Device Safety Considerations
 Reading these Instructions
Before operating the device, read these instructions carefully and understand their safety
implications. In some situations, improperly using this device may result in damage or injury.
Keep this manual in a convenient location for future reference. Note that these instructions
may not cover all details or variations in equipment or cover every possible situation
regarding installation, operation, or maintenance. Should problems arise that are not
covered sufficiently in the text, immediately contact Customer Support for further
information.
 Protecting Operating Processes
A failure of this device — for whatever reason -- may leave an operating process without
appropriate protection and could result in possible damage to property or injury to persons.
To protect against this, you should review the need for additional backup equipment or
provide alternate means of protection (such as alarm devices, output limiting, fail-safe
valves, relief valves, emergency shutoffs, emergency switches, etc.). Contact Remote
Automation Solutions for additional information.
 Returning Equipment
If you need to return any equipment to Remote Automation Solutions, it is your
responsibility to ensure that the equipment has been cleaned to safe levels, as defined
and/or determined by applicable federal, state and/or local law regulations or codes. You
also agree to indemnify Remote Automation Solutions and hold Remote Automation
Solutions harmless from any liability or damage which Remote Automation Solutions may
incur or suffer due to your failure to ensure device cleanliness.
 Grounding Equipment
Ground metal enclosures and exposed metal parts of electrical instruments in accordance
with OSHA rules and regulations as specified in Design Safety Standards for Electrical Systems,
29 CFR, Part 1910, Subpart S, dated: April 16, 1981 (OSHA rulings are in agreement with the
National Electrical Code). You must also ground mechanical or pneumatic instruments that
include electrically operated devices such as lights, switches, relays, alarms, or chart drives.
 Protecting from Electrostatic Discharge (ESD)
This device contains sensitive electronic components which be damaged by exposure to an
ESD voltage. Depending on the magnitude and duration of the ESD, it can result in erratic
operation or complete failure of the equipment. Ensure that you correctly care for and
handle ESD-sensitive components.
System Training
A well-trained workforce is critical to the success of your operation. Knowing how to correctly install,
configure, program, calibrate, and trouble-shoot your Emerson equipment provides your engineers
and technicians with the skills and confidence to optimize your investment. Remote Automation
Solutions offers a variety of ways for your personnel to acquire essential system expertise. Our full-
time professional instructors can conduct classroom training at several of our corporate offices, at
your site, or even at your regional Emerson office. You can also receive the same quality training via
our live, interactive Emerson Virtual Classroom and save on travel costs. For our complete schedule

Safety First!
Never perform the installation/setup activities described in this document in a hazardous
area. Ensure the area is non-hazardous.
DANGER
EXPLOSION HAZARD: Never remove end cap(s) in a hazardous location. Removing end cap(s)
in a hazardous location could result in an explosion.
DANGER
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
Important
Only use batteries supplied with the flow computer or sold by Emerson as spare parts for this flow
computer. If you substitute a battery you obtain elsewhere you will void your certification unless it
is the identical part from the same manufacturer as that supplied with the flow computer from
Emerson.
DANGER
EXPLOSION HAZARD - Substitution of any components may impair suitability for Class I,
Division 1 or Class I, Division 2.
DANGER

Retaining Clamp and Screw
Removing the Front or Rear End Cap
The flow computer includes two threaded end caps (covers). The front end cap includes a
window for viewing the HMI module, while the rear end cap provides access to the terminal
plate for power and I/O wiring.
DANGER
EXPLOSION HAZARD: Never remove end cap(s) in a hazardous location. Removing end
cap(s) in a hazardous location could result in an explosion.
1. Remove the retaining clamp (if present). Grasp the end cap (front or rear).
Note
If you need more leverage to open or close an end cap than you can get with your
hand, you can place a long screwdriver or other appropriate tool across the two
notches in the end cap to act as a pry bar:

DANGER
EXPLOSION HAZARD: Never remove end cap(s) in a hazardous location. Removing end
cap(s) in a hazardous location could result in an explosion.
1. Grasp the end cap (front or rear).
2. Carefully align the end cap threads with the threads of the enclosure.
Important
When replacing the rear end cap, ensure wires connecting to the terminal plate do not
get crimped or caught between the end cap threads and the enclosure.
3. Screw the end cap clockwise (eight full turns) until it is tightly sealed to the enclosure.
4. Replace the retaining clamp (if applicable).

Bolting Considerations
DANGER
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
If the flow computer installation requires assembly of a process flange, manifold, or flange
adapters, follow these assembly guidelines to ensure a tight seal for optimal performance
characteristics of the flow computer.
Only use bolts supplied with the flow computer or sold by Emerson as spare parts. Refer to
the figures, below, for common flow computer assemblies with the bolt length required for
proper flow computer installation.
Note
For all other manifolds, contact your Emerson Local Business Partner (LBP).
Bolts are typically carbon steel or stainless steel. Confirm the material by viewing the
markings on the head of the bolt and referencing Table 2. If bolt material is not shown in the
table, contact your local Emerson representative for more information.

Use the following bolt installation procedure:
1. Carbon steel bolts do not require lubrication. Stainless steel bolts are factory-coated
with a lubricant to ease installation. Do not apply any additional lubricant when
installing either type of bolt.
2. Finger-tighten the bolts.
3. Torque the bolts to the initial torque value using a crossing pattern. See Table 2 for
initial torque value.
4. Torque the bolts to the final torque value using the same crossing pattern. See Table 2
for final torque value.
5. Verify that the flange bolts protrude through the sensor module before applying
pressure.

Terminal Plate
The terminal plate includes the various terminal blocks (TB) for power and I/O connections.
The terminal plate's appearance varies depending upon whether or not you have the
optional 6-channel expansion I/O board installed with 3.81 mm pitch connectors; when it is
installed there are eight or nine connections per terminal block instead of six 5.08 mm pitch
connections. Compare your device to the pictures to see which terminal plate you have.

Grounding
DANGER
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
The flow computer includes a ground lug on the terminal plate.
1 Ground Lug
• Once you have installed the unit, run a ground wire between the ground lug and a
known good earth ground. You route the ground wire through one of the conduit
fittings.
• Use stranded copper wire to earth ground, and keep the length as short as
possible.
• Clamp or braze the ground wire to the ground bed conductor (typically a stranded
copper AWG 0000 cable installed vertically or horizontally).
• Using a high-wattage soldering iron, tin the wire ends with solder before you insert
them into the chassis ground lug.
• Run the ground wire so that any routing bend in the cable has a minimum radius of
30.48 cm (12 inches) below ground and 20.32 cm (8 inches) above ground.
 For more information on grounding or if your installation uses cathodic protection, refer
to Site Considerations for Equipment Installation, Grounding, and Wiring (D301452X012).
