Maintenance

Risk of electric shock
Working on the industrial PC while it is live can lead to electric shock.
• Turn off the supply voltage before cleaning the device or replacing device components. This does not
apply to the replacement of hard disks and SSDs in a RAID configuration.
Maintenance measures increase the efficiency of the device by ensuring long-term functionality. Cleaning
and maintenance of certain device components and the replacement of other device components contribute
to this.
7.1

Cleaning

Unsuitable cleaning agents
The use of unsuitable cleaning agents can damage the device.
• Only clean the industrial PC as specified.
It is essential to observe the following aspects when cleaning the industrial PC:
• Observe to the boundary conditions of protection rating IP50/IP20.
• Only use a vacuum cleaner to clean the PC. The industrial PC does not have to be switched off for this.
• Never use compressed air to clean the PC.
• Maintain an ambient temperature range of 0 °C to 55 °C.
7.2 Maintenance
Use of incorrect spare parts
The use of spare parts not ordered from Beckhoff Service can lead to unsafe and faulty operation.
• Only use spare parts that you have ordered from Beckhoff Service.
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.
These are the following components:
• Battery
• Storage media
• Fan
The following table provides recommendations for the regular, precautionary replacement of the PC
components:
