During work on and with the device, the required personal protective equipment must always be worn. Appropriate use VEGAMET 391 mit SIL-Qualifikation is a universal controller for con- nection of a 4 … 20 mA sensor. You can find detailed information about the area of application in chapter "Product description".
For applications in hazardous areas (Ex), only devices with corre- sponding Ex approval may be used. Observe the Ex-specific safety instructions. These are an integral part of the device documentation and are enclosed with every device with Ex approval. VEGAMET 391 • With SIL qualification...

Voltage supply The data for power supply are specified in chapter "Technical data". Connection cable The voltage supply of VEGAMET 391 mit SIL-Qualifikation is con- nected with standard cable according to the national installation standards. To connect the sensors, standard two-wire cable can be used. If elec- tromagnetic interference is expected which is above the test values of EN 61326 for industrial areas, shielded cable should be used.

(e.g. interruption or voltage loss), the instrument remains in unsafe and unlocked status. Warning: Instrument reset In case of a reset to basic settings, all safety-relevant parameters will also be reset to default. Therefore all safety-relevant parameters must be checked or readjusted.
