Rosemount 5300 Series with HART® to Modbus® Converter
J.2 Introduction
The Rosemount 5300 Series Transmitter is a Modbus compatible measurement device that
supports communication with a Remote Terminal Unit (RTU) using a subset of read, write,
and diagnostic commands used by most Modbus compatible host controllers. The
transmitters also support communication through Levelmaster and Modbus ASCII
protocols.
The HART to Modbus Converter (HMC) module is located inside the Rosemount 5300 Series
Transmitter enclosure and provides power to and communicates with the transmitter
through a HART interface.
Failure to follow safe installation and service guidelines could result in death or
serious injury.

Make sure the transmitter is installed by qualified personnel and in accordance
with applicable code of practice.

Use the equipment only as specified in this manual. Failure to do so may impair the
protection provided by the equipment.

Do not perform any services other than those contained in this manual unless you
are qualified.
Explosions could result in death or serious injury.

Verify that the operating environment of the transmitter is consistent with the
appropriate hazardous locations specifications.

To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing.

Before connecting a Field Communicator in an explosive atmosphere, make sure
the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.

To avoid process leaks, only use O-ring designed to seal with the corresponding
flange adapter.
Electrical shock can result in death or serious injury.

Avoid contact with the leads and terminals. High voltage that may be present on
leads can cause electrical shock.

Make sure the main power to the Rosemount
™
5300 Series Transmitter is off and
the lines to any other external power source are disconnected or not powered
while wiring the transmitter.
Probes with non-conducting surfaces

Probes covered with plastic and/or with plastic discs may generate an
ignition-capable level of electrostatic charge under certain extreme conditions.
Therefore, when the probe is used in a potentially explosive atmosphere,
appropriate measures must be taken to prevent electrostatic discharge.
