Modular terminals for installations with explosion hazard (Ex terminals)
Protection category “Increased safety Eex e”

T
est Certificate
Ex terminals are modular terminals that have been tested and certified by a European Ex test institute in
accordance with
DIN EN 50 014 – VDE 0171 part 1
“General requirements” and
DIN EN 50 019 – VDE 0170/0171 part 6
“Protection category: Increased safety ‘e’ “
The protection category “Increased safety EEx e” applies to electrical equipment that resists sparks, electric
arcing or hazardous surface temperatures during operation. Modular terminals thus fall into temperature
category T6, in which electrical equipment at an ambient temperature of 40°C and being operated in
compliance with regulations, does not exceed the maximum temperature (surface temperature) of 85°C.
Certified test institutes are e. g. the Physikalisch Technische Bundesanstalt PTB in Germany, the Laboratoire
Central des Industries Electrique LCIE in France, the Health and Safety Executive BASEEFA in England, the
EX-Labor of ASEV in Switzerland amongst others.
However, for modular terminals used as incomplete electrical equipment, only a partial certification is issued.
This certificate is the basis for the final inspection and certification of the complete installation before it is
commissioned by an expert.
The certificate (partial certification) includes a description of the modular terminals, in which special require-
ments regarding the preparation of terminal strips are made e.g. installing separating end cover plates when
modular terminals are connected in series.
Certificates from LCIE and ASEV are available for feed through terminals of the WK... range and protective
conductor terminals of the WK...SL.. range, if indicated. The certificates identify the relevant nominal data and
include the accessories listed in the description. The areas of application are divided into:
Group I: Electrical equipment for mines with firedamp hazard
Group II: Electrical equipment for areas with explosion hazard except for mines with firedamp hazard
In accordance with a resolution of the DKE, Deutsche Elektrotechnische Kommission, terminals are also
accepted as electrical equipment for Group I (firedamp protection Eex e I) for which only the increased safety
protection type ‘e’ for Group II (explosion protection Eex e II) has been certified and vice versa.
Modular terminals with Ex protection are identified with the label EEx e I/II or EEx e II and with the approval
number. The complete test certification with a description is available upon request.
