2) Connect the power to the “+ PWR” terminal(left terminal) “+” and connect the
power to the PWR “-“ terminal(middle terminal) “-“ . The side that is shown
“TEST” “+” terminal should not connect to the “+” power. TEST terminal’s
connectivity will damage the Test diode.
3) Housing’s Personal Socket side to prevent moisture prevention should use
the (Conduit) to stop the connecting piece.
4) Transmitter’s power supply is supplied through the (Signal Wiring) and the
common wire should not be installed near the power line and the heavy
electric machine equipment. While connecting the common wire, the signal
loop’s one side is ground connected, and the other side is not ground
connected to the other side. The power supply “-“ side should be ground
connected.
5) To connect well, the screw terminal should be strengthened.
6) Transmitter cover closes normally.

Warning
Do not approve High Voltage (Meaning AC Power Supply) of Transmitter terminal. It
can damage the transmitter.
7) To have HART communication’s supply voltage 24Vdc, power supply and
Transmitter’s Current Loop of 250~550 ohm’s has to connect to Loop
Resistor. Refer to Figure 3.
