1.1 Installation checklist
□
Make sure that the hazardous area specified on the approval tag is suitable for the
environment in which the meter will be installed.
□
Verify that the local ambient and process temperatures are within the limits of the
meter.
□
If your meter will be wired to a remote-mount 2700 FOUNDATION fieldbus
™
transmitter:
- Refer to the instructions in this manual for preparing the 4-wire cable and wiring
to the processor connections.
- Refer to the instructions in the transmitter installation manual for mounting and
wiring the 2700 FOUNDATION fieldbus
™
transmitter. See Micro Motion
Model 1700 and Model 2700 Transmitters: Installation Manual.
- Consider the maximum cable length between the meter and transmitter. The
maximum recommended distance between the two devices is 1000 ft (300 m).
Micro Motion recommends using Micro Motion cable.
□
For optimal performance, install the meter in the preferred orientation.
The meter will work in any orientation as long as the vibrating tubes remain full of
the process fluid. However, you should validate the meter performance prior to
operation if you have installed it in a non-preferred orientation.

Install the meter so that the flow direction arrow on the meter case matches the
actual forward flow of the process. (Flow direction is also software-selectable.)
