Procedure
1. Place the Analyzer in the mounting aid supplied.
2. Carefully remove the transport protection.
3. Store the transport protection in a safe place for future use.
4. Secure the analyzer with a new copper gasket electroconductively to the vacuum chamber (CF-
flange DN 40) to ensure grounding of the analyzer as prescribed.
5. Attach the screws with the screw heads on the same side as the electronic unit to avoid impair-
ments between the black fastening nut and the analyzer installation materials.
6. For vacuum system without grounding : Prepare a grounding connector out of yellow-green or
bare copper wire (2.5 mm
2
if mechanically protected, 4.0 mm
2
if unprotected).
7. Connect the specifically marked grounding connection (M4) to the functional earth using a sepa-
rate grounding conductor.
