Beckhoff is excluded from liability in the event of possible damage occurring during maintenance work. In
order to avoid damage caused by electrostatic discharge when replacing device components, protective
measures are recommended. Below are some suggestions.
ESD protection
Electrostatic discharge
The replacement of device components without ESD protection can lead to functional impairment and
destruction of the device.
• If possible, apply ESD protection measures during maintenance work.
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 device and create an ESD-protected environment in which existing electrostatic charges are
safely discharged to ground 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:
• Use conductive mats connected to the ground potential as underlays.
• Dissipate possible charges from your own body by touching grounded metal (e.g. control cabinet door).
• Wear a wrist grounding strap.
• Only remove new electronic components from the ESD packaging (tinted plastic bag) after putting on
the wrist grounding strap.
• Do not walk around with electronic components in your hand if they are not in ESD packaging.
Access to device components
To be able to replace the battery and the storage medium, you must first gain access to these device
components. The battery and storage medium are accessible from the bottom of the panel PC. The device
components are located behind a cover. Loosen the two M3 screws to gain access to the battery (1) and
storage medium (2) (see Fig. 21).
