Operation Manual / 2 Safety / A100-M axial1 Safety Page 8 / 17Explanations of the rating plateThe recommended replacement intervals and the corresponding operating limits are jointlydefined with the enginebuilder. This information is specific to the system.Operation above the indicated values n Bmax, t Bmax can considerably shorten the recommendedreplacement intervals. In such a case, we recommend that you contact the nearest officialservice station of ABB Turbo Systems.nMmax, t Mmax normally apply only when running at overload (110 %) during trials on the enginetest bed. These limit values can also be permitted during operation for special applications.Operation above nMmax and t Mmax is not permitted.Non-observance of the recommended replacement intervals increases the risk of unpredicta-ble component failures.Locations of the rating platesThe locations of the rating plates are defined in the Operation Manual / Product description.1.9 Periodic check of the pressure vesselsThe pressure vessels used by ABB Turbo Systems, for example, in the wet or dry cleaningprocess, are so-called simple pressure vessels. The locally applicable legal regulations regarding periodic checks of the pressure vesselsmust be observed. The operating company is responsible for the safe operation of the pressure vessel.WARNINGDanger due to pressure vesselsThe operating company must make sure the pressure vessels are in properworking condition and monitor them.
