Step 2. Connect The
Wiring
It is recommended that shielded twisted pair wiring (18-12 AWG) that is
suitable for the supply voltage and approved for use in hazardous areas be
used. For electrical information such as power supply, see diagrams and
drawings for HART
®
, FOUNDATION™ fieldbus, and Modbus on the following
pages.
To Connect the
Transmitter
1. Make sure the housing is grounded (including IS ground inside Terminal
compartment) in accordance with Hazardous Locations Certifications,
national, and local electrical codes.
2. Make sure the power supply is disconnected.
3. Remove the terminal block cover (see picture).
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 wires as illustrated on the following pages.
6. Remove the orange, protective, plastic plugs, used for transportation.
Seal any unused port with the enclosed metal plug.
7. Mount the cover and tighten the cable gland making sure the cover is
fully engaged to meet explosion-proof requirements (adapters are
required if M20 glands are used).
For ATEX, IECEx, NEPSI, INMETRO, 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.
Terminal Block
HART Communication The 5400 Series transmitter operates using a power supply ranging from
16-42.4 Vdc (16-30 Vdc in IS applications, 20-42.4 Vdc in
Explosion-proof/Flameproof applications).
The Field Communicator requires a minimum load resistance (R
L
) of 250
Ohms within the loop in order to function properly, see diagrams below.
