Safety messages
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.
Before connecting a handheld 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.
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.
CAUTION
Shipping considerations for wireless products.
The unit was shipped to you without the power module installed. Remove the power module prior to
shipping.
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 About this guide
This guide provides basic guidelines for the Rosemount 702. It does not
provide instructions for detailed configuration, diagnostics, maintenance,
service, troubleshooting, or installations. Refer to the Rosemount 702
Reference Manual for more instruction. This guide and the manual are
available electronically on Emerson.com/Rosemount.

2 Wireless considerations
2.1 Power up sequence
The Wireless Gateway should be installed and functioning properly before
any wireless field devices are powered. Install the Power Module,
SmartPower™ Solutions model number 701PBKKF into the Rosemount 702
Transmitter to power the device. Wireless devices should be powered up in
order of proximity from the Gateway, beginning with the closest device,
then working outward from the Gateway. This results in a simpler and faster
network formation. Enable Active Advertising on the Gateway to ensure new
devices are able to join the network faster. For more information see the
Emerson Wireless 1410S Gateway.
2.2 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 2-1: Antenna Position
2.3 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.

2.4 Field Communicator connections
The power module needs to be installed before the Field Communicator can
interface with the Rosemount 702 Wireless transmitter. For HART® Wireless
Transmitter communication via a Field Communicator, a Rosemount 702
Wireless Device Dashboard (DD) is required. To obtain the latest DD, visit
the Field Communicator System Software and Device Description site at:
Emerson.com/Field-Communicator. This transmitter uses the Black Power
Module; Order model number 701PBKKF.

3 Physical installation
The Rosemount Transmitter can be installed in one of two configurations:
•Direct mount, where the switch is connected directly to the Rosemount
702 Transmitter housing’s conduit entry.
•Remote mount, where the switch is mounted separate from the
Rosemount 702 Transmitter housing, then connected to the Rosemount
702 Transmitter.
Select the installation sequence that corresponds to the mounting
configuration.
3.1 Direct mount installation
Note
Direct mount installation should not be employed when using tubing and
connectors such as Swagelok® fittings.

B. Float switch
Procedure
1. Install the switch according to standard installation practices making
sure to use thread sealant on all connections.
2. Attach the Rosemount 702 Transmitter housing to the switch using
the threaded conduit entry.
3. Attach the switch wiring to the terminals as indicated on the wiring
diagram (see Reference information: wiring switch inputs, output
circuits, and leak sensors).

4. Connect the 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 formation.
5. Close the housing cover and tighten to safety specification. Always
ensure a proper seal so the 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. (0.91 m) from any large
structures or buildings, to allow clear communication to other
devices.

Procedure
1. Install the switch according to standard installation practices making
sure to use thread sealant on all connections.
2. Run wiring (and conduit if necessary) from the switch to the
Rosemount 702 Transmitter.
3. Pull the wiring through the threaded conduit entry of the Rosemount
702 Transmitter.
4. Attach the switch wiring to the terminals as indicated on the wiring
diagram (see Reference information: wiring switch inputs, output
circuits, and leak sensors).
5. Connect the power module.
Note
Wireless devices should be powered up in order of proximity from
