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 qualied inspector has assessed it
according to explosion protection requirements, has issued an inspection certicate, or given
the device a mark of conformity. Inspection by a qualied inspector 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 specications for servicing explosion-protected devices.
Maintenance, calibration and work on equipment
Î Only use intrinsically safe current/voltage calibrators and measuring instruments for in-
terconnection with intrinsically safe circuits to check or calibrate the equipment inside or
outside hazardous areas.
Î Observe the maximum permissible values specied in the certicates for intrinsically safe
circuits.
Referenced standards and regulations
