Î Observe the following for servicing equipment in a section relevant for explosion pro-
tection:

equipment according to explosion protection requirements, has issued an inspec-
tioncerticateorgiventhedeviceamarkofconformity.Inspectionbyaqualied
inspector is not required if the manufacturer performed a routine test on the de-
vice before putting it back into operation. Document the passing of the routine test
by attaching a mark of conformity to the device.
– Replace explosion-protected components only with original, routine-tested compo-
nents by the manufacturer.
– Devices that have already been used outside hazardous areas and are intended
for future use inside hazardous areas must comply with the safety requirements
placed on serviced devices. They must be subjected to testing according to the
specicationsinEN60079-19.
– EN60079-19appliestoservicingexplosion-protecteddevices.
– Use the protective cable designed by SAMSON when interconnecting non-intrin-
sically safe set point calibrators with intrinsically safe equipment for repair, cali-
bration etc. to ensure that components relevant to explosion protection are not
damaged.
