Protection category “Intrinsic safety Eex i”
EEx approvals according to the ATEX guideline – 94/9/EG
DIN VDE 0106 part 100: 1983 – 03
Protection against electrical shock. Layout of operating devices
near live components
According to the installation specification DIN VDE 0165, electrical equipment installed in areas with explosion
hazard of group II, zone I (chemical and petrochemical industries) are excluded from the type test and
obligatory marking, if they do not contain any voltage source and correspond to DIN EN 50020-VDE 0170/0171
part 7. This applies in particular to feed through terminals in the standard version, as DIN EN 50020 does not
make any special demands on connector terminals of the protection category Eex i.
It has been generally accepted that feed through terminals in intrinsically safe circuits are clearly marked with
the blue coloring of the insulated housing. For intrinsically safe circuits, feed through terminals can be used in
the standard version and if required available with blue insulating housing.
(ATEX = Atmospheres Explosibles) are currently being prepared.
This guideline aims at clarifying the procedures and applications of devices, components and protective
systems to make them suitable for use in explosion hazard areas. Their proper use shall then help to eliminate
the barriers and difficulties that occur in the free exchange of goods within the European Community.
The transition period between EEx approvals and the ATEX guideline will last until June 30, 2003.
The standard cited in the Accident Prevention Regulation VBG 4 is seen as the basis for the layout of
electrical equipment up to 1000 V
devices are arranged near live components that are operated by at least electrotechnically instructed persons
(occasional handling).
A protected zone is established for this purpose which must be reached into on “occasional handling” of the
operating device (switch, push button, rotary button). A distance of
– 30 mm around the operating device “safety from finger touch” and
– 100 mm around the operating device “safety from touch by the back of the hand”
is designed and required.
The VBG 4 regulation is directed at the installer or user of electrical installations who must plan, build and
finally operate the installation in accordance with accident prevention regulations. The installer has the task of
selecting electrical equipment with the objective and if necessary making it safe to touch using accessories.
Only he can confirm that his installation conforms to the accident prevention regulation VBG4.
Wieland develops, builds and tests its products according to the relevant equipment and safety regulations
that are likewise cited in regulation VBG4 and moreover offers a range of accessories that takes this
requirement into account.
