Note: It is considered veryunlikely that a hazardous atmosphere would be present inZone 2 at the same time that installation, maintenance orrepair work was being carried out.• Only non-flammable gases may be used for pneumatic powersupply.• Only use suited cable entries that meet the requirements ofEN 60079-15.
