During work on and with the device, the required personal protective equipment must always be worn. Appropriate use VEGATRENN 142 is an [Ex ia] separator with separate power supply for connection of 4 … 20 mA/HART sensors in two-wire version. You can find detailed information about the area of application in chapter "...
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 142 •...

Mounting General instructions Mounting options VEGATRENN 142 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.
Voltage supply The data for power supply are specified in chapter " Technical data". Connection cable The voltage supply of VEGATRENN 142 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.
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 142 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.

Über die HART-Kommunikationsbuchsen kann eine Par- ametrierung der angeschlossenen HART-Sensoren ohne Unterbrech- nung des Messkreises vorgenommen werden. Der für diesen Zweck benötigte Widerstand (230 Ω) ist beim Anschluss der Klemmen 10/12 (Kanal 1) bzw. 13/15 (Kanal 2) bereits im VEGATRENN 142 integriert. Die Bedienung des angeschlossenen Sensors erfolgt über einen Windows-PC mit einer Parametrierungssoftware, wie z. B. PACTware und entsprechendem DTM. VEGATRENN 142 •...
