(1)
When module replacement is required perform the following procedure.
5.2.1 Replace the power module
Procedure
1. Remove the cover and module.
2. Replace the module (part number 701PBKKF) and cover.
3. Tighten to specification and verify operation.
5.2.2 Handling considerations
The Black Power Module with the wireless unit contains two “C” size primary lithium-
thionyl chloride battery (Black Power Module, model number 701PBKKF). Each battery
contains approximately 5.0 grams of lithium. Under normal conditions, the battery
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.
Black Power Module should be stored in a clean and dry area. For maximum Black Power
Module life, storage temperature should not exceed 86 °F (30 °C).
Note
Continuous exposure to ambient temperature limits of –40 °F or 185 °F (–40 °C or 85 °C)
may reduce specified life by less than 20 percent.
Use caution when handling the Black Power Module, it may be damaged if dropped from
heights in excess of 20 ft.
Battery hazards remain when cells are discharged.
5.2.3 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.
5.2.4 Shipping considerations
The unit was shipped to you without the Black Power Module installed. Remove the
module prior to shipping the unit.
(1) Reference conditions are 70 °F (21° C), transmit rate of once per minute, and routing data for three additional network
devices.
