Rosemount 5300 Series
4-6
Non-Intrinsically Safe
Output
With non-intrinsically safe power supply in non-hazardous installations or
Explosion-proof/Flameproof installations, wire the transmitter as shown in
Figure 4-5.
NOTE!
Make sure that the power supply is off when connecting the transmitter.
Figure 4-5. Wiring diagram for
non-intrinsically safe
installations (HART).
For HART communication a minimum load resistance of 250 within the loop
is required. For maximum load resistance. See Figure 4-1
(Explosion/Flameproof) and Figure 4-2 (Non-hazardous installations).
For Explosion-proof/Flameproof applications the resistance between the
negative terminal on the transmitter and the power supply must not exceed
435 Ohm.
NOTE!
For Explosion-proof/Flameproof installations, make sure the transmitter is
grounded to the internal ground terminal inside the terminal compartment in
accordance with national and local electrical codes.
