(1)
When power module replacement is required, remove the power module
cover and remove the power module pack. Replace the pack (part number
MHM-89002 or Rosemount P/N 00753-9220-XXXX) and replace the cover.
Tighten to specification and verify operation.
Handling Considerations
The power module pack with the wireless unit contains 2 “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 power module pack integrity are
maintained. Care should be taken to prevent thermal, electrical or mechanical
damage. Contacts should be protected to prevent premature discharge.
Use caution when handling the power module pack. The power module pack
may be damaged if dropped from heights in excess of 20 feet.
Power module hazards remain when cells are discharged.
Environmental Considerations
As with any battery, local environmental rules and regulations should be
consulted for proper management of spent batteries. If no specific
requirements exist, recycling through a qualified recycler is encouraged.
Consult the materials safety data sheet for power module specific information.
Shipping Considerations
The unit is shipped to you without the power module installed. Unless
specifically instructed to do otherwise, 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 International Air
Transport Association (IATA), International Civil Aviation Organization (ICAO),
and European Ground Transportation of Dangerous Goods (ARD). 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.
