Page 6: Safety Instructions For Ex Areas
Installations in Canada shall comply with the relevant requirements of the Canadian Electrical Code. Safety instructions for Ex areas For Ex applications, only devices with corresponding Ex approval may be used. Observe the Ex-specific safety instructions. These are an integral part of the operating instructions and are enclosed with every device with Ex approval. VEGATRENN 141 •... -
Page 7: Product Description
Principle of operation Application area VEGATRENN 141 is an [Ex ia] separator with separate power supply for connection of 4 … 20 mA/HART sensors in two-wire version. As an associated electrical device, it ensures a galvanic separation between sensor circuit and processing circuit and thus between Ex and non-Ex areas. -

Page 9: Mounting
Mounting General instructions Mounting options VEGATRENN 141 is designed for carrier rail mounting (top hat rail 35 x 7.5 according to DIN EN 50022/60715). Due to its protection rating of IP20, the instrument is suitable for mounting in switching cabinets. It can be mounted horizontally and vertically. -
Page 10: Connecting To Power Supply
Voltage supply The data for power supply are specified in chapter " Technical data". Connection cable The voltage supply of VEGATRENN 141 is connected with standard cable according to the national installation standards. Make sure that the cable used has the required temperature resist- ance and fire safety for max. occurring ambient temperature The sensors are connected with standard two-wire cable without shielding. -
Page 11: Connection Procedure
With low impedance processing systems, a resistor of approx. 230 Ω must be looped into the 4 … 20 mA cable. This resistor is already inte- grated in VEGATRENN 141 and can be chosen through the selection of the respective terminals. No additional resistor is required in the sensor circuit for direct con- nection of a HART-Master. -

The resistor (230 Ω) required for this purpose is already integrated in VEGATRENN 141 (only in case of connection of terminals 10/12). The adjustment of the connected sensor is carried out via a Windows PC with a parameter adjustment software such as e.g.
