Servicing explosion-protected devices
7 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.
Inspection 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 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. Replace explosion-protected
components only with original, routine-tested
components by the manufacturer.
Devices that have already been used out-
side 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 ac-
cording to the specifications for servicing
explosion-protected devices. Observe
EN 60079-17 during servicing.
