Quick Start Guide

• A cable is required for wiring between the transmitter and remote mount
LCD display. The cable length is limited to 100 ft.
• 50 ft. (option M8) or 100 ft. (option M9) cable is provided for wiring
between the transmitter and remote mount LCD display. Option M7 does
not include cable; see recommended specifications below.
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
CAUTION
Do not apply power to the remote communications terminal. Follow wiring
instructions carefully to prevent damage to system components.
