If a device is installed and shows an unexpected alert, verify the installation conditions.

POWER MODULE REPLACEMENT

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 power module (SmartPower Solutions, model number 701PGN green power module) then replace the power module and the cover. Ensure that the power module cover is fully tightened to prevent moisture ingress. The lip of the polymer power module cover should be in contact with 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 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 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 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.

(1)Reference conditions are 21 °C (70 °F), transmit rate of once per minute, and routing data for three additional network devices.
