ATEX Recommendations
General Rules
Resin encapsulated products of the busbar trunking system Canalis KRA and Canalis KRC are considered as devices of group II category 3G, according to Directive 2014/34/EU Appendix I.
According to Directive 99/92/EG (ATEX 137) busbar trunking system can be used in Zone 2, as well as gas groups II A, II B, and II C, which are potentially explosive atmospheres due to flammable substances in temperature ranges of T1 to T5.
During operation or installation, the requirements of EN 60079-14:2014 have to be followed.
Resin encapsulated products of the busbar trunking system Canalis KRA and Canalis KRC, produced according to Directive 2014/34/EU Appendix I, are devices of the group II category 3D and can be used in Zone 22 according to Directive 99/92/EG (ATEX 137) and in areas of dust groups III A, III B, and III C (flammable dusts).

Special Instructions and Conditions for EX Environments
We recommend a yearly inspection of the following system components, as applicable to each individual project.
Electrostatic charging of the insulation is to be prevented in the following manner. Maintenance and cleaning work is only to be carried out after ensuring that the atmosphere is free of explosion hazard substances.
The insulation material of the entire busbar trunking system in an EX environment is to be thoroughly checked for damage and cracks.
Elements suitable for installation in EX environments have the following label:
