1)
When the instrument is powered by an external voltage supply, make sure the voltage supply unit has a suf-
ficient current carrying capacity. With a voltage supply <9.6 V, current peaks of up to 2 A must be expected.
2)
The listed power specifications include the voltage supply of a HART sensor with 20 mA.
3)
The listed energy requirement includes the voltage supply of a HART sensor (VEGAPULS 61 with 4 mA (multi-
drop mode) and 12 V operating voltage.
