Around another 100 activations are possible after a

5.2. Backup battery

A discharged backup battery may lead to the internal clock
stopping in SmartRelays. We therefore recommend check-
ing the time on the clock at regular intervals. A backup bat-
tery will last for about ten years if the power supply to the
SmartRelay is not interrupted. This battery should be re-
placed on a periodical basis if SmartRelay draws on the
backup battery at regular intervals due to frequent power
failures.
NOTE
The backup battery must not be used if SmartRelay
is powered by a battery (SREL.BAT).
