CONNECTING THE
TRANSMITTER
The Rosemount 5400 Series accepts power supplies ranging from 16 Vdc to
42.4 Vdc. It uses 4-20 mA power superimposed with a HART signal.
To connect the transmitter:
1. Make sure the housing is grounded (including IS ground inside the
Terminal compartment) according to Hazardous Locations Certifications,
national, and local electrical codes.
2. Make sure the power supply is disconnected.
3. Remove the terminal block cover.
4. Pull the cable through the cable gland/conduit. For Explosion-proof/
Flameproof installations, use cable glands or conduit entry devices
certified Explosion-proof or Flameproof. Install the wiring with a drip loop,
with the bottom of the loop lower than the cable/conduit entry.
5. Connect the wires according to Figure 4-4 for non-intrinsically safe
power supplies, and according to Figure 4-7 for intrinsically safe power
supplies.
6. Remove the orange protective plastic plugs used for transportation and
seal any unused port with the enclosed metal plug.
7. Mount the cover and tighten the cable gland, making sure the cover is
secure to meet explosion-proof requirements.
For ATEX, IECEx, NEPSI and TIIS installations, lock the cover with the
Locking screw .
8. Connect the power supply.
NOTE!
Use PTFE tape or other sealant at the NPT threads in the Cable Entries.
