
Falling parts (screws, floats, etc.) may create impact sparks and lead to an explosion in
potentially explosive atmospheres. Make sure that there isn’t a potentially explosive atmosphere
and that no parts are falling when working on the visual level indicator.

When working on the visual level indicator, only use equipment and tools permitted in
accordance with the European Directive for potentially explosive atmospheres.

Polycarbonate indication rails may become statically charged – e.g. during cleaning. Sparks
created when discharging in a potentially explosive atmosphere may cause an explosion. Only
clean these parts with antistatic cleaning agents and tools.
