CP7721-1068-0010 Membrane Keyboard Replacement

ESD protection

In order to avoid damage caused by electrostatic discharge when replacing Beckhoff HMI Keyboard CP7721-1068-0010 Operator Keyboard, protective measures are recommended. Below are some suggestions:
Protect CP7721-1068-0010 Terminal Keypad and create an ESD-protected environment in which existing electrostatic charges are safely discharged to ground and charging is prevented.
• 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 Beckhoff HMI CP7721-1068-0010 Switch Membrane 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.
