Data loss in the RAM during battery exchange
due to missing data backup!
WARNING
Before replacing the battery backup important data because during battery ex‐
change a voltage loss is possible, which might cause data loss in the RAM.
Charging cycles
A charging cycle is determined by switching the PC power supply unit on and
off. As long as the operator terminal is connected to the supply system, a total
discharge of the battery pack is avoided.
The number of charging cycles of the battery pack and thus, its service life is
dependent on the surrounding air temperature, in which the battery pack is
used. Surrounding air temperature defines the temperature, in which the oper‐
ator terminal and the battery pack are situated, e. g. the internal temperature
of the control cabinet or in an operator panel housing.
The following table can be used as guideline:
Surrounding air temperature
Maintenance interval
25 °C
10 years
35 °C
5 years
45 °C
2.5 years

The used batteries are recyclable and can be returned to Bosch
Rexroth after replacement. They must not be disposed in the stand‐
ard household refuse!
