Wear Parts

Wear parts without warranty
The devices of the VSB family are basically certificated according to
• UL508 (Industrial Control Equipment) and
• C22.2 No. 14-M95 (CSA)
However, it is possible that there are combinations or extension stages
with restricted or missing certification. Thus, verify the registration
according to the UL marking on the device.
Note: To guarantee an UL/CSA-compliant operation, you have to
fulfill the following conditions:
• Use 60/75 °C copper wire only.
• Use Class 1 wire only or equivalent.
Note: The UL/CSA marking is only valid for the device in its delivery
status. After having modified the device, e. g. after plugging-in
additional extension cards, the UL compliancy has to be
verified.
CMOS battery: 5 to 7 years
• 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. 4-6: 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.
• 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
