4.8.3 Non-intrinsically safe power supply
With a non-intrinsically safe power supply in non-hazardous installations or explo-
sion-proof/flameproof installations, wire the transmitter as shown in Figure 4-7.
Note
Make sure the power supply is off when connecting the transmitter.
Figure 4-7. Wiring for Non-Intrinsically Safe Power Supply (HART)
The Field Communicator and the HART modem require a minimum load resistance of 250 :ī
within the loop to function properly.
Note
The diagram is valid only if the HART load resistance is at the + side and if the - side is grounded,
otherwise the load resistance value is limited to 435 :.
Note
For explosion-proof/flameproof installations make sure the transmitter is grounded to the I.S.
ground terminal inside the terminal compartment in accordance with national and local
electrical codes.
