Installation Guide

■
The low battery warning allows the utility to easily identify which Cellular 500Ws are
nearing end-of-life in a mixed population and gives the utility the opportunity to schedule
replacement.
The remote modules include a battery life estimator. The estimator is based on the
number of data packets sent at the various power levels and the age (self-discharge) of
the Cellular 500W .
Note: The low battery warning is a single flag that is set when the battery has less than
10% remaining capacity, which typically corresponds to 2 years of battery life
remaining. Battery life is evaluated daily at midnight.
Network Mode
Note: Cellular 500W events and alarms are dependent on the module's firmware version.
For more information, see Firmware Functionality on page 11.
The Cellular 500W reports the tampers available in Mobile Mode as well as extended meter
