• Connect a 24V DC supply to the power input terminals on the transmitter.


  • Power input terminals are labeled with 24 V DC + and – GND.


It is important to avoid ground loops in the setup / plant where the SMET is used. Ground loops can lead to excessive currents on the ground / return wire of the SMETs 24V power supply which can damage the unit.


To prevent this, we strongly recommend that the SMET is powered by a separate 24V power supply with galvanic separation. Otherwise, the SMET might be permanently damaged.
