Recommendations for local access

• Set up a physical access control for the room or control cabinet where the product is located. For example, use robust housings, locks, envelopes, or safety screws for this purpose.
• Access must only be possible for qualified personnel, for example via keys, key cards, biometric features, or special tools for access.
• Remove operator panels from the product after use.
• Safely store operator panels separately from the product.
• Access to operator panels must only be granted to authorized persons, e.g. maintenance personnel.
• To reduce the risk of unintentional changes to parameters, activate the parameter lock if available on the device.
