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.
For cross connection accessories current rating, resistance across the terminal please refer to the table under “Technical data”
above.
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.
The fuse terminal blocks maybe used only for short circuit protecting applications based on the operational
self heating at nominal current in combination with the specified fuse links at ambient temperatures according to the following
table:
Catrige fuse-links (5 x 20 mm) **
** only permissible for sandfilled fuse

Mounting instructions:
The fuse terminal blocks are suitable for application in enclosures in atmospheres with flammable gases or combustible dust.
For use in flammable gases these enclosures must satisfy the requirements according to IEC/EN60079-0 and IEC/EN60079-7.
For use in combustible dust these enclosures must satisfy the requirements according to IEC/EN60079-0 and IEC/EN60079-31.
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 fuse terminal blocks shall be placed inside a suitable IECEx/ATEX certified IP54 enclosure for gas atmosphere. For dust
atmosphere the terminal blocks shall be mounted inside a suitable IECEx/ATEX certified
‘t’ enclosure (IEC/EN60079-31).
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.
The terminal blocks shall be placed inside a suitable IECEx/ATEX certified IP54 enclosure for gas atmosphere. For dust
atmosphere the terminal blocks shall be mounted inside a suitable IECEx/ATEX certified ‘t’ enclosure (IEC/EN60079-31).
The enclosure shall be constructed to block all sun and UV light from affecting the terminal blocks.
WARNING – Do not remove or replace the test fuse disconnect switch (AAP22 4 LI-FS) when energized!
