Guidelines For Clean Working Conditions

Even small pieces of debris can cause faults. Pay attention to the following cleanliness regulations when performing procedures.

• Thoroughly clean the connection locations/maintenance openings and the area around them prior to loosening/opening.
• Place removed parts on a clean surface and cover them with lint-free cloths.
• Carefully cover or seal opened components if repairs are not performed immediately.
• Only install clean replacement parts: remove the replacement parts from their packaging just before installing them. Do not use any replacement parts that have been kept out of packaging (for example, in a toolbox).
• Do not work with compressed air when the system is open.
• Protect the disconnected connectors from dirt and moisture and only connect when they are dry.
