• 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
Input/output cycles / month
Operating conditions
Storage conditions

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)
40 °C
70 °C

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.
