Wear Parts

Wear parts without warranty
The devices of the VSB family are basically certified according to
• UL508 (Industrial Control Equipment) and
• C22.2 No. 142-M1987 (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, the following
conditions have to be fulfilled:
• Use insulated copper wires suitable for at least 60/75 °C.
• Use Class 1 wire only or equivalent.
Note: The UL/CSA marking is only valid for the device in its delivery
status. After modifying the device, e.g. after plugging
additional extension cards, the UL compliance must be
checked.
CMOS battery: 5 to 7 years
• The hard disk is an electromechanical 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 cycles and 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 reduce. However, the
ambient conditions specified for the overall device in chapter 4.4 have
to be absolutely kept. Different values apply for hard disks of some
devices with special design.
• Fans are mechanical wear parts whose service life depends mainly on
the temperature. For the fan integrated in the housing, the following
service life is specified by the manufacturer:
Ambient temperature
40 °C
70 °C
