DANGER
Danger to life caused by electric voltage on the analyzer
During operation, dangerous voltage is present on the electrode system of the QMA analyzer. In un-
favorable conditions, other parts installed in the vacuum chamber (e.g. gauges) may be exposed to
this, and become dangerous to touch. (Also take into account lines and connected devices) You must
arrange or protect these installed parts so that no contact, galvanic connection, flashover, or charge
carrier flow can occur.
► Make sure that the QMA, vacuum chamber, and entire apparatus always have a proper connec-
tion to protective earth.
► Provide additional protection if the user can touch the analyzer when the vacuum system is open.
► Ensure mechanical protection against contact of the analyzer and the parts installed.
► Ensure compulsory separation of the current supply when opening the system (e.g. using a door
contact).
DANGER
Danger to life due to electric voltage
High voltages are present inside the device. When touching parts that are live, there is a risk of
death. If there is visible damage, there is a risk of death when commissioning the device.
► Work on the open device must only be carried out by trained specialist personnel.
► Before carrying out any installation and maintenance work, switch the device off and disconnect
it from the current supply.
– After switching off, wait about 60 seconds and then disconnect all cables (power cable at the
end).
► Never open the device with the current supply connected.
► Secure the current supply against unauthorized or unintentional reactivation.
► Do not insert any objects into the vent openings.
► Never open an external power supply pack.
► Never operate an open or defective device.
► Secure a defective device against accidental operation.
► Protect the device against moisture.
DANGER
Danger to life from electric shock
Inadequate or incorrect grounding of the unit leads to contact-sensitive voltage on the housing. When
making contact, increased leakage currents will cause a life-threatening electric shock.
► Before the installation, check that the connection leads are voltage-free.
► Conduct the electrical connection in accordance with locally applicable regulations.
► Make sure that the local mains voltage and frequency match rating plate specifications.
► Make sure that the mains cable and extension cable meet the requirements for double isolation
between input voltage and output voltage, in accordance with IEC 61010 and IEC 60950.
► Use only a 3-pin mains cable and extension cable with properly connected protective earthing
(earthed conductor).
► Plug the mains plug into a socket with earthing contact only.
► Always connect the mains cable prior to all other cables, to ensure continuous protective earth-
ing.
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.
