5.1 Installing QMG 700 overall system
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. Com-
ponents in the vacuum system are dangerous to touch under certain conditions. There is danger to
life due to electric voltage.
► Protect installed parts, connected units and lines against galvanic connections, flashover or
charge carrier flow.
► Make sure that the QMA, vacuum chamber, and entire apparatus always have a proper connec-
tion to protective ground.
► 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 (using a door con-
tact, for example).
NOTICE
Damage to the analyzer caused by external voltages and magnetic fields
Never expose the analyzer electrode system to external voltages that are hazardous in the event of
contact, as a result of galvanic connections, contact, flashover, plasma, ion or electron beams, etc. If
such danger sources exist in the vacuum chamber, you must provide protective measures that safely
rule out such influences. Even smaller external voltages acting on the analyzer will lead to damage to
the electronics and unreliable measuring results.
► Meet appropriate protective measures against external voltages (for example, better arrange-
ment, shielding, earthing, etc.).
► Do not mount the analyzer near to magnetic fields with > 0.2 mT.
► Ensure mechanical protection against contact of the analyzer and the parts installed.
► Ensure compulsory separation of the current supply when opening the system (using a door con-
tact, for example).
► Observe the standards applicable for the vacuum system.
Prerequisite
● Mains switch of QMS 700 set to OFF
Installing overall system
1. Mount peripheral assembly groups such as analyzer, HF stage, etc. according to the specifica-
tions in the respective operating instructions.
2. Ground all equipment involved to a single point according to the regulations.
– The only exception is the connected PC.
3. It is best to use a single mains distributor.
5.2 Installing system chassis
NOTICE
Damage caused by overheating
The ambient temperature must not exceed the permissible operating temperature of the device.
► Make sure there is unobstructed circulation of air when installing the device.
► Periodically check and clean the installed air filter, if necessary.
NOTICE
Loss of control cabinet protection class
As a built-in unit, the device can negate the required protection class (protection against foreign mat-
ter and water) of control cabinets according to IEC 60204-1, for example.
► Take suitable measures to reestablish the required protection class.
