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.
5.3.2

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
SE clamp of the terminal strip.
• Connect all other wires as shown in Fig. 29.

Connecting the transmitter

IMPORTANT (NOTE)
An additional document with Ex safety instructions is available for measuring systems that are
used in explosion hazardous areas. As a result, it is crucial that the specifications and data it
lists are also observed.
5.4.1

Connecting the power supply

The line voltage and power consumption are indicated on the name plate for the transmitter.
A circuit breaker with a maximum rated current of 16 A must be installed in the supply power
line of the transmitter.
The wire cross-sectional area of the supply power cable and the circuit breaker used must
comply with VDE 0100 and must be dimensioned in accordance with the current consumption of
the flowmeter measuring system. The leads must comply with IEC 227 and/or IEC 245.
The circuit breaker should be located near the transmitter and marked as being associated with
the device.
The supply power is connected to terminal L (phase), N (neutral), or 1+, 2-, and PE, as stated
on the name plate.
Connect the transmitter and flowmeter sensor to functional ground.
Important (Note)
• Observe the limit values for the supply power provided in the data sheet and operating
instructions.
• Observe the voltage drop for large cable lengths and small cable cross-sections. The
voltage at the terminals of the device may not fall below the minimum value required.
• Complete the electrical connection according to the connection diagram.
