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.
