Page 4: Symbols Used
The HMX50 is suited for the connection of field devices used in potentially explosive atmospheres. Safe field circuits for these devices are intrinsically safe and are galvanically isolated from non-intrinsically safe circuits. The devices thus establish an electromagnetic separation between the potentially explosive atmospheres and the safe areas in a system. Endress+Hauser... - Page 5 In addition, two configurable limit values from the HART variables can be monitored via the relay outputs on the HMX50. More information can be found in Technical Information TI429F. For certificates, declaration of conformity please refer to webpage http://www.pepperl-fuchs.com/selector/gui/ global_search.kly?search_type=PRODNAME&action=list&que- ry=KFD2-HLC-Ex1* Endress+Hauser...

Only the manufacturer is authorised to perform reparations. Please contact the service of Endress+Hauser. Tampering with or making changes to the devices is dangerous and therefore not permitted. They render the warranty void. -

• When intrinsically safe circuits are used in areas made hazardous by dust (zone "D"), only appropriately certificated field devices must be used. • The EC-Type Examination Certificates should be observed. It is especially important to observe the "special conditions" where these are contained in the certificates. Endress+Hauser... - Page 9 When intrinsically safe circuits are used in areas made hazardous by dust (Ex zone "D"), only appropriately certificated field devices must be used. • The EC-Type Examination Certificates and the manufacturer's declaration of conformity are to be observed.
