SAFETY MESSAGES Procedures and instructions in this section may require special precautions to

ensure the safety of the personnel performing the operations. Information that

raises potential safety issues is indicated by a warning symbol ( ). Refer to the
following safety messages before performing an operation preceded by this
symbol.

Failure to follow these installation guidelines could result in death or serious injury

• Make sure only qualified personnel perform the installation.

• Use the equipment only as specified in this manual. Failure to do so may impair
the protection provided by the equipment.

Explosions could result in death or serious injury

• Verify that the operating environment of the transmitter is consistent with the
appropriate hazardous locations specifications.

• Before connecting a HART
make sure the instruments in the loop are installed in accordance with intrinsically
safe or non-incendive field wiring practices.

• To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing.

Electrical shock can result in death or serious injury

• Use extreme caution when making contact with the leads and terminals.

• Make sure the main power to the Rosemount 5300 Series transmitter or
Rosemount 5400 Series transmitter is off and the lines to any other external
power source are disconnected or not powered while wiring the transmitter.

Rosemount 5300/5400 Series

INTRODUCTION This document describes the installation procedure of a HART to Modbus

Converter (HMC) when using with Rosemount 5300/5400 transmitters.

To upgrade the Rosemount 5300 or 5400 Series transmitters, use the
modification kit together with the tools detailed below.

The Modification Kit The modification kit consists of the following parts:

• Terminal Block

• 120Ω Termination Resistor

• CSA Bracket for Grounding - only included in Modification Kit for
transmitters with CSA approval (Model Code E6)

• Spare Kit Modbus Label

• IS Ground Label

• Spare Part Kit Instruction

• HART to Modbus Manual Supplement

Figure S-1. Parts of the
Modification Kit

NOTE!

Before starting to upgrade the transmitter to use with Modbus, make sure the
transmitter head you are upgrading is eligible for the Modbus upgrade.

Transmitters with the following certificates are allowed to be upgraded to Modbus:

• transmitters with FM or CSA approval (Model Code E5 or E6)

• transmitters with no hazardous location certificates (Model Code NA)

Transmitters which cannot be upgraded to Modbus:

• transmitters with other type of approvals (for example, Intrinsic Safety
Approval). Model Codes: E1, E3, E7, I1, IA, I3, IC, I5, IE, I6, IF, I7, IG, KA,
KB, KC, KD, KE, KF, KG, KH, KI, KJ, KK, KL.

• transmitters containing Special Certifications with model code QS (Prior
Use Certificate of FMEDA)

• transmitters containing Special Certifications with model code U1 (WHG
Approval)

The model code describes what options were included when the transmitter was
ordered originally.

To find out if the transmitter is eligible for Modbus upgrade, look for E5, E6, or NA
combination in the model code.

This letter/number combination is normally found at the end of the model code.

Example Model Code 1

5301HA1S1V4AE00500AARAE5M1Q4

This model code contains E5 (FM approval) and is eligible for upgrade to Modbus.

Model Code 2

5301HA1S1V4AE00470AARAI6M1BRQ4

This model code contains I6 (CSA Intrinsic Safety approval) and is not eligible
for upgrade to Modbus.

Model Code 3

5301HA1S1V4AE00470AARAE5M1QS

This transmitter contains the E5 code (FM approval) and the QS code also (Prior
Use Certificate of FMEDA) and is therefore not eligible for Modbus Upgrade.

If unsure whether your transmitter can be upgraded to Modbus, contact your local
Rosemount Level Specialist for more information.
