7.2 Maintenance
Beckhoff Industrial PCs are manufactured from components of the highest quality and robustness. They are
selected and tested for best interoperability, long-term availability and reliable function under the specified
environmental conditions.
Nevertheless, some components of the Industrial PC may be subject to a limited service life if they are
operated under certain conditions, such as more demanding ambient conditions during operation or during
storage, or if they are out of service for long periods of storage.
Beckhoff therefore recommends replacing some of the Industrial PC components after the time after which
predictions of the remaining service life of such components can no longer be reliably calculated.
For the C7015, these are the following components:
• Battery
• Storage medium
The following table provides recommendations for regular replacement of PC components:
Table 18: Replacement recommendations for PC components
Component Recommendation for replacement intervals
(years)
UPS battery pack 5 years
2.5-inch hard disk 5 years or after 20,000 operating hours at more than
40 °C or after 30,000 operating hours at less than 40
°C
3.5-inch hard disk 5 years, irrespective of the operating hours
Fan 7 years
Compact Flash, CFast or SSD 10 years
Motherboard battery 5 years
Device components may only be replaced by Beckhoff. Contact Beckhoff Service (see Chap. 10.1 Service
and support [

ESD protection
NOTE
Electrostatic discharge
Working on the Industrial PC without ESD protection can lead to functional impairment and destruction of
the device.
• If possible, apply ESD protection measures when working on the Industrial PC.
When working on electronic devices, there is a risk of damage due to ESD (electrostatic discharge), which
can impair the function or destroy the device.
Protect the Industrial PC and create an ESD-protected environment in which any electrostatic charges are
discharged to the ground in a controlled manner and charging is prevented.
An ESD-protected environment can best be created by setting up ESD protection zones. The following
measures serve this purpose:
• ESD-compliant floors with sufficient conductivity to the reference potential PE;
• ESD-compatible work surfaces such as tables and shelves;
• Wrist grounding strap, especially for sedentary activities;
• grounded and electrostatically dissipating equipment and operating materials (e.g. tools) within the
ESD protection zone.
If it is not possible to create an ESD protection zone, you can still protect the device against ESD damage.
For example, the following measures can be used:
