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
available electronically on EmersonProcess.com/Rosemount.

Failure to follow these installation guidelines could result in death or serious injury.

 Make sure only qualified personnel perform the installation.

Explosions could result in death or serious injury.

 Before connecting a Field Communicator in an explosive atmosphere, make sure the instruments are

installed in accordance with intrinsically safe or non-incendive field wiring practices.

 Verify the operating atmosphere of the transmitter is consistent with the appropriate hazardous

locations certifications.

Process leaks could result in death or serious injury.

 Do not remove the thermowell while in operation.

 Install and tighten thermowells and sensors before applying pressure.

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 devi ce must accept any interferen ce received, including interference that may cause undesired

operations.

 This device must be installed to ensure a minimum antenna separation distance of 20 cm from all

person.

 The black power module may be replaced in a hazardous area. The black power module has surface

resistivity greater than one giga-ohm and must be properly installed in the wireless device enclosure.
Care must be taken during transportation to and from the point of installation to prevent electrostatic
charge build-up.

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. Depar tment 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.

1.0 Wireless considerations

1.1 Power up sequence

The Rosemount 648 Wireless and all other wireless devices should be installed
only after the Smart 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
Smart 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.

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.

A. Conduit entry

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 475 Field Communicator System Software and Device
Description site at:

EmersonProcess.com/Field-Communicator

Refer to Figure 3 on page 5 for instructions on connecting the Field
Communicator to the Rosemount 648 Wireless Transmitter.

2.0 Physical 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.

2.1 Direct mount

The direct mount installation should not be used when installing with a
Swagelok® fitting.

1. Install sensor according to standard installation practices using approved

2. Attach Rosemount 648 Wireless housing to the sensor using the threaded

3. Attach sensor wiring to the terminals as indicated on the wiring diagram.

conduit entry.

Note

Wireless devices should be powered up in order of proximity from the Smart Wireless
Gateway, beginning with the closest device to the gateway. This will result in a simpler and
faster network installation.

Antenna rotation allows for best
installation practices in any
configuration.

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.

2.2 Remote mount

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 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.

2.3 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.

7

Quick Start Guide

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:

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 (

1

/2-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 8 on page 8.

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 11 for more
information.
