3.1 Wiring diagram
This section includes instructions for making all the necessary electrical connections to the AT600 flow meter. Refer to
figure 23 below for the complete wiring diagram of the meter.
IMPORTANT: Except for the transducer connector, all electrical connectors are stored in their terminal blocks during
shipment and may be removed from the enclosure for more convenient wiring. Feed the cables through
the cable gland holes on the bottom of the enclosure, attach the wires to the appropriate connectors
and plug the connectors back into their terminal blocks.
After the AT600 is completely wired, proceed to "Initial setup and programming" on page 27 to configure the meter for
operation.
Note:
The HART and Modbus communication options must be selected when ordering the AT600.
Figure 23: Wiring diagram
Attention European Customers! To meet CE Mark requirements, all cables must be installed as
described in “Wiring cable specifications and requirements” on page 144.
