4.2.6 Power Connection of sensor

If the sensor is used with a 4-wire transmitter
(M400 / M800), the Sensor is powered over the trans-
mitter. In this case no additional Power Supply is
needed.
For installation with 2-wire and BUS-Transmitters
(M400/2(X)H; M400 FF; M400 PA) and for direct
integration with nA, mA and Modbus an additional
power supply is required.
Power Supply Specification: 24 VDC; 500 mA
In Explosion proof applications the power supply must
comply the specifications accordingly.
Mettler Toledo offers a current limited Powers Supply
for use in Exi environment (see chapter 9).
