Component:
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.

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

Cornerblocks (R20)

Standard frames come in four sizes: 2, 4, 6 and 8. They are all the same width. Height differences are shown below. The material is 10 mm (0.39”) thick.

Available as:
C20/0 R20, C30/0 R20, C40/20x20 R40, C 60/40x40, C60/0 R40

RGSC Corner Radius
Internal Radius	External Radius
R20	R30
R40	R50
R60	R70

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).

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

General

The system consists of a frame, rubber blocks and a compression unit. The frame is welded or bolted to a Ex hazardous marine 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.

The marking of the equipment and protective system:
Group II Category 2GD Ex eb IIC Gb Ex tb IIIC Db Tamb (-60°C to+70°C)
