facts & data
Information about EX e
Technical information
• The information regarding cross sectional area and connection types pertains to unprepared wires without ferrules!
Ferrules are not necessary for secure connection. Whenever ferrules are used, make sure that the tools specified by the
manufacturer are used exclusively.
• The voltage ratings apply to the terminals in their intended application. When different products are mounted adjacent to
each other, the proper isolation distances must be adhered to.
• If the ground blocks are not used in block assemblies, but are mounted to the rail as single terminal blocks, end clamps
have to be used.
• A detailed description of technical data, the standards requirements, and the application conditions are available in the
flyer facts & DATA .
ATEX regulation

• For the use of DIN rail terminal blocks in Ex areas, the regulations of EN 60079-0 apply; whereas for increased safety Ex e
the regulations of EN 60079-7 must be followed. For an approximation of the laws of the EU member states, directive
94/9/EG was created, which is generally known as ATEX 100a and which is the basis for harmonization in this field.
ATEX stands for ”atmoshpere explosive” while 100a refers to the corresponding article of the EC contract.
• Directive ATEX 100a applies for protection against dust and gas explosions in all industrial Ex areas and in mining.
The testing and certificating institutes named in directive ATEX 100a must follow accreditation procedures which are the
same throughout Europe.
• In accordance with EN 60070-0/60079-7 and ATEX 100a, these certifying institutes write out EC certificates for proto­
type tests. These prototype test certificates for components together with the corresponding quality system certification
of the supplier are required to obtain the so-called ATEX approval.
• In combination with the  mark, the markings of the Wieland terminal blocks have the following meaning:
 Identification

ATEX... Certifcate, year of testing, number
Mounting instructions for Ex e applications
• If feed-through blocks are mounted directly adjacent to other feed-through blocks of a different size, or directly adjacent
to ground blocks, the open side of the block group of the same type must be covered by an end plate or partition.
• If adjacent DIN rail terminal blocks are jumpered or if jumpered DIN rail terminal blocks are positioned next to
unjumpered DIN rail terminal blocks, a partition plate must be inserted between the individual terminal block groups or
at the beginning and end of a laterally or longitudinally connected terminal block (group) in order to meet the specified
isolation distances. Notched out and jumpering cross connectors can not be used in Ex areas.
• If the terminal blocks are combined with other certified series and sizes and when their accessories are used, the
required creepage distances and clearances must be adhered to.
• The feed through terminal blocks and protective conductor terminal blocks are suitable for enclosures for use in
explosive gas atmospheres or for use in the presence of combustible dust. For explosive gas atmospheres these
enclosures must satisfy the requirements of EN 60079-0 and EN 60079-7. For combustible dust these enclosures must
satisfy the requirements of EN 61241-0 and EN 61241-1 rather EN 50281-1-1.
• If the DIN rail terminal blocks are installed in a housing with protection type “e” (increased safety) according to
EN 60079-7, the clearances and creepage distances stated in Table 1 must be adhered to..
• The indicated values for the current carrying capability refer to a maximum ambient temperature of 40 °C. When the
terminal blocks are loaded with the maximum rated current the temperature rise will be max. 45 K.
• Operating temperature range: -40° C ... +80° C, series WK(N)/M..., WKF -20° C ... +80° C, series WKFN
• If cables are used whose cross-section is smaller than the nominal cable cross-section, the corresponding lower current
must be specified in the EC prototype test certificate for the complete device.
• Due to the heat generated during operation at the specified current and at ambient temperatures of ≤ 40 °C, the DIN
rail terminal blocks can be installed in equipment (mainly distribution and connection boxes) suitable for temperature
class T6. If DIN rail terminal blocks are installed in equipment with a temperature class ranging from T1 to T5, it must
be ensured that the maximum temperature of the insulating parts does not exceed the maximum value in the operating
temperature range.
