4.2 Power module maintenance
The Smart Power Module contains two “C” size primary lithium/thionyl chloride cells. Each
cell contains approximately 2.5 grams of lithium, for a total of 5 grams in each pack.
Actual power module life can vary dramatically based on operating parameters—including
whether high-resolution data such as vibration waveforms and/or spectra are being
retrieved from the device.
Handling
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. Take
care to prevent thermal, electrical, or mechanical damage. Protect the contacts to prevent
premature discharge.
CAUTION!
Use caution when handling the power module pack. The power module pack can be damaged
if dropped from heights in excess of 20 feet.
WARNING!
Power module hazards remain even when cells are discharged.
Environmental considerations
As with any battery, consult local, national, and international environmental rules and
regulations for proper management of spent batteries. If no specific requirements exist,
you are encouraged to recycle through a qualified recycler. Consult the materials safety
data sheet for power module-specific information.
Replacement
When the power module needs to be replaced, remove the power module cover and the
power module pack. Replace the pack (P/N MHM-89002, Rosemount P/N 00753- 9220-
XXXX, or Rosemount Model # 701PBKKF) and replace the cover. Tighten to specifications
and verify the operation.
Shipping
The unit is shipped without the power module installed. Unless you are specifically
instructed to do otherwise, always remove the power module pack from the unit prior to
shipping.
The U.S. Department of Transportation, International Air Transport Association (IATA),
International Civil Aviation Organization (ICAO), and European Ground Transportation of
Dangerous Goods (ADR) regulate the transportation of primary lithium batteries
The shipper is responsible for complying with these or any other local requirements.
Consult current regulations and requirements before shipping.
