IMPORTANT NOTICE
This installation guide provides basic guidelines for the Rosemount 848T. It does not
provide instructions for detailed configuration, diagnostics, maintenance, service,
troubleshooting, or installations. Refer to the Rosemount 848T reference manual
(Document Number 00809-0100-4848) for more instruction. The manual and this QIG are
also available electronically on www.rosemount.com.
WARNING
Explosions could result in death or serious injury:
Installation of this transmitter in an explosive 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.
• Before connecting a Rosemount 375 Field Communicator in an explosive
atmosphere, ensure the instruments are installed in accordance with intrinsically safe
or non-incendive field wiring practices. Electrical shock can result in 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 20 cm from all persons.
• The power module may be replaced in a hazardous area. The power module has
surface resistivity greater than one gigaohm 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.
IMPORTANT NOTICE
Shipping considerations for wireless products:
The unit was shipped to you without the power module installed. Please remove the
power module prior to shipping the unit.
Each 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. Please consult current regulations and requirements before shipping.

WIRELESS CONSIDERATIONS
Power Up Sequence
The Power Module should not be installed on any wireless device until the Smart Wireless
Gateway (“Gateway”) is installed and 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 that new devices join the network faster. For more information see the Smart
Wireless Gateway Manual (Doc. No. 00809-0200-4420).
Antenna Position
The antenna should be positioned vertically 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.
Conduit Plug
The temporary orange plugs should be replaced with the included conduit plugs using
approved thread sealant.

STEP 1: PHYSICAL INSTALLATION
Initial Configuration
If the device was ordered with a factory configured Network ID and Join Key, it should join
the network with no user input. If unsure, the Network ID and the Join Key may be manually
entered to match the Gateway’s.
The Network ID and Join Key may be obtained from the Gateway on the
Setup>Network>Settings page on the web server (see Figure below).
The Network ID and Join Key may be changed in the wireless device by using the following
Fast Key sequence.
Sensor Configuration
Sensor inputs can be configured for different sensor types. To verify or change the sensor
configuration with a 375 handheld communicator, use the following Fast Key sequence.
Remote Mount
The Rosemount 848T Wireless can only be installed in the Remote Mount configuration
where the sensor is mounted separate from the 848T housing, then connected to the 848T
via conduit.
1. Install the sensor according to standard installation practices. Be sure to use thread
sealant on all connections.

STEP 1 CONTINUED...
2. To reduce sensor wiring length, mount the Rosemount 848T Wireless transmitter central
to all of the measurements. When installing the 848T wireless, the conduit entries need
to be facing downward. If using the mounting bracket (Option Code B6), mount to a 2-in.
pipe.
3. Run wiring (and conduit, if necessary) from the sensor to the 848T. For an easier
installation, use the outside conduit entries as shown below. Any unused conduit entries
should be sealed with approved sealant using the included threaded conduit plugs.
4. Pull the wiring through the threaded conduit entry of the 848T.
5. Attach the sensor wiring to the terminals as indicated on the wiring diagram. Note that
Terminal screw 5 is for attaching the shield wire of the sensor to the device. See 848T
Wireless Reference Manual (Document No. 00809-0100-4848) for more information.

6. To connect the power module, remove the plastic plug from the receptacle.
7. After initial installation, close the housing cover securely. Always ensure a proper seal by
installing the electronics housing cover so that metal touches metal, but do not over
tighten.
8. Position the antenna vertically. The antenna should be approximately three feet (1 m)
from any large structures or buildings to allow clear communication to other devices.
STEP 2: VERIFY OPERATION
Operation can be verified using one of three methods: 375 Field Communicator, the Smart
Wireless Gateway’s integrated web interface, or via AMS™Wireless Configurator.
375 Field Communicator
For HART communication, a 848T Wireless DD is required. For connecting with a 375 Field
Communicator, refer to Figure 3: Connection Diagram on page 4.
Smart Wireless Gateway
In the Gateway’s integrated web interface, navigate to the Explorer page. This page shows
whether the device has joined the network and if it is communicating properly.
NOTE:
It may take several minutes for the device to join the network.
NOTE:
If the device joins the network and immediately has an alarm present, it is likely due
to sensor configuration. Check the sensor wiring (see Rosemount 848T Terminal
Diagram on page 9) and the sensor configuration (see 848T Fast Key Sequence for
handheld communicator on page 9).
