    Take note of safety conformity and type approval certificates of the sensors and power instructions for Ex supply units. applications Voltage supply Power supply and current signal are carried on the same two-wire cable. The voltage supply range can differ depending on the instru- ment version. The data for power supply are specified in chapter "Technical data". Provide a reliable separation between the supply circuit and the mains circuits according to DIN EN 61140 VDE 0140-1. The VEGA power supply units VEGATRENN 149AEx, VEGASTAB 690, VEGADIS 371 as well as all VEGAMETs meet this requirement. Keep in mind the following additional influences on the operating voltage: • Output voltage of the power supply unit can be lower under nomi- nal load (with a sensor current of 20.5 mA or 22 mA in case of fault message) • Influence of additional instruments in the circuit (see load values in chapter "Technical data")
