Device Safety Considerations
Reading these Instructions
Before operating the device, read these instructions carefully and understand their safety implications. In some situations,
improperly using this device may result in damage or injury. Keep this manual in a convenient location for future reference.
Note that these instructions may not cover all details or variations in equipment or cover every possible situation regarding
installation, operation, or maintenance. Should problems arise that are not covered sufficiently in the text, immediately
contact Customer Support for further information.
Protecting Operating Processes
A failure of this device – for whatever reason -- may leave an operating process without appropriate protection and could result
in possible damage to property or injury to persons. To protect against this, you should review the need for additional backup
equipment or provide alternate means of protection (such as alarm devices, output limiting, fail-safe valves, relief valves,
emergency shutoffs, emergency switches, etc.). Contact Remote Automation Solutions for additional information.
Returning Equipment
If you need to return any equipment to Remote Automation Solutions, it is your responsibility to ensure that the equipment
has been cleaned to safe levels, as defined and/or determined by applicable federal, state and/or local law regulations or
codes. You also agree to indemnify Remote Automation Solutions and hold Remote Automation Solutions harmless from any
liability or damage which Remote Automation Solutions may incur or suffer due to your failure to ensure device cleanliness.
Grounding Equipment
Ground metal enclosures and exposed metal parts of electrical instruments in accordance with OSHA rules and regulations as
specified in Design Safety Standards for Electrical Systems, 29 CFR, Part 1910, Subpart S, dated: April 16, 1981 (OSHA rulings are
in agreement with the National Electrical Code). You must also ground mechanical or pneumatic instruments that include
electrically operated devices such as lights, switches, relays, alarms, or chart drives.
Important: Complying with the codes and regulations of authorities having jurisdiction is essential to ensuring personnel
safety. The guidelines and recommendations in this manual are intended to meet or exceed applicable codes and regulations.
If differences occur between this manual and the codes and regulations of authorities having jurisdiction, those codes and
regulations must take precedence.
Protecting from Electrostatic Discharge (ESD)
This device contains sensitive electronic components which be damaged by exposure to an ESD voltage. Depending on the
magnitude and duration of the ESD, it can result in erratic operation or complete failure of the equipment. Ensure that you
correctly care for and handle ESD-sensitive components.
System Training
A well-trained workforce is critical to the success of your operation. Knowing how to correctly install, configure, program,
calibrate, and trouble-shoot your Emerson equipment provides your engineers and technicians with the skills and confidence
to optimize your investment. Remote Automation Solutions offers a variety of ways for your personnel to acquire essential
system expertise. Our full-time professional instructors can conduct classroom training at several of our corporate offices, at
your site, or even at your regional Emerson office. You can also receive the same quality training via our live, interactive
Emerson Virtual Classroom and save on travel costs. For our complete schedule and further information, contact the Remote
Automation Solutions Training Department at 800-338-8158 or email us at education@emerson.com.
Ethernet Connectivity
This automation device is intended to be used in an Ethernet network which does not have public access. The inclusion of this
device in a publicly accessible Ethernet-based network is not recommended.

HART® Input/Output Channels (3HRT04/3HTSG4)
The FB3000 RTU supports a HART® (Highway Addressable Remote Transducer) module with four
(4) channels. This allows the FB3000 to communicate with external HART devices such as
transmitters.
Ensure the RTU is in a non-hazardous area. Never open the enclosure in a hazardous area.
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
Insert the 3HRT04 module in any base chassis slot except slot 1 and insert its corresponding
3HTSG4 module below it.
Note: The 3HRT04 module requires a chassis of Revision H or newer.
The 3HRT04/3HTSG4 modules cannot be used in an extension chassis.
You can configure a channel for point-to-point operation in which case it communicates with a
single HART device. Alternatively, you can configure a channel for multi-drop operation in which it
communicates with up to five (5) HART devices in parallel.

A HART input supports either point-to-point or multi-drop mode
A HART output supports only point-to-point mode; in multi-drop mode,
there is no analog signal output available.

EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.
Performing this operation in a hazardous area could result in an explosion.
Notes:
You can/remove replace any I/O module without removing power.
If you replace a 3HRT04 module with another 3HRT04 module, on insertion the new module uses
the configuration of the 3HRT04 module it replaced.
If replacing a module of a different type, for example replacing a 3MIX12 with a 3HRT04, on
insertion you will see a mismatch in FBxConnect. You will need to re-define the module in
FBxConnect as the new module type.
If you have an empty slot that has had no modules defined, on insertion the new module
assumes factory defaults and you must then configure it in FBxConnect.
1. Depress the orange tabs at the top and bottom of the 3HRT04 module to release the module
and slide it straight out of the slot.
2. Press the new replacement module into the slot until it is properly seated.
Removing/Replacing the 3HTSG4 Module
Ensure the RTU is in a non-hazardous area. Never open the enclosure in a hazardous area.
EXPLOSION HAZARD: Ensure the area in which you perform this operation is non-hazardous.

1. If you are replacing an existing personality module that is already wired with an identical
personality module, and if there is no fault with the terminal block, leave wiring connected to
the terminal block, and disconnect the terminal block from the personality module by gently
rocking the terminal block from side to side until it pops out. Conversely, if there
with the terminal block, label wires coming in so you can transfer the wires to the correct
positions on the new terminal block. To wire an all-new module, see Wiring the Module.
Detaching the Terminal Block with Wires Still Attached
is a fault
2. Using a ¼” slotted blade screwdriver, loosen the captive fastening screw at the top of the
personality module and slide the module straight out of the slot.
