NOTICE
This guide provides basic guidelines for the Emerson Wireless Field Link. It does not provide
instructions for diagnostics, maintenance, service, or troubleshooting. This guide is also available
electronically on www.Emerson.com.
WARNING
Failure to follow these installation guidelines could result in death or serious injury.
Ensure only qualified personnel perform the installation.
Explosions could result in death or serious injury.
Installation of the transmitters in a hazardous environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Please review the
Product Certifications section for any restrictions associated with a safe installation.
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause
electrical shock.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following
conditions:
This device may not cause harmful interference.
This device must accept any interference received, including interference that may cause undesired
operation.
This device must be installed to ensure a minimum antenna separation distance of 8-in. (20 cm) from
all persons.

1 Wireless considerations
1.1 Power up sequence
The Emerson Wireless Field Link and wireless I/O should be installed and
functioning properly before the power modules are installed in any wireless
field devices. Wireless field devices should also be powered up in order of
proximity from the Field Link beginning with the closest. This will result in a
simpler and faster network installation.
1.2 Mounting location
The Field Link should be mounted in a location that allows convenient access
to the host system network (wireless I/O) as well as the wireless field device
network.
Find a location where the Field Link has optimal wireless performance.
Ideally this will be 15 to 25 ft. (4,6 to 7,6 m) above the ground or 6 ft. (2 m)
above obstructions or major infrastructure.

1.3 Antenna position
The antenna should be positioned vertically, either straight up or straight
down, and should be approximately 3 ft. (1 m) from any large structure,

building, or conductive surface to allow for clear communication to other
devices.

1.4 Conduit plug
The temporary orange plugs should be replaced with the included conduit
plugs using approved thread sealant.

1.5 Intended use
The Field Link must be used in conjunction with a network manager or
network Gateway. The Field Link then functions as a translator between the
wired network and a wireless field network.

2 Physical installation
2.1 Pipe mounting
Procedure
1. Insert larger U-bolt around 2-in. pipe/mast, through the saddle,
through the L-shaped bracket, and through the washer plate.
2. Use a 1/2-in. socket-head wrench to fasten the nuts to the U-bolt.
3. Insert smaller U-bolt around base the Field Link and through the Lshaped bracket.
4. Use a 1/2-in. socket-head wrench to fasten the nuts to the U-bolt.
Figure 2-1: Mounting
2.2 Power and data wiring
Procedure
1. Remove housing cover labeled “Field Terminals.”
2. Connect the positive power lead to the “+” power terminal and the
negative power lead to the “–” terminal.
3. Connect the Data + lead to the “A (+)” terminal and the Data – lead
to the “B (–)” terminal.
4. Plug and seal any unused conduit connections.
5. Replace the housing cover.

2.3 Grounding
The Field Link enclosure should always be grounded in accordance with
national and local electrical codes. The most effective grounding method is a
direct connection to earth ground with minimal impedance. Ground the
Field Link by connecting the external ground lug to earth ground. The
connection should be 1 Ω or less.

3 Verify operation
3.1 Power-up sequence
Upon applying power to the Field link the LCD display meter will activate and
display a series of startup screen. The following screens are displayed during
startup.
1. Startup Screen 1 – All segments on
2. Startup Screen 2 – Device identification
3. Startup Screen 3 – Tag
4. Startup Screen 4 – Status
3.2 Normal operation
After the initial startup screens the Field Link will cycle through several
periodic screens.
1. Electronics Temperature Screen
2. Percent Range Screen
3. Wired Interface Usage
4. Radio Interface Usage
The Field Link will continue to rotate through each periodic screen through
the course of normal operation. If any diagnostic or fault condition occurs, a
corresponding diagnostics screen will appear.
