NOTICE
This guide provides basic information for the Rosemount 648 Wireless. It does not provide instructions
for detailed configuration, diagnostics, maintenance, service, troubleshooting, or installations. Refer
to the Rosemount 648 Wireless Reference Manual for more instruction. The manual and this guide are
also available electronically on Emerson.com/Rosemount.
WARNING
Failure to follow these installation guidelines could result in death or serious injury. Explosions could
result in death or serious injury.
NOTICE
Shipping considerations for wireless products: (Lithium battery: Black Power Module, model number
701PBKKF). The unit was shipped to you without the Black Power Module installed. Remove the Black
Power Module prior to shipping the unit. Each Black Power Module contains two “C” size primary
lithium batteries. Primary lithium batteries are regulated in transportation by the U. S. Department of
Transportation, and are also covered by IATA (International Air Transport Association), ICAO
(International Civil Aviation Organization), and ARD (European Ground Transportation of Dangerous
Goods). It is the responsibility of the shipper to ensure compliance with these or any other local
requirements. Consult current regulations and requirements before shipping.

1 Wireless considerations
1.1 Power up sequence
The Rosemount™ 648 Wireless and all other wireless devices should be
installed only after the Wireless Gateway (“Gateway”) has been installed and
is functioning properly. Wireless devices should also be powered up in order
of proximity from the Gateway, beginning with the closest. This will result in
a simpler and faster network installation. Enable active advertising on the
Gateway to ensure new devices join the network faster. For more
information, see the Wireless Gateway Reference Manual.
1.2 Antenna position
The antenna should be positioned vertically, either straight up or straight
down, and it should be approximately 3 ft. (1 m) from any large structure,
building, or conductive surface to allow for clear communication to other
devices.
Figure 1-1: Antenna Position
1.3 Conduit entry
Upon installation, ensure each conduit entry is either sealed with a conduit
plug using approved thread sealant, or has an installed conduit fitting or
cable gland with appropriate threaded sealant. Note the conduit entries on
the Emerson 781 Field Link are threaded ½–14 NPT.

1.4 Field Communicator connections
The Black Power Module needs to be installed in the device for the Field
Communicator to interface with the Rosemount 648 Wireless. For HART
Wireless Transmitter communication via a Field Communicator, a
Rosemount 648 Wireless Device Dashboard (DD) is required. Rosemount
648 Wireless Transmitters equipped with Rosemount X-well Technology
requires DD revision 648 Dev. 4 Rev. 1 or higher to view Rosemount X-well
functionality. To obtain the latest DD, visit the Field Communicator System
Software and Device Description site at: Emerson.com/Field-Communicator
Refer to Figure 1-3 for instructions on connecting the Field Communicator to
the Rosemount 648 Wireless Transmitter.

2 Physical installation
2.1 Rosemount 648 Wireless installation
The Rosemount 648 Wireless can be installed in one of two configurations:
•Direct Mount, where the sensor is connected directly to the Rosemount
648 Wireless housing’s conduit entry.
•Remote Mount, where the sensor is mounted separate from the
Rosemount 648 Wireless housing, then connected to the Rosemount
648 Wireless using conduit.
Select the installation sequence that corresponds to the mounting
configuration.
2.2 Direct mount
The direct mount installation should not be used when installing with a
Swagelok® fitting.
Procedure
1. Install sensor according to standard installation practices using
approved thread sealant on all connections.
2. Attach Rosemount 648 Wireless housing to the sensor using the
threaded conduit entry.
3. Attach sensor wiring to the terminals as indicated on the wiring
diagram.
4. Connect Black Power Module.
Note
Wireless devices should be powered up in order of proximity from
the Wireless Gateway, beginning with the closest device to the
gateway. This will result in a simpler and faster network installation.

5. Close housing cover and tighten to safety specification. Always
ensure a proper seal by installing the electronics housing covers so
metal touches metal, but do not over tighten.
6. Position antenna vertically, either straight up or straight down. The
antenna should be approximately 3 ft. (1 m) from any large
structures or buildings, to allow clear communication to other
devices.

2. Run wiring (and conduit, if necessary) from the sensor to the
Rosemount 648 Wireless.
3. Pull wiring through the threaded conduit entry of the Rosemount
648 Wireless.
4. Attach sensor wiring to the terminals as indicated on the wiring
diagram.
5. Connect Black Power Module.
Note
Wireless devices should be powered up in order of proximity from
the wireless gateway, beginning with the closest device to the
Gateway. This will result in a simpler and faster network installation.

2.4 Rosemount X-well Installation
Rosemount X-well Technology is only available in the Rosemount 648
Wireless and 0085 pipe clamp sensor factory assembled complete point
solution. Rosemount X-well Technology will only work as specified with
factory supplied and assembled pipe clamp sensor.
In general, pipe clamp sensor installation best practices shall be followed
(see Rosemount 0085 Pipe Clamp Sensor Reference Manual) with
Rosemount X-well Technology specific requirements noted below:
Procedure
1. Direct mounting of transmitter on pipe clamp sensor is required for
Rosemount X-well Technology to properly function.
2. Transmitter head shall be placed away from dynamic external
temperature sources such as a boiler.
3. Insulation (½-in. thick minimum) is required over the sensor clamp
assembly and sensor extension up to transmitter head to prevent
heat loss. Apply a minimum of six inches of insulation on each side of
the pipe clamp sensor. Care should be taken to minimize air gaps
between insulation and pipe. See Figure 2-5.
Note
DO NOT apply insulation over transmitter head.
4. Although it will come factory configured as such, ensure that pipe
clamp RTD sensor is assembled in 3-wire configuration. See Figure
4-1 for more information.

3 Verify operation
3.1 Four methods of verification
Operation can be verified using four methods at the device via the LCD
display, using the Field Communicator, at the Gateway via the Wireless
Gateway’s integrated web server, or using AMS Wireless Suite or AMS Device
Manager.
LCD display
During normal operation, the LCD display will show the PV value at the
confirmed update rate. Refer to the Rosemount 648 Wireless Reference
Manual for error codes and other LCD display messages. Select the
Diagnostic button to display the TAG, Device ID, Network ID, Network Join
Status, and Device Status screens.
