)
• 2 wire end ferrules to DIN 46 228: E 0.5-8 for the insulated conductors (2, 3)
Figure 4-5: Preparing signal cable A, connection to measuring sensor
a = 50 mm / 2"
b = 10 mm / 0.39"
1 Strip the conductor to dimension a.
2 Trim the outer shield (60) to dimension b and pull it over the outer sheath.
3 Remove the stranded drain wire (6) of the outer shield and the inner shield. Make sure not to
damage the stranded drain wire (1) of the inner shield.
4 Slide an insulating tube over the stranded drain wire (1).
5 Crimp the wire end ferrules onto conductors 2 and 3 and the stranded drain wire (1).
6 Pull the heat-shrinkable tubing over the prepared signal cable.
