protectionisbasedneedstobeserviced,the
devicemustnotbeputbackintooperation
untilaqualiedinspectorhasassesseditac-
cording to explosion protection require-
ments,hasissuedaninspectioncerticateor
given the device a mark of conformity.
Inspectionbyaqualied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
