Cleaning the enclosure
● Clean the outside of the enclosure with the inscriptions and the display window using a
cloth moistened with water or a mild detergent.

painted surface could be damaged. The inscriptions could become unreadable.
WARNING

Risk of explosion in hazardous areas if electrostatic charges develop, for example, when
cleaning plastic surfaces with a dry cloth.
● Prevent electrostatic charging in hazardous areas.

diaphragm from time to time. Use only a suitable solvent to remove the deposits from the
diaphragm. Do not use corrosive cleaning agents. Prevent the diaphragm from getting
damaged due to sharp-edged tools.
