Rosemount 708
The power module with the wireless unit contains one "D” size primary lithium/thionyl chloride
batteries. Each battery contains approximately X.X grams of lithium. 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 708 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
NOTICE
The Rosemount 708 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.
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.
Each power module contains one “D” size primary lithium battery. 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.
