The power module with the wireless unit contains two “C” size primary lithium/thionyl chloride
batteries. Each battery contains approximately 2.5 grams of lithium, for a total of 5 grams in
each pack. Under normal conditions, the battery materials are self-contained and are not
reactive as long as the batteries and the pack integrity are maintained. Care should be taken to
prevent thermal, electrical, or mechanical damage. Contacts should be protected to prevent
premature discharge.
Battery hazards remain when cells are discharged.
Power modules should be stored in a clean and dry area. For maximum battery life, storage
temperature should not exceed 30 °C.
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.
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 approvals section of the 702 Reference Manual for any restrictions associated
with a safe installation.
Before connecting a Field Communicator in an explosive atmosphere, ensure the
instruments are installed in accordance with intrinsically safe or non-incendive field
wiring practices
Process leaks may cause harm or result in death:
Install and tighten process connectors before applying pressure
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 702 transmitter and all other wireless devices should be installed only after the Smart
Wireless Gateway has been installed and is functioning properly. Wireless devices should
also be powered up in order of proximity from the Smart Wireless Gateway, beginning with
the closest. This will result in a simpler and faster network installation.
Shipping considerations for wireless products:
The unit was shipped to you without the power module installed. Please remove the power
module prior to shipping.
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.

Introduction
1.4.1 Functions of the transmitter
Switches produce either an open or closed signal. By using simple HART configuration, the 702
transmitter converts the switch signal to a wireless-enabled signal.
1.4.2 Wireless Considerations
Power Up Sequence
The Smart Wireless Gateway should be installed and functioning properly before any wireless
field devices are powered. Install the Black Power Module, SmartPower™Solutions model
number 701PBKKF (part number 00753-9220-0001) into the 702 transmitter to power the
device. 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 (Document Number 00809-0200-4420).
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
Preparing (or sealing) the conduit entries
Upon installation, ensure that each conduit entry is either sealed with a conduit plug with
appropriate thread sealant, or has an installed conduit fitting or cable gland with appropriate
thread sealant.

1.4.3 Choosing an Installation Location and Position
Choosing an Installation Location and Position
When choosing an installation location and position, take into account access to the
transmitter. For best performance, the antenna should be vertical with space between objects in
a parallel metal plane, such as a pipe or metal framework, as the pipes or framework may
adversely affect the antenna’s performance.

1.4.4 Electrical
Caring for the Power Module
The Rosemount 702 Wireless Discrete Transmitter is self-powered. The included Black Power
Module contains two “C” size primary lithium/thionyl chloride batteries. Each battery contains
approximately 2.5 grams of lithium, for a total of 5 grams in each pack. Under normal
conditions, the battery materials are self-contained and are not reactive as long as the batteries
and the power module are maintained. Care should be taken to prevent thermal, electrical, or
mechanical damage. Contacts should be protected to prevent premature discharge.
Use caution when handling the power module, it may be damaged if dropped from heights in
excess of 20 feet (6.10 m).
Making Switch Connections
Make switch connections through the cable entry in the side of the connection head. Be sure to
provide adequate clearance for cover removal.
1.4.5 Verifying Operating Atmosphere
Verify that the operating atmosphere of the transmitter is consistent with the appropriate
hazardous locations certifications.
Isolating the transmitter from sources of heat
The transmitter will operate within specifications for ambient temperatures between -40 and
185 °F (-40 and 85 °C). Heat from the process is transferred from the switch to the transmitter
housing. If the expected process temperature is near or beyond specification limits, consider
using an extension, or remote mount the transmitter to thermally isolate it from the process.
Figure 1-4 provides an example of the relationship between the transmitter housing
temperature rise and the extension length.

Introduction
Example
The transmitter specification limit is 185 °F (85 °C). If the ambient temperature is 131 °F (55 °C)
and the maximum process temperature to be measured is 1500 °F(815 °C), the maximum
permissible connection head temperature rise is the transmitter specification limit minus the
ambient temperature (moves 185 °F to 131 °F [85 to 55 °C]), or 86 °F (30 °C).
In this case, an extension of 5-in. (0.13 m) meets t his requirement, but 6-in. (0.15 m) provides
an additional margin of protection, thereby reducing risk of ambient thermal damage.
