Hard disk: The hard disk is an electromechanic wear part, that has to
be changed during the operating time. According to the manufacturer's
specifications the hard disk has been developed for a service life of 60
months in consideration of the following conditions:
Operating hours / month Max. 333
Input/output cycles / month Min. 10 and max. 150
Operating conditions Temperature 40 °C
Rel. humidity 30 %
Height < 500 m
Accesses 30 % of the operating hours
Storage conditions Temperature < 30 °C
Rel. humidity < 70 %
Duration < 3 months
Fig. 4-7: Typical operating and storage conditions of the hard disk
The operation out of this typical conditions is permissible, whereby,
however, the service life of the hard disk may be reduced. However,
the ambient conditions specified for the overall device in chapter 4.4
have to be absolutely kept.

Also fans are mechanic wear components, whose service life is
extremely temperature-dependent. For the fan integrated in the
housing the manufacturer specifies the following service life:
Ambient temperature
(surrounding air temperature) Service life
40 °C 70,000 hours
70 °C 35,000 hours

4.7 Compatibility Test
All Rexroth controls and drives are developed and tested according to the
latest state-of-the-art.
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.
