Technical data according to IEC/EN 60079-7 (increased safety “ec”)
Note
The creepage and clearance distances were determined in the worst case. (with
closed or open clamping yoke) If smaller cross sections than the rated cross
section are used, the belonging lower current has to be laid down in the IECEx
/EC-Type Examination Certificate of the complete apparatus.
Mounting instructions
The WMF 2.5 DI terminal block is suitable for application in enclosures in atmospheres with flammable gases and combustible dust. For use in flammable gases these enclosures must satisfy the requirements according to EN/IEC 60079-0 and EN/IEC 60079-7. For use in combustible dust these enclosures must satisfy the requirements according to EN/IEC 60079-0 and EN/IEC 60079-31. In combination with other terminal block series and sizes and if other accessories are used, the applicable creepage and clearance distances shall be met.
Regarding the use of accessories the instructions of the manufacturer must be followed.
Schedule of Limitations
The disconnect terminal block is suitable for use in enclosures in atmospheres with flammable gases and combustible dust. For flammable gases these enclosures must satisfy the requirements according to EN/IEC 60079-0 and EN/IEC 60079-For combustible dust these enclosures must satisfy the requirements according to EN/IEC 60079-31.
The terminal blocks shall be placed inside a suitable IECEx/ATEX/UKCA certified IP54 enclosure for gas atmosphere. For dust atmosphere the terminal blocks shall be mounted inside a suitable IECEx/ATEX/UKCA certified ‘t’ enclosure (EN/IEC 60079-31).
The enclosure shall be constructed to block all sun and UV light from affecting the terminal blocks. Under normal operating conditions the temperature rise of the terminal blocks is max 40 K, measured with the max permitted rated current. Due to the above mentioned the terminal blocks may be used in apparatus of temperature classes T6…T1as long as the terminal block ambient temperature range is not exceeded as shown below. No part of terminal block must exceed 130° C under any condition.
WARNING
-
Do not remove or replace the fuse/test disconnect switch when energized!When using the types WMF 2.5 DI with other terminal blocks series or sizes or accessories, the requirements for
clearance and creepages distances according to EN/IEC 60079-7 must be observed. Regarding the use of covers, cross-connectors and end brackets the instructions of the manufacturer must be followed. -
For terminal jumper accessories current ratings and the resistances across the terminals please refer to the table under “Technical data” above.
-
The terminal can be used with either one or two wires into either side of the terminal. When two wires are used they must be of the same type, and of equal sizes. No other wire sizes or types than the ones specified in instructions must be used. The terminal blocks must either be mounted next to another block of the same type and size or with an end plate.
-
If smaller conductor cross sections than the rated conductor cross sections are used, then the corresponding lower current shall be stated in the Certificate of the complete apparatus.
-
Unused terminals shall be tightened.
-
The terminal blocks may be used, based on the self-heating when used at the nominal current and at ambient temperatures of – 60 °C to + 40 °C at the mounting position in electrical apparatus, e.g. junction and connection boxes, for temperature class T6. when the terminal blocks are used in electrical apparatus of temperature classes T1 up to T5, the highest temperature of the insulating material shall not exeed the mam. value of the operating temperature range.
- Cross connections with blank ends shall not be used.
- Manually cut cross connections shall not be used.
