DANGER

Danger to life due to dangerous contact voltage

The voltages of the IS 716 and the BIAS, TARGET and EXTR auxiliary voltages are life threatening.

► Observe the technical data of the IS 716.
► Only use professionally made cables.

DANGER

Danger to life from electric shock

The voltages under the connector plates are life threatening. Operation is not permitted if the protec-
tive pipes have been removed.

► Re-install all removed protective pipes before connecting the cables.
► Pay attention to the additional information in the corresponding chapters for special ion sources.

Risks during operation

CAUTION

Health risks and environmental damage due to the process gases used

Gases used (process gases) represent a health risk and damage to the environment.

► Check the leak tightness of the connections before introducing the process gas.
► Make sure that the exhaust gas system is suitable for the gases supplied.
► Consider potential interactions between the materials and process gases.
► When handling the gases used, observe the applicable guidelines.
► Observe the protective measures.

Risks during maintenance

WARNING

Health hazard through poisoning from toxic contaminated components or devices

Toxic process media result in contamination of devices or parts of them. During maintenance work,
there is a risk to health from contact with these poisonous substances. Illegal disposal of toxic sub-
stances causes environmental damage.

► Take suitable safety precautions and prevent health hazards or environmental pollution by toxic

process media.

► Decontaminate affected parts before carrying out maintenance work.
► Wear protective equipment.

Risks when shipping

WARNING

Risk of poisoning from contaminated products

Where products that contain harmful substances are shipped for maintenance or repair purposes, the
health and safety of service personnel is at risk.

► Comply with the instructions for safe distribution.
