Rosemount 708
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 Field Communicator in an explosive atmosphere, ensure the
instruments are installed in accordance with intrinsically safe field wiring practices.
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 (8
in.) 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 a potential electrostatic charging hazard.
Polymer enclosure has surface resistivity greater than one gigaohm. Care must be taken
during transportation to and from the point of installation to prevent a potential electrostatic
charging hazard.
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.
NOTICE
The power module with the wireless unit contains one “D” size primary lithium/thionyl
chloride battery. Each battery contains approximately 5.0 grams of lithium. Under normal
conditions, the battery materials are self-contained and are not reactive as long as the
battery 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 (86 °F).
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.
