Important
To ensure proper operation of the HART communication system, a power supply with low noise and ripple must
be used. If noise or ripple on the main power source could interfere with the HART function, an isolated power
source is recommended. For additional information, refer to “Power Supply Requirements” in the Wiring section
of this manual.
