The ambient conditions for the overall device given in chapter 4.3 "Ambient
Conditions" on page 20 have to be kept.
Solid State Drive
The SSD (Solid State Drive) shock resistance and temperature resistance is
higher compared to an ordinary hard disk. It is only subject to electrical and not
to mechanical wear.
Operating hours (power-on hours) 8760 h/year (24/7 operation)
Operating time 100% of the operating hours
Surrounding air temperature 0 °C up to 70 °C
Fig.4-7: Service life
The MTTF is a calculated value and is 2 mill. hours if the surrounding air tem‐
perature is 25 °C.
SSD is an electronic storage medium. Defragmenting is not re‐
quired. The SSD wears faster if it is often defragmented.
Fan
Fans are mechanical wear components, whose service life is extremely tem‐
perature-dependent. For the fan integrated in the housing, the following service
life is specified by the manufacturer:
Surrounding air temperature Service life
40 °C 60,000 hours
70 °C 30,000 hours

4.6 Compatibility Test
All Rexroth controls and drives are developed and tested according to the latest
state-of-the-art of technology.
As it is impossible to follow the continuing development of all materials (e. g.
lubricants in machine tools) which may interact with our controls and drives, it
cannot be completely ruled out that any reactions with the materials used by
Bosch Rexroth might occur.
For this reason, before using the respective material a compatibility test has to
be carried out for new lubricants, cleaning agents etc. and our housings / our
housing materials.
