Important Safeguards
HIGH VOLTAGE (up to 480 VAC) is used in the
operation of this equipment; DEATH ON CONTACT may result if personnel fail to observe
safety precautions.
Learn the areas containing high-voltage connections when installing or operating this
equipment.
Be careful not to contact high-voltage connections when installing or operating this equipment.
Before working inside the equipment, turn
power off and ground all points of high potential before touching them.
The owner/installer must provide all necessary
safety and protection devices and follow all
current electrical wiring standards and regulations. Failure to do so may compromise the
integrity of the controller and/or cause product
failure resulting in a safety risk to operational
and service personnel.
This controller utilizes a heat sink which is designed to cool the unit during operation. Under no circumstance should air flow around the
controller be compromised in any way. Failure
to do so may result in the overheating of the
controller, product failure, product temperatures and even fire.
During continuous operation, the heat sink can
reach very high temperatures, and keeps a
high temperature even after the unit is turned
off due to its high thermal inertia.
Higher voltages may be present. DO NOT work
on the power section without first cutting out
electrical power to the panel. Failure to do so
may cause serious injury or death.
ELECTRIC SHOCK HAZARD: Any installation involving control equipment must be performed
by a qualified person and must be effectively grounded in accordance with the National
Electrical Code to eliminate shock hazard.

4. Installation – Wiring
This section covers the C4 wiring installation instructions for the power supply, inputs, outputs and interfaces.
CAREFULLY READ THE FOLLOWING WARNINGS
BEFORE INSTALLING THE INSTRUMENT!
Failure to obey these warnings could create
electrical safety and electromagnetic compatibility problems, as well as void the warranty
and cause personal injury or death.
Electrical Power Supply
• The controller DOES NOT have an On/Off switch.
The user must install a switch or isolator that conforms to all codes and electrical safety requirements
(CE mark) to cut off the power supply upstream of
the controller. The switch must be installed in the
immediate vicinity of the controller and with-in
reach of the operator. A single switch can be used
for multiple devices.
• The earth connection must be made with a specific
lead.
• If the product is used in applications with risk of
harm to persons or damage to machines or materials, it MUST be equipped with auxiliary alarm
device(s). It is advisable to provide the ability to
check for tripped alarms during regular operation.
DO NOT install the product in rooms with hazardous (inflammable or explosive) atmosphere; it may
be connected to elements that operate in such atmosphere only by means of appropriate interfaces
that conform to current safety standards..
Notes on Electrical Safety and Electromagnetic
Compatibility
CE MARKING: EMC (electromagnetic compatibility)
conformity in compliance with Directive 2004/108/
CE and following modifications. Series C4 control-
lers are mainly intended for industrial use, installed on
panels or control panels of production process machines or systems. For purposes of electromagnetic
compatibility, the most restrictive generic standards
have been adopted, as shown on the tables.
LV (low voltage) conformity Directive 2006/95/CE.
EMC compliance has been verified with respect to the
information in Tables 1 and 2.
Recommended Installation for purposes of EMC
Instrument power supply
• The power supply for the electronic instrumentation
on the panels must always come directly from a cut/
off device with fuse for the instrument part.
• Electronic instrumentation and electromechanical
power devices such as relays, contactors, solenoids,
etc., MUST ALWAYS be powered by separate lines.
• When the power supply line of electronic instruments is heavily disturbed by switching of SCR power groups or by motors, you should use an isolation
transformer only for the controllers, grounding its
sheathing.
• It is important for the system to be well grounded.
Voltage between neutral and ground must not be > 1
V and resistance must be < 6Ω (Ohms).
• If the grid voltage is highly unstable, use a voltage
stabilizer.
• In proximity of high frequency generators or arc
welders, use adequate grid filters.
• The power supply lines must be separate from instrument input and output lines.
• Supply from Class II or from limited energy sources.
Input and output connections
Before connecting or disconnecting any connection, always check that the power and control cables are isolated from voltage. Appropriate devices must be provided:
fuses or automatic switches to protect power lines.
•
Connected outside circuits must be doubly isolated.
• To connect analog or linear inputs, strain gauges,
TC, RTD, etc., you have to:
• physically separate the input cables from those
of the power supply, outputs, and power connections.
• use braided and shielded cables, with sheath-
ing grounded at a single point.
• To connect the control outputs and alarm outputs
(contactors, solenoids, motors, fans, etc.), install
RC (series of capacitors and resistors) groups parallel to inductive loads that work in AC.
(Note: all condensers must conform to VDE stan-
dards (class X2) and support voltage of at least
220Vac. Resistances must be at least 2W).
• Install a 1N4007 diode parallel to the coil of inductive loads that work in DC.
Installation Notes
Use the extra rapid fuse indicated in Table 15.1 later
in this manual, according to the wiring schematic examples and controller rating. Additionally, the applications with solid state units require a safety automatic
switch to disengage the load power line during certain
alarm events.

9. Inductive and Transformer Coupled Load Guidelines
The model C4 should not be used for Inductive or Transformer Coupled Loads. The model C4-IR is capable of being used for these types of loads. Please refer to the C4-IR Hardware Manual for more details.
10. Communications Port (Modbus RTU/RS485)
A network typically has a Master that “manages” communication by means of “commands,” and Slaves that
carry out these commands.
Parameter Default Range
ID 1 1...99
BaudRate 19.2kbits/s 1,2...57.6k bits/s
Parity None Parity/Odd Parity/None
StopBits 1 -
DataBits 8 -
C4 modules are considered Slaves to the network master, which is usually a supervision terminal or a PLC.
They are positively identified by means of a node address (ID) set on rotary switches (tens + units).
A maximum of 99 C4 modules can be installed in a serial network, with node address selectable from “01”
to “99” in standard mode in which each C4 identifies
4 zones with sequential node address starting with the
code set on the rotary switches.
C4 modules have a ModBus serial (Serial 1) and, optionally (see order code) a Fieldbus serial (Serial 2) with
one of the following protocols: Modbus RTU, Profibus
DP, CAN open, DeviceNet, and Ethernet Modbus TCP.
The ModBus RTU port 1 has the following factory settings (default):

Switches
Procedures
AutoBaud 0 0
AutoNode* A 0
The following procedures are indispensable for the
Modbus protocol. For the other protocols, see the specific manuals. The use of rotary switches (A...F) letters
is for particular procedures described in the following
paragraphs.

Section 11 Autobaud Function
11.1 Autobaud Port 1 Sequence
11.2 Autonode Sequence for Fieldbus Use Function
Adapt the serial communication speed and parity of
the C4 modules to the connected supervision terminal
or PLC. If a fieldbus card (port 2) is used then port 1
settings must remain at factory settings.
Green LED L1 “STATUS” mentioned in the procedure
can vary its behavior based on parameter Ld.1, which
is set to a default value of 16.
Procedure
1. Connect the serial cables for all modules on the network to serial 1 and to the supervision terminal.
2. Set the rotary switch on the C4 modules to be installed, or on all modules present in case of first installation, to position “0+0”.
3. Check that the green “STATUS” LEDs flash at high
frequency (10Hz).
4. The supervision terminal must transmit a series of
generic “MODBUS” read messages to the network.
5. The procedure is over when all of the green L1
“STATUS” LEDs on the C4 modules flash at a normal frequency (2Hz) (if parameter 197 Ld. 1 = 16 as
default).
The new speed parameter is saved permanently in each
C4; therefore, the “AUTOBAUD SERIAL 1” sequence
does not have to be run at subsequent power-ups.
When the rotary switch is turned, the green “STATUS”
LED stays on steadily for about 6 seconds, after which
it resumes.
11.2 Autonode Sequence for Fieldbus Use
Function
Autonode should be run for all field bus installations.
The L1 “STATUS” green LED mentioned in the procedure can vary its behavior according to the Ld.1 parameter which is 16 as default.
Procedure
1. Connect the serial cables to all the module in the
serial 1 network, disconnect supervision or C4-OP
terminals.
2. Turn the rotary switches from the set node address
to the position “A + 0”.
3. Check that the “STATUS” green LED is blinking at
an average frequency (5Hz) for 10 seconds and then
that it returns to normal blinking (2Hz).
4. Turn the rotary switches in the position of the node
address.
