Power module replacement
Expected power module life is ten years at reference conditions.
Note
Reference conditions are 21 °C (70 °F), transmit rate of once per minute, and routing data
for three additional network devices.
Procedure
1. Remove the power module cover and power module (SmartPower
™
Solutions,
model number 701PGN Green Power Module).
2. Replace the power module and the cover.
3. Ensure the power module cover is fully tightened to prevent moisture ingress. The
lip of the polymer power module cover contact the surface of the polymer
enclosure to ensure a proper seal. Do not over tighten.

Handling considerations
The green power module contains one “D” size primary lithium/thionyl chloride battery.
Each battery contains approximately 5.0 grams of lithium. Under normal conditions, the
battery materials are self-contained and not reactive as long as the batteries and battery
pack integrity are maintained. Be careful to prevent thermal, electrical, or mechanical
damage. Protect contacts to prevent premature discharge.
CAUTION
Use caution when handling the power module; it may be damaged if dropped from
heights in exceeding 6.1 meters (20 feet).
Battery hazards remain when cells are discharged.
Environmental considerations
As with any battery, local environmental rules and regulations should be consulted to
properly manage spent batteries. If no specific requirements exist, recycling through a
qualified recycler is encouraged. Consult the materials safety data sheet for battery-
specific information.
Shipping considerations
The unit was shipped without the power module installed. Remove the power module
prior to shipping.
Each power module contains one “D” size primary lithium battery. Primary lithium
batteries are regulated in transportation by the U. S. Department of Transportation, and
are also covered by the International Air Transport Association (IATA), International Civil
Aviation Organization (CAO), and European Ground Transportation of Dangerous Goods
(ARD). It is the shipper’s responsibility to ensure compliance with these or any other local
requirements. Consult current regulations and requirements before shipping.
