NOTICE
Property damage as a result of inadequate spatial conditions
Inadequate spatial conditions will lead to property damage caused by short circuits between analyzer
and wall.
► Observe the spatial conditions required for the PrismaPro.
► Always install the analyzer in flanges or pipes featuring an internal diameter ≥ 37 mm, and where
possible > 39 mm.
► Observe the installation depth for the analyzer.
► Observe the cable bending radii.
► Do not allow kinks in the cable.
Easy access
When installing, ensure easy access to the unit to facilitate subsequent installation and
maintenance work.

5.2 Installing the analyzer
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).
