are permitted for the use in hazardous locations.
Aluminium diecast
is generally excluded for hazardous locations.
Couplings for the use in hazardous locations are marked on at least one component completely and on the
remaining components by an
label on the outside diameter of the hub or on the front side each for the
operating conditions permitted. The flexible spider or DZ element is excluded. For reason of limited space only the
symbol
is stamped up to size 19.
