If the terminal box is to be potted subsequently on-site, a special
two-component potting compound can be ordered separately.
Potting is only possible if the sensor is installed horizontally.
Observe the following instructions during work activity:
• Complete the installation before potting in order to avoid
moisture penetration. Before starting, check all the
connections for correct fitting and stability
•
Do not overfill the terminal box. Keep the potting
compound away from the O-ring and the gasket / groove
(see Figure 32).
• Prevent the two-component potting compound from
penetrating the cable conduit (Conduit) for an ½ in NPT
installation (if used).
Connecting the transmitter
Connecting the power supply
The line voltage and power consumption are indicated on the
name plate for the transmitter. The wire cross-section for the
power supply must meet the requirements for the main fuse
(VDE 0100). The power consumption is ≤
45 VA (sensor including
transmitter).
The power supply is connected to terminal L (phase), N (neutral),
or 1+, 2-, and , in accordance with the information on the name
plate.
The power supply cable must be rated for the current
consumption of the flowmeter system. The leads must comply
with IEC 227 and/or IEC 245.
Connect a switch or a line switch in the power supply line to the
transmitter. This switch should be located near the transmitter
and marked as being associated with the device. The transmitter
and the sensor should be connected to functional ground in
accordance with international standards.
Note
Please observe the limit values of the power supply (see
‘Specification’). Please note that there is a voltage drop of the
24 V AC/DC power supply line if the cables are extremely long or
if the conductor cross section is extremely small.
The pin configuration must be made in accordance with the
electrical connections in
