Replacing the power module
Expected power module life is ten years at reference conditions.
(1)
When the power module needs to be replaced, remove the power module cover and the
depleted power module. Replace the power module with a new Black Power Module,
SmartPower
™
Solutions model number 701PBKKF (part number 00753-9220-0001). Then
replace the cover and tighten it to specification. Always ensure a proper seal so that metal
touches metal, but do not overtighten.
Handling the Power Module
The Black 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 battery 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, it may be damaged if dropped from heights in
excess of 20 feet.
Battery 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 battery specific information.
