The circuit monitor uses its nonvolatile memory (RAM) to retain all data and
metering configuration values. Under the operating temperature range
specified for the circuit monitor, this nonvolatile memory has an expected life
of up to 100 years. The circuit monitor stores its data logs on a memory chip,
which has a life expectancy of up to 20 years under the operating
temperature range specified for the circuit monitor. The life of the circuit
monitor’s internal battery-backed clock is over 20 years at 25°C.
NOTE: Life expectancy is a function of operating conditions; this does not
constitute any expressed or implied warranty.
The circuit monitor standard memory is 8MB, but can be easily expanded to
16 MB, 32 MB, and higher. Contact your local Square D/Schneider Electric
representative for availability of the memory upgrade chips. The memory chip
is accessible through the access door on the side of the circuit monitor as
illustratedinFigure10–1. See the instruction bulletin provided with the
memory expansion kit for instructions on removal and installation of the
memory chip.
