When servicing, in particular those components
that affect the explosion protection, will have to
be checked, e. g.:
­ Housing and protective bowl for any cracks
or damages.
­ Gaskets for their perfect condition.
­ terminals and blanking plugs for their firm fit.

charge, the light fitting shall only be cleaned
with a damp, non­fibrous cloth or sponge!

liquid diluted in water as specified! The
water temperature may be max. 50 °C.
