Note:
If pressure transmitters are connected to HART input 2, it must be verified that the maximum
values for current and power of the ICU_HPI option board HART input 2 circuit are not
exceeding the maximum values of the connected pressure transmitters. Refer to Appendix B.
If the values of the HART input 2 circuit are too high, then connect the pressure transmitters to
HART input 1 and the 762 VITO Interface to HART input 2.
