The operation out of this typical conditions is permissible, whereby, however,
the service life of the hard disk may reduce. However, the ambient conditions
specified for the overall device in chapter
page 18
have to be absolutely kept.
Additionally, for a Mean time between failures (MTBF) of 300,000 hours the
operating hours (power on hours) must be limited to 250 hours/month or 3,000
hours/year. Detailed information regarding the exchange of the hard disc can
be found under
chapter 8.2 "Hard Disc" on page
Also fans are mechanic wear components, whose service life is extremely tem‐
perature-dependent. For the two fans the manufacturer specifies the following

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.
