If possible, install the transmitter in a location that will prevent direct exposure to sunlight.
The environmental limits for the transmitter may be further restricted by hazardous area
approvals.
1.6 Hazardous area classifications
If you plan to mount the transmitter in a hazardous area:
•Verify that the transmitter has the appropriate hazardous area approval. Each
transmitter has a hazardous area approval tag attached to the transmitter housing.
•Ensure that any cable used between the transmitter and the sensor meets the
hazardous area requirements.
1.7 Power requirements
Self-switching AC/DC input, automatically recognizes supply voltage
•85 to 265 VAC, 50/60 Hz, 6 watts typical, 11 watts maximum
•18 to 100 VDC, 6 watts typical, 11 watts maximum

amendment 2, and Installation (Overvoltage) Category II, Pollution Degree 2
Note
For DC power:
•Power requirements assume a single transmitter per cable.
•At startup, the power source must provide a minimum of 1.5 amps of short-term current per
transmitter.
•Length and conductor diameter of the power cable must be sized to provide 18 VDC
minimum at the power terminals, at a load current of 0.5 amps.

1.8 Orientation
You can mount the transmitter in any orientation as long as the conduit openings do not
point upward.
CAUTION!
Upward-facing conduit openings risk condensation moisture entering the transmitter housing,
which could damage the transmitter.

Installation Manual 9

1.9 Accessibility for maintenance
Mount the meter in a location and orientation that satisfies the following conditions:
•Allows sufficient clearance to open the transmitter housing cover. Micro Motion
recommends 8–10 inches (200–250 mm) clearance at the rear of the transmitter.
•Provides clear access for installing cabling to the transmitter.

2 Mounting and sensor wiring for
integral installations
Topics covered in this chapter:
•Mounting and sensor wiring
•Rotate the transmitter on the sensor (optional)
•Rotate the user interface on the transmitter (optional)
•Ground the meter components
2.1 Mounting and sensor wiring
There are no separate mounting requirements for integral transmitters, and no need to
connect wiring between the transmitter and the sensor.
2.2 Rotate the transmitter on the sensor (optional)
In integral installations, you can rotate the transmitter on the sensor up to 360º in 90º
increments.

Procedure
1. Loosen each of the four cap screws (4 mm) that fasten the transmitter to the base.
2. Rotate the transmitter counter-clockwise so that the cap screws are in the unlocked
position.
3. Gently lift the transmitter straight up, disengaging it from the cap screws.
Important
Do not disconnect or damage the wires that connect the transmitter to the core processor.
4. Rotate the transmitter to the desired orientation.
Important
Do not pinch or stress the wires.
The slots on the transition ring should be aligned with the cap screws.
5. Gently lower the transmitter onto the base, inserting the cap screws into the slots.
6. Rotate the transmitter clockwise so that the cap screws are in the locked position.
7. Tighten the cap screws, torquing to 2.3 to 3.4 N-m.

2.3 Rotate the user interface on the transmitter
(optional)
The user interface on the transmitter electronics module can be rotated 90º or 180° from
the original position.

Notes
•When using the touch buttons, you must cover at least an 8 mm diameter circle over the
surface above the touch button: using your thumb may be more effective because it has a
greater surface area.
•When the housing cover is removed, the touch buttons do not function.
Procedure
1. Shut off power to the unit.
2. Remove the end-cap clamp by removing the cap screw.
3. Turn the display cover counterclockwise to remove it from the main enclosure.
4. Carefully loosen (and remove if necessary) the semicaptive display screws while
holding the display module in place.
5. Carefully pull the display module out of the main enclosure until the sub-bezel pin
terminals are disengaged from the display module.

Installation Manual 13

Note
If the display pins come out of the board stack with the display module, remove the pins and
reinstall them.
6. Rotate the display module to the desired position.
7. Insert the sub-bezel pin terminals into the display module pin holes to secure the
display in its new position.
8. If you have removed the display screws, line them up with the matching holes on the
sub-bezel, then reinsert and tighten them.
9. Place the display cover onto the main enclosure.
10. Turn the display cover clockwise until it is snug.
11. Replace the end-cap clamp by reinserting and tightening the cap screw.
12. Restore power to the transmitter.
2.4 Ground the meter components
In an integral installation, all components are grounded together.
Prerequisites
If national standards are not in effect, adhere to the following guidelines for grounding:
•Use copper wire, 14 AWG (2.5 mm2) or larger wire size.
•Keep all ground leads as short as possible, less than 1 Ω impedance.
•Connect ground leads directly to earth, or follow plant standards.
Procedure
Ground via the piping, if possible (see sensor documentation). If grounding via the piping
is not possible, ground according to applicable local standards using the transmitter’s
internal or external ground screw.

wire remote installations
Topics covered in this chapter:
•Mounting options
•Prepare the 4-wire cable
•Wire the transmitter to the sensor
•Rotate the user interface on the transmitter (optional)
•Ground the meter components
3.1 Mounting options
There are two options available for mounting the transmitter:
•Mount the transmitter to a wall or flat surface.
•Mount the transmitter to an instrument pole.
3.1.1 Mount the transmitter to a wall
Prerequisites
•Micro Motion recommends the use of 5/16-18 (8 mm–1.25) fasteners that can
withstand the process environment. Micro Motion does not supply bolts or nuts as
part of the standard offering (general purpose bolts and nuts are available as an
option).
•Ensure that the surface is flat and rigid, does not vibrate, or move excessively.
•Confirm that you have the necessary tools, and the mounting kit shipped with the
transmitter.
Procedure
1. If desired, re-orient the transmitter on the mounting bracket.
a. Remove the junction end-cap from the junction housing.
b. Loosen each of the four cap screws (4 mm).
c. Rotate the bracket so that the transmitter is oriented as desired.
d. Tighten the cap screws, torquing to 30 to 38 in-lbs (3 to 4 N-m).
e. Replace the junction end-cap.
