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.

Physical access

Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end
users’ equipment. This could be intentional or unintentional and needs to be protected against.

Physical security is an important part of any security program and fundamental to protecting your
system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for
all systems used within the facility.

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 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 Transmitter installation

The transmitter 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 transmitter
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 transmitter 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.

Procedure

1. Install sensor according to standard installation practices using an
approved thread sealant on all connections.

2. Run wiring (and conduit, if necessary) from the sensor to the
transmitter.

3. Pull wiring through the threaded conduit entry of the transmitter.

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.
