Battery

An integrated battery supplies the clock block and the archive memory during
phases without power.
The battery can be specifically disconnected for storage which significantly
increases the battery life.
During power up, the SICLOCK TC 400 checks once whether the battery has
been disconnected after at least 30 minutes of operation. If required, the battery
is then automatically connected and a message output.
Service life of a disconnected battery during storage: > 12 years
Service life of a connected battery during storage: Approximately 6 years
Notice
If the battery is disconnected, hardware time and archives are lost when the
power supply for the SICLOCK TC 400 is switched off.
Note
The battery may only be replaced by the Siemens factory.
Please contact the Product Support.
