2 If installed incorrectly or used for applications for which it isnot intended, however, it is possible that application-related dangers may arise, overflow or explosion in an ignition-hazardous this reason, the instrument must be installed, connected, operated andmaintained by personnel that are authorised by the user of the facility and who aresuitably qualified. The manual must have been read and understood, and theinstructions followed. Modifications and repairs to the device are permissible onlywhen they are expressly approved in the Notes on SafetySilometer FMC 4204 Endress+ General notes on safetyIn order to highlight safety-relevant or alternative operating procedures in the manual,the following conventions have been used, each indicated by a corresponding icon inthe conventionsNote!A note highlights actions or procedures which, if not performed correctly,may indirectly affect operation or may lead to an instrument response which is not !

They are also galvanically isolated from the power the powersupplyEnsure that the power voltage agrees with that stated on the nameplate on top thehousing and check the power voltage at the mounting power voltage in the instrument can be altered as required depending on theversion delivered.
