Instruction and Operation Manual for ATEX Approved Load Cells 2.4 Advice for Interconnections a) Follow and respect the formation-regulations of the application-country. E.g. in Germany follow the regulations EN 60079-14 and EN 61241-14. b) It is ONLY permitted to use approved safety barriers or switch amplifiers for explosive-areas. In Europe, it is a requirement to have an EC-Type Examination Certificate from a nominated certifying body for the Zones 0 / 1 / 20 / 21.
Instruction and Operation Manual for ATEX Approved Load Cells 2.7 Special notes to the relative inductance and capacities of cables within intrinsically safe circuits Up to a cable length of 10 meters, the inductance and capacitance of the load cell cables are negligible. The cable lenght is shown as ZZ within the type code. In case the load cell cable lenght exceeds 10 meter, the inductance and capacitance have to be considered. Following default values can be used (according article 12.2.2.
