Battery configuration
The battery figures show power management information, which can be accessed via "Device"
→ "Power".
At each battery replacement the actual battery capacity is reset to 100% (parameters 508 to
510), which is then reduced with real meter consumption every 4 hours.
Power related alarm settings are located in "Alarm" group, e.g. "Battery limit" (parameter 206),
which is the level at which low power alarm is activated generating an alarm or call-up (if
configured), as well as low power fault related parameters 230 to 234.
When switching between battery power from the internal and the external battery packs,
"Battery power" (parameter 507) must be adjusted to match the actual number of batteries
connected.
