4 Connect wiring and power up
Procedure
1. Remove and discard orange conduit plugs.
2. Remove the housing cover labeled “Field Terminals.”
Note
Do not connect the power across the test terminals. Power could
damage the test diode in the test connection. Twisted pairs yield best
results. Use 24–14 AWG wire and do not exceed 5,000 ft. (1,500 m).
For single compartment housing (Junction Box housing), shielded
signal wiring should be used in high EMI/RFI environments.
3. Connect the positive lead to the “+” terminal, and the negative lead to
the “–” terminal.
4. CAUTION
When the enclosed threaded plug is utilized in the conduit opening, it
must be installed with a minimum thread engagement in order to
comply with explosion-proof requirements. For straight threads, a
minimum of seven threads must be engaged. For tapered threads, a
minimum of five threads must be engaged.
Plug and seal the unused conduit connection with the provided
conduit plug.
5. If applicable, install wiring with a drip loop. Arrange the drip loop
so the bottom is lower than the conduit connections and the
transmitter housing.
6. Reinstall the housing cover and tighten so the cover is fully seated with
metal to metal contact between the housing and cover in order to
meet explosion proof requirements.
The figures below show the wiring connections necessary to power a
transmitter and enable communications with a hand-held Field
Communicator.

Cable type
Recommend Madison AWM Style 2549 cable. Other comparable cable may be
used as long as it has independent dual twisted shielded pair wires with an
outer shield. The power wires must be 22 AWG minimum and the CAN
communication wires must be 24 AWG minimum.
Cable length
The cable length is up to 100 ft .depending upon cable capacitance.
Cable capacitance
The capacitance from the CAN communications line to the CAN return line as
wired must be less than 5,000 picofarads total. This allows up to 50 picofarads
per foot for a 100 foot cable.
Intrinsic safety consideration
The transmitter assembly with remote display has been approved with
Madison AWM Style 2549 cable. Alternate cable may be used as long as the
transmitter with remote display and cable is configured according to the
installation control drawing or certificate. Refer to appropriate approval
certificate or control drawing in Appendix B of the Rosemount 3051S
Reference Manual for remote cable IS requirements.
CAUTION
Do not apply power to the remote communications terminal. Follow wiring
