(AWG 19), for shielding (1S, 2S)
- Wire end sleeves 0.5 mm
2
(AWG 20), for all other wires
• The shields may not touch (signal short circuit).

Connect the cable end on the flowmeter sensor side as shown in Fig. 29.
Cable with part number D173D027U01
• Twist the wire mesh shield of the cable and connect to the ground terminal.
• Connect the ground wire of the cable to the SE clamp of the terminal strip.
• Connect all other wires as shown in Fig. 29.
Cable with part number D173D031U01
• Connect the cable ground wire together with the foil shield continuity wire from D1, D2 to the
SE clamp of the terminal strip.
• When using the flowmeter sensor in systems with cathodic corrosion protection (CCP),
connect the cable ground wire together with the foil shield continuity wire from D1, D2 to the
PE clamp of the terminal strip.
• Connect all other wires as shown in Fig. 29.
5.5.3 Connection via cable conduit
Notice - Condensate formation in terminal box
If the flowmeter sensor is permanently connected to cable conduits, there is a possibility that
moisture may get into the terminal box as a result of condensate formation in the cable
conduit.
Ensure that the cable entry points on the terminal box are sealed.
