CHAPTER 1: SAFETY / COMPLIANCE
1.1 Safety Warnings and Guidelines
When found on the product, the following symbols specify:
a. All applicable codes and standards need to be followed in the installation of this product.
b. For I/O wiring (discrete), use the following wire type or equivalent: Belden 9918, 18 AWG
or larger.
.
.
WARNING –EXPLOSION HAZARD –Do not disconnect equipment unless power has been
switched off or the area is known to be non-hazardous.
WARNING –To avoid the risk of electric shock or burns, always connect the safety (or earth)
ground before making any other connections.
WARNING –To reduce the risk of fire, electrical shock, or physical injury, it is strongly
recommended to fuse the voltage measurement inputs. Be sure to locate fuses as close to the
source as possible.
WARNING –Replace fuse with the same type and rating to provide protection against risk of fire
and shock hazards.
WARNING –In the event of repeated failure, do not replace the fuse again as a repeated failure
indicates a defective condition that will not clear by replacing the fuse.
WARNING –EXPLOSION HAZARD –Substitution of components may impair suitability for Class
I, Division 2.
WARNING - The USB parts are for operational maintenance only. Do not leave permanently
connected unless area is known to be non-hazardous.
WARNING –EXPLOSION HAZARD - BATTERIES MUST NOT BE CHANGED.
WARNING –BATTERY MAY EXPLODE IF MISTREATED. DO NOT RECHARGE, DISSASSEMBLE, OR
DISPOSE IN FIRE.
WARNING: Only qualified electrical personnel familiar with the construction and operation of
this equipment and the hazards involved should install, adjust, operate, or service this
equipment. Read and understand this manual and other applicable manuals in their entirety
before proceeding. Failure to observe this precaution could result in severe bodily injury or loss
of life.

MAN1078-08-EN_RCC_UM
August 6, 2021 Page 9of 97
Adhere to the following safety precautions whenever any type of connection is made to the
module.
a. Connect the green safety (earth) ground first before making any other connections.
b. When connecting to electric circuits or pulse-initiating equipment, open their related
breakers. Do not make connections to live power lines.
c. Make connections to the module first; then connect to the circuit to be monitored.
d. Route power wires in a safe manner in accordance with good practice and local codes.
e. Wear proper personal protective equipment including safety glasses and insulated
gloves when making connections to power circuits.
f. Ensure hands, shoes, and floors are dry before making any connection to a power line.
g. Make sure the unit is turned OFF before making connection to terminals. Make sure all
circuits are de-energized before making connections.
h. Before each use, inspect all cables for breaks or cracks in the insulation. Replace
immediately if defective.

- Configurable serial protocols for communication to drives, PLCs, or other serial
peripherals
- Advanced high speed I/O capabilities
- Cscape programming software that allows all aspects of the RCC to be programmed
and configured from one integrated application
- On board Ethernet port (10/100Mbps) for Cscape programming and application defined
communication, with Auto MDI/MDI-X
- WebMI and Push capabilities for access from the Internet
- Small, compact, din-rail mountable logic controller with flexible built in I/O

CHAPTER 3: MECHANICAL INSTALLATION
NOTE: The datasheet is the first document to refer to for information related to RCC models
such as pin-outs, I/O and general specification, and other key installation information. Visit the
Horner websites to obtain datasheets, user documentation, and updates.
3.1 Overview
The mechanical installation greatly affects the operation, safety, and appearance of the system.
Information is provided to mechanically install the unit such as cutout sizes, mounting
procedures and other recommendations for the proper mechanical installation of the unit.
3.2 RCC Dimensions
Figure 3.1 –RCC Dimensions

MAN1078-08-EN_RCC_UM
August 6, 2021 Page 13 of 97
3.2 RCC Installation
These RCC modules are suitable for use in the Class I, Division 2, Groups A, B,C and D
Hazardous Locations only. The operating temperature range is -10˚Cto +60˚C.
WARNING - EXPLOSION HAZARD - DO NOT DISCONNECT EQUIPMENT
UNLESS POWER HAS BEEN SWITCHED OFF OR THE AREA IS KNOWN TO BE
NON-HAZRDOUS.
ATTENTION - RISQUE D’EXPLOSION - NE DÉBRANCHEZ PAS L’ÉQUIPEMENT
SAUF SI L’ALIMENTATION A ÉTÉ COUPÉE OU SI LA ZONE N’EST PAS
DANGEREUSE.
Devices shall be installed into an enclosure suitable for the environment that is
only accessible with the use of a tool.
1. The RCC modules conveniently mount on a DIN rail.
2. Be sure the DIN rail is in a horizontal position before installing the unit.
3. The orientation shown to the right is necessary to prevent the unit from
slipping off the DIN rail.
4. Align the unit on the DIN rail then push the DIN rail clip until it clicks into
place. Check to ensure that the unit is secure on the DIN rail.
5. Do NOT mount the unit on its side as this may cause the unit from slipping
off the DIN rail.
NOTE: The spade connector for grounding and the DIN rail clip add to the
overall measurements. The CAN/PWR and LAN connectors also add to the
measurements.
NOTE: Screw holes and a spade connector are available for a mounting option.

MAN1078-08-EN_RCC_UM
August 6, 2021 Page 14 of 97
3.3.1 Temperature / Ventilation
Ensure that the DIN Rail layout design allows for adequate ventilation and maintains the
specified ambient temperature range. Consider the impact on the design if operating at the
extreme ends of the ambient temperature range. For example, if it is determined that a
cooling device is required, allow adequate space and clearances for the device in the panel
box or on the panel door if DIN rail is mounted inside.
3.3.2 Orientation
RCC should be mounted with locking DIN tab facing down.
3.3.3 Noise
Consider the impact on the panel layout design and clearance requirements if noise
suppression devices are needed. Be sure to maintain an adequate distance between the RCC
and noisy devices such as relays, motor starters, etc.
For details on output protection, especially when using contactors and solenoids see
MAN0962.
3.3.4 Shock and Vibration
The RCC has been designed to operate in typical industrial environments that may inflict some
shock and vibration on the unit. For applications that may inflict excessive shock and vibration
please use proper dampening techniques or relocate the RCC to a location that minimizes
shock and/or vibration.

MAN1078-08-EN_RCC_UM
August 6, 2021 Page 15 of 97
CHAPTER 4: ELECTRICAL INSTALLATION
NOTE: The datasheet is the first document to refer to for model-specific information related
to RCC models for key installation information. Visit the Horner websites to obtain datasheets,
user documentation, and updates.
4.1 Grounding Definition
Ground: The term ground is defined as a conductive connection between a circuit or piece of
equipment and the earth. Grounds are fundamentally used to protect an application from
harmful interference causing either physical damage such as by lightning or voltage
transients or from circuit disruption often caused by radio frequency interference (RFI).
Grounding is also for the safety of the user.
4.2 Ground Specifications
Ideally, a ground resistance measurement from equipment to earth ground is 0Ω. In reality, it
typically is higher. The U.S. National Electrical Code (NEC) states the resistance to ground
shall not exceed 25Ω. Horner APG recommends less than 15Ωresistance from our equipment
to ground. Resistance greater than 25Ωcan cause undesirable or harmful interference to the
device.

MAN1078-08-EN_RCC_UM
August 6, 2021 Page 16 of 97
4.3 How to Test for Good Ground
In order to test ground resistance, a Ground Resistance Tester must be used. A typical Ground
Resistance Meter Kit contains a meter, two or three wire leads, and two ground rods.
Instructions are supplied for either a two-point or three-point
ground test.
Figure 04.1 –Two-Point Ground Connection Test
To power the RCC unit, V+ and V- wires are directly wired to one of the terminal strips, similar
to what is shown below on the RCC972. Earth Ground is the auxiliary spade at the bottom.

CHAPTER 5: REGISTERS
5.1 Register Definitions
When programming the RCC, data is stored in memory that is segmented into different types.
This memory in the controller is referred to as registers. Different groups of registers are
defined as either bits or words (16 bits). Multiple registers can usually be used to handle larger
storage requirements. For example, 16 single-bit registers can be used to store a word or two
16-bit registers can be used to store a 32-bit value.
Below is a table of the type of registers found in the RCC unit.
