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 relevant safety standards. For
the USA, refer to OSHA rules and regulations as specified in Design Safety Standards for Electrical Systems, 29 CFR, Part 1910,
Subpart S, dated: May 16, 1981 (OSHA rulings are in agreement with the National Electrical Code). For international locations,
refer to
instruments that include electrically operated devices such as lights, switches, relays, alarms, or chart drives. The FB3000
includes a chassis ground lug. Unless specifically noted, the chassis ground is isolated from ground terminals on individual
modules installed in the device to prevent noise. The chassis ground lug provides a path to earth ground for electrical safety,
static discharge, and stray voltages. Do not connect the chassis ground lug directly to a lightning arrestor/lightning rod.
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.

Figure 1-2: FB3000 RTU – 8-Slot Version (with/without slot covers)
Emerson FB3000 RTU Instruction Manual
D301851X012
May 2022
Each slot includes an upper section and a lower section. The upper section holds the internal logic
for the module and the lower section holds the personality module used for wiring.
If your RTU is not fully populated with modules, you can fill the empty slots with slot covers to
protect the connectors from dust. These are installed/removed using the same screws used for
personality modules.
If you require more than seven I/O slots, you can optionally purchase one, two, or three extension
chassis to attach to the base chassis, allowing an additional 8, 16, or 24 I/O slots.
1.4 Central Processing Unit (CPU)
The RTU’s CPU is a Freescale (NXP) SoloX dual-core architecture processor with an Arm® Cortex
A9 core, and an Arm Cortex-M4 core. If your RTU includes multiple chassis, there is still only one
CPU module in the first slot of the first chassis; all other chassis hold only I/O modules.
There are two CPU versions available:
3CPU16 – FB3000 RTU with full control and I/O capabilities.
3IOCPU – FBxRemote I/O for I/O only with no control, no calculation support, and no
application support.

2. Press the two chassis together. If mounting on a DIN rail, slide both chassis onto the DIN rail
first to ensure proper alignment and place clamps/brackets at both ends of assembly on DIN
rail to ensure side connectors between chassis remain fully engaged. (See Section 2.6).

2.4 General Wiring Guidelines
The RTU’s pluggable terminal blocks use compression-type terminals that accommodate wire
between 24 and 12 AWG depending on the connector or terminal block and the usage. Use 28 to
16 AWG wires on the 20 pin I/O connectors; use 20 to 12 AWG wires on the power connection.
All wires must be rated for a temperature of 90oC or higher.
Wires used for power
When making a connection, insert the bare end of the wire (approx. 1/4" max) into the clamp
adjacent to the screw and secure the screw.
have a wire gauge between 20 and 12 AWG.
10 Installation
To prevent shorts, ensure that no bare wire is exposed. You can also use crimp bootlace
ferrules (18 to 24 AWG for I/O; 18 to 20 AWG for power).
Allow some slack in the wire while making terminal connections. Slack makes the wires more
manageable and helps minimize mechanical strain on the terminal blocks.
Use twisted pair, shielded and insulated cable for communication and I/O wiring to minimize
CAUTION
CAUTION
not
signal errors caused by electromagnetic interference (EMI), radio frequency interference (RFI)
and transients. When using shielded cable, ground all shields at a suitable Instrument Earth
connection point. This prevents circulating ground current loops that can cause signal errors.
See the FB3000 product data sheet for information about applicable standards for EMI and RFI
emissions and susceptibility.
To avoid damage to terminal blocks, exercise care when unplugging them. Gently pull up on one
end, then gently pull up on the other end, then continue alternating this way to gradually work
the terminal block out of its socket.
2.5 Grounding
There are four separate and distinct ground references within the FB3000 architecture. The
chassis ground lug (also known as Protective Earth or PE), internal system bus ground, isolated
ground, and the 24V loop ground.

Chassis Ground Lug
The RTU includes a chassis ground lug to the left of the power supply modules. In CSA documents,
this may be called the Protective earthing (PE) conductor. The chassis ground lug provides a path
to earth ground for electrical safety, static discharge, and stray voltage from a lightning strike.
Do
use the chassis ground lug for a direct connection to a lightning arrestor/lightning rod.
The chassis ground lug is completely isolated from the isolated, signal, and loop power ground
terminals on I/O modules, or from the 24V loop power ground terminal on some I/O modules. To
prevent noise and equipment damage, you should keep these grounds separate from the chassis
ground.

Figure 2-4: Chassis Ground Lug Location
Once you have installed the unit, run a ground wire (14 AWG protective conductor)
between the chassis ground lug and a known good earth ground.
Use stranded copper wire to earth ground and keep the length as short as possible.
Clamp or braze the ground wire to the ground bed conductor (typically a stranded
copper AWG 0000 cable installed vertically or horizontally).
Run the ground wire so that any routing bend in the cable has a minimum radius of 30.48
cm (12 inches) below ground and 20.32 cm (8 inches) above ground.
Note: If your installation includes multiple chassis, you must individually ground each chassis.
For more information on grounding or if your installation uses cathodic protection, refer to Site
Considerations for Equipment Installation, Grounding, and Wiring (D301452X012).
Internal System Bus Ground
The internal system bus ground provides an internal reference to system power negative or ground
input. Users cannot access this ground.

Isolated Ground on 3MIX12 Module
The 3MIX12 mixed I/O module includes an isolated ground system (ISOGND) on pins 5, 10, 12, and
14 of TB1. ISOGND provides a low noise return (ground) for analog inputs and outputs. It is
completely isolated from the other three ground systems. You can optionally enable grounding for
one or both digital outputs on the 3MIX12 through individual settings for each DO in FBxConnect.
When enabled, digital output(s) are internally connected to ISOGND.

24V Loop Ground on 3MIX12 Module
Pin 20 on TB1 of the 3MIX12 mixed I/O module serves as the return side of the +24V loop power
supply. It is completely isolated from the other three ground systems.

Panel or Wall Mounting the Aluminum Enclosure
To mount the RTU directly to a wall without using the DIN rail, you must first remove the mounting
plate. This exposes four holes into which you can insert screws to mount the RTU to a panel or wall.
You also need to remove I/O and personality modules to show the holes on the other side.
1. Remove I/O modules in slots 2, 3, 6, and 7.
2. Remove personality modules in slots 2 and 7.
3. Use a #2 Phillips-head screwdriver to remove the four screws that secure the mounting plate.
