June 2008
CSI 9420
The power module pack with the wireless unit contains two “C” size primary
lithium/thionyl chloride batteries. Each power module contains approximately
2.5 grams of lithium, for a total of 5 grams in each pack. Under normal
conditions, the power module 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.
Power module hazards remain when cells are discharged.
Batteries should be stored in a clean and dry area. For maximum power
module life, storage temperature should not exceed 30 °C.
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 CSI 9420 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 CSI 9420 and all other wireless devices should be installed only after the 1420
Wireless Gateway has been installed and is functioning properly. Wireless devices
should also be powered up in order of proximity from the 1420 Wireless Gateway,
beginning with the closest. This will result in a simpler and faster network installation.
NOTICE
Shipping considerations for wireless products (Lithium Batteries):
The unit was shipped to you without the power module installed. Please remove the power
module pack from the unit prior to shipping.
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.
