2 Basic safety instructions
2.1 Requirements for personnel
• Installation, commissioning, operation and maintenance of the measuring system may be
carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the specified
activities.
• The electrical connection may be performed only by an electrical technician.

2.2 Designated use
The Memosens data cable CYK10 is used for measuring with digital sensors with Memosens
technology. The Memosens extension cable CYK11 is used to connect fixed cable sensors with
the Memosens protocol and to extend CYK10-based installations.
The CYK11 cable may not be used to extend CYK10-based measuring points in the
hazardous area. The use of continuous, non-extended CYK10 Memosens data cables is
recommended for measuring points in the hazardous area.
Use of the device for any purpose other than that described, poses a threat to the safety of
people and of the entire measuring system and is therefore not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
2.3 Occupational safety
As the user, you are responsible for complying with the following safety conditions:
• Installation guidelines
• Local standards and regulations
• Regulations for explosion protection
2.4 Operational safety

correct. Ensure that electrical cables and hose connections are undamaged.
2. Do not operate damaged products, and safeguard them to ensure that they are not
operated inadvertently. Label the damaged product as defective.
3. If faults cannot be rectified:
Take the products out of operation and safeguard them to ensure that they are not
