Safety instructions and measures
− 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qualiedinspectorhasassessedit
accordingtoexplosionprotectionrequirements,hasissuedaninspection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 device before putting it back into op-
eration. 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 used outside hazardous areas and are intended for fu-
ture use inside hazardous areas must comply with the safety requirements placed on ser-
viced devices. Before being operated inside hazardous areas, test the devices according
tothespecicationsforservicingexplosion-protecteddevices.
EN60079-17appliestoservicingexplosion-protecteddevices.
− Maintenance, calibration and work on equipment
The protective cable designed by SAMSON must be used when interconnecting non-in-
trinsically safe set point calibrators with intrinsically safe equipment for repair, calibra-
tion, etc. to ensure that components relevant to explosion protection are not damaged.
Observethemaximumpermissiblevaluesspeciedinthecerticatesforintrinsicallysafe
circuits.
Responsibilities of the operator
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions to the operating
personnel and to instruct them in proper operation. Furthermore, the operator must ensure
that operating personnel or third persons are not exposed to any danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
wellasthespeciedhazardstatements,warningandcautionnotes.Furthermore,theoperat-
