Safety instructions and measures
Servicing explosion-protected devices
Î Observe the following for servicing equipment in a section relevant for explosion pro-
tection:
– It must not be put back into operation until a qualified inspector has assessed the
equipment according to explosion protection requirements, has issued an inspec-
tion certificate or given the device a mark of conformity. Inspection by a qualified
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
specifications 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.
