10 Servicing explosion-protected
devices
If a part of the device on which the explosion
protection is based needs to be serviced, the
device must not be put back into operation
until a qualified inspector has assessed it ac-
cording to explosion protection require-
ments, has issued an inspection certificate or
given the device a mark of conformity. In-
spection by a qualified inspector is not re-
quired if the manufacturer performs a rou-
tine test on the device before putting it back
into operation. Document the passing of the
routine test by attaching a mark of conformi-
ty to the device. Inspection by a qualified in-
spector is not required if the manufacturer
performs a routine test on the device 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 components by the
manufacturer.
Devices that have already been operated
outside hazardous areas and are intended
for future use inside hazardous areas must
comply with the safety requirements
placed on serviced devices. Before being
operated inside hazardous areas, test the
devices according to the specifications for
servicing explosion-protected devices.
