Power is supplied by the signal wires. The Signal/Supply share one terminal(2 wires, no
additional supply wire). While you make connection, please take very carefully to make
correct connection: the "+"of Supply wires connecting with the "+" of Supply terminal
"+"on the left, signal current "-" out connecting the signal terminal "-" on the center.
The signal wire to use a shield cable or the twisted-pair couple wire can get the best
effect.
Please DO NOT let the signal wire share the same wire/cable allocation pipe or slot with
other equipment power supply wires, and the signal wire NOT close to the high-power
equipment. Using sealing element to seal the passing-hole after connecting the wires. In
case you can’t find a sealing element on site, please installing the transmitter with the
wires hole face down to prevent from entering water. The signal wire can be floating on
the ground or any one point in the signal loop grounded. The transmitter housing
grounded or not grounded are both okay.
The stability of supply voltage for transmitter is not strict, even if the voltage wave
around 1V, the influence on output signal is very small or can be ignored. The transmitter
is capacitive coupled grounded, while you are checking the insulation resistance, take care
NOT use high volts megaohm meter, only max 100V. ㏁ meter can be allowed for
checking the circuits. The maximum current for the transmitter with 4～20mA DC output
will not exceed 22mA DC.

The user can be easily through HART-CONFIG TOOL to connect with HART SMART
pressure transmitter by HART/USB interface to realize the configuration, calibration, local
controls and maintenance of HART protocol SMART pressure transmitter.
