2 Safety
2.1 Safety instructions
2.1.1 General safety instructions
–Only use the product in original status without unauthorised modifications.
–Only use the product if it is in perfect technical condition.
–Do not subject the product to mechanical stress.
–Before working on the product: switch off the power supply and medium supply
and secure it against being switched on again.
–Always grasp the plug by the housing. Do not pull on the cable.
–Comply with the handling specifications for electrostatically sensitive devices.
–The product can become hot during continuous operation, during operation
in block assembly and in the event of individual faults. Provide protective
measures for use and handling of the product.
–Do not operate the product in the vicinity of highly flammable media and
substances.
–Use the product indoors only.
–Use the product only in a dry environment.
–This product can generate high frequency interference, which may make it nec-
essary to implement interference suppression measures in residential areas.
–Do not exceed the maximum permissible pressure of the medium. In doing so,
take potential pressure peaks in the system into account.
2.1.2 Media
–Media may escape in the event of leakage. Take suitable protective measures
for use and handling of the product.
–When using crystallising media, plan appropriate rinsing routines for the
product.
–Use only media that will not cause dangerous reactions if mixed.
–Use only media to which the materials used for the product are resistant.
Materials in contact with the medium è 12 Technical data.
–For evaluation of the media resistance è 1 Applicable documents.
2.1.3 Return to Festo
Hazardous substances can endanger the health and safety of personnel and
cause damage to the environment. To prevent hazards, the product should only be
returned if explicitly requested by Festo.
–Consult your regional Festo contact.
–Complete the declaration of contamination and attach it to the outside of the
packaging.
–Comply with all legal requirements for the handling of hazardous substances
and the transport of dangerous goods.
2.2 Intended use
The solenoid valve VYKB is intended for installation in laboratory devices. The
product is used to control gaseous and liquid media within the limits of the
technical data. The chemical resistance of the materials of the product in contact
with the media must be tested for every application. The user is responsible for
validating the application.
–Operate the product only with a suitable sub-base. Observe the product label-
ling on the sub-base.
2.3 Foreseeable misuse
–Do not bring the product into direct contact with foods or their ingredients.
–Do not use the product for installation in medical devices.
–Do not use the product bidirectionally.
2.4 Training of qualified personnel
Work on the product may only be carried out by qualified personnel who can
evaluate the work and detect dangers. The qualified personnel have skills and
experience in dealing with electrical (open-loop) control technology.

WARNING
Risk of Injury due to Electric Shock.
• For the electric power supply, use only PELV circuits that ensure a reliable
electric disconnection from the mains network.
•Observe IEC 60204-1/EN 60204-1.
• The unit must be powered by a power source that fulfils the requirements of an
energy-limited circuit in accordance with IEC 61010-1/EN 61010-1.
–Note polarity (red cable = +).
–Observe maximum cable length of 10 m.
–Insert the plug.
