Component is not intended to be used alone and requires additional consideration when incorporated into other equipment or systems for use in explosive atmospheres (refer to IEC 60079-0)

Ex system combined with EMC has yellow marking on the front face (see EMC instructions)

Correct and safe installations

To achieve the highest standard of safety, a cable or pipe transit must be installed correctly. As there are many different types of frame – which may be either welded, bolted or glued into position – and insert block, it is essential that installers known when to use the most appropriate installation method.

For more information, please view following instructions, videos or download manuals as PDFs.

Components Ex

Ex and ATEX requirements are very strict, some Ex Insert blocks may not be approved with certain systems.

Insert Blocks combined with EMC has yellow marking on the front face (see EMC instructions)

Use bolts for this transit

This transit was designed for areas where welding is prohibited or welding induced stress levels making welding unacceptable. This transit is therefore to be fastened by bolts to ensure installation quality.

The transit is made of two angle bars 60x6 and two gables in galvanized mild steel.

Standard frames come in eight sizes: 1, 2, 3, 4, 5, 6, 7, and 8.
The internal width can be 60.5 ± 1 (Size 1,3,5,7) or 120.5 ± 1 (2,4,6,8).

Can be installed in horizontal combinations.

Note that there can be limitations in type-approvals & certificates, making certain sizes inapplicable

Please see information drawings for detailed data.

General

The system consists of a frame, rubber blocks and a compression unit. The frame is casted or bolted to a Ex hazardous structure and packed with rubber blocks suited for each cable and pipe dimension. The compression unit is inserted to compress the rubber blocks against cables and pipes to establish a tight seal.

Also available with EMC.
