CAUTION
The Rosemount 928 Wireless Gas Monitor and all other wireless devices should be installed only after the Wireless Gateway has
been installed and is functioning properly. Wireless devices should also be powered up in order of proximity from the Wireless
Gateway, beginning with the closest. This will result in a simpler and faster network installation.
CAUTION
Shipping considerations for wireless products
The unit was shipped to you without the power module installed. 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 Organiation), 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.
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. Take care 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 86 °F
(30 °C).
The power module has surface resisitivity greater than one gigaohm and must be properly installed in the wireless device
enclosure. Take care during transportation to and from the point of installation to prevent electrostatic charge buildup.
WARNING
Explosions could result in death or serious injury.
• Installation of device in an explosive environment must be in accordance with appropriate local, national, and international
standards, codes, and practices.
• Review Product certifications
• Before connecting a handheld communication device in an explosive atmosphere, ensure the instruments are installed in
accordance with Intrinsically Safe or non-incendive field wiring practices.
• When connecting an external device to the Rosemount 928 Wireless Gas Monitor's discrete output in a hazardous area,
ensure that the external device is installed in accordance with Intrinsically Safe or non-incendive field wiring practices.
