5.1 Installing PrismaPro
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
► 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 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
► Use only a 3-pin mains cable and extension cable with properly connected protective earthing
► 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-
Impairment from contamination and damage
Touching the devices or components with bare hands increases the desorption rate and leads to in-
correct measurements. Dirt (e.g. dust, fingerprints, etc.) and damage impair the function.
► During assembly and maintenance work on high or ultra high vacuum systems, always wear
► Only use clean tools.
► Make sure that the connection flanges are free of grease.
► Remove protective caps and protective covers from flanges and connections only when necessa-
► Remove the analyzer's transport protection only when necessary.
► Carry out all work in a well lit area.
