Power Supply and Grounding
Please refer to the Wire Diagram — Centurion C5 Controller for grounding requirements.
NOTE: Follow the instructions for protective earthing.
General Wiring Recommendation
It is essential that the following practices be adhered to.
Terminals for Safe Circuits
Terminals for intrinsically safe circuits shall be separated from terminals for non-intrinsically safe circuits by one or more of the methods given. There methods of separation shall also be applied where intrinsic safety can be impaired by external wiring which, if disconnected from the terminal, can come in contact with conductors or components.
When separation is accomplished by distance then the clearance between bare conducting parts and terminals shall be at least 50 mm.
Care should be exercised in the layout of terminals and in the wiring method used so that contact between circuits is unlikely if a wire becomes dislodged.
Section 30
2021-10-14 - 15 -
00-02-0963
Terminal Separation
When separation is accomplished by locating terminals for intrinsically safe and nonintrinsically safe circuits in separate enclosures or by use of either an insulating partition or an earthed metal partition between terminals with common cover, the following applies:
Partitions used to separate terminals shall be within 1.5 mm of the enclosure walls or alternatively shall provide a minimum distance of 50 mm between bare conduction parts of terminals when measured in any direction around the partition.
Metal partitions shall be earthed and shall have sufficient strength and rigidity to ensure that they are not likely to be damaged during field wiring. Such partitions shall be at least 0.45 mm thick or shall conform to 10.6.3 of Standard 60079-11 if of lesser thickness. In addition, metal partitions shall have sufficient current-carrying capacity to prevent burn-through or loss of earth connection under fault conditions.
Non-metallic insulating partitions shall have an appropriate CTI, sufficient thickness and shall be so supported that they cannot readily be deformed in a manner that would defeat their purpose. Such partitions shall be at least 0.9 mm thick or shall conform to
10.6.3 of Standard 60079-11 if of lesser thickness.
The clearances and creepage distances between the bare conducting parts of terminals of separate intrinsically safe circuits and to earthed or potential-free conducting parts shall be equal to 0.8 mm (for 32V “ic” clearance).
Where separate intrinsically safe circuits are being considered, the clearance between bare conducting parts of external connection facilities shall meet the following:
At least 6 mm between the separate intrinsically safe circuits.
At least 3 mm from earthed parts, if connection has not been considered in the safety analysis.

Terminal Keys, Blocks and Headers
Some keys on the terminal block are visible by the raised area and color, while others may only have the raised area. This is an example of the keys on four terminal blocks.
Key raised and color Key raised no color
IMPORTANT: Never align the Terminal keys, doing so will block proper mating of the terminal block to header.
Terminal blocks and headers are equipped with blocking-type keys. When connecting, Do Not align the key on the terminal block with the key on the header. Doing so will block proper mating of the terminals. This example shows the correct and incorrect connection.

Recommended Wiring Practice for Centurion C5 Terminal Blocks
NOTE: The terminal block must be removed from the headers on the control and any expansion modules before attempting any maintenance on the wired system or any job requiring a hot work permit. Please ensure that the work area is non-hazardous before removing or installing any terminal block. The system should also be powered off in jobs involving hot work permits, and any such instructions established by safety standards at the job site must be complied with at all times.
Use a wire size between 12 AWG (max.) and 24 AWG (min.) to connect to the terminal strip connector. Strip the insulation back 9/32 inches and twist the exposed wires tightly together.
Insert the exposed wire completely into the terminal strip and securely tighten the clamping screw. Wires must be in good condition or replaced with new wires. When running wires, take care not to damage the insulation and take precautions against later damage from vibration, abrasion or liquids in conduits. An explosion-proof conduit is not required; however, wires should be protected from damage by running them in a protective conduit or in sheaths where appropriate.

RS232 (Pins 96 – 105)
The Centurion is equipped with two RS232 communications ports. The ports are marked 96
GND1; 97 TX1; 98 RX1; 99 DTR1 and 102 GND2; 103 TX2; 104 RX2; 105 DTR2. There are also two terminals, NC and NC, that may be left unconnected or for shield termination. The
LED lights when the port is active transmitting and when the port is active receiving.
Because both ends of the RS-232 circuit depend on the ground pin being zero volts, problems will occur where the voltage between the ground pin on one end and the ground pin on the other is not zero. This may also cause a hazardous ground loop. Use of a common ground limits RS-232 to applications with relatively short cables. If the two devices are far enough apart or on separate power systems, the local ground connections at either end of the cable will have differing voltages; this difference will reduce the noise margin of the signals.

Modbus Address
With the Modbus RTU Server Address Configuration, the operator may assign a unique
Modbus address to each controller (server) unit that may be in the system. This allows the client controller to differentiate between the modules. For example, to name the controller address 21, enable the switches labeled SW1: 1, 4, and 16 (1 + 4 +16 = 21).
NOTE: The subsequent address (Address + 1) is also reserved by
Centurion, and must not be used by any other device on the Modbus network, or communication failures to devices using that address will occur due to this conflict. Counting by 2's is necessary for additional
Centurion controllers present in the system.
NOTE : Typically, this configuration is set to (1) by the factory.

Ethernet
WARNING: Explosion hazard – Do not disconnect the Ethernet port unless the power has been switched off or the area is known to be non-hazardous.
The Centurion is equipped with two Ethernet communications ports. The ports are marked
Ethernet 1 and Ethernet 2. An LED lights when the port is active transmitting or receiving a message, and an LED lights to indicate Network and Module status.
An 8P8C modular connector (often called RJ45) is commonly used on Cat 5 cables in Ethernet networks.
Twisted-pair Ethernet standards are such that the majority of cables can be wired straightthrough (pin 1 to pin 1, pin 2 to pin 2 and so on), but others may need to be wired in the crossover form (receive to transmit and transmit to receive). The Centurion can automatically detect another computer connected with a straight-through cable and then automatically introduce the required crossover, if needed with no intervention by the installer. 10BASE-T and
100BASE-TX only require two pairs (pins 1-2, 3-6) to operate. Since Category 5 cable has four pairs, the spare pairs (pins 4 –5, 7–8) in 10- and 100-Mbit/s configurations are not used.
Section 30
2021-10-14 - 33 -
00-02-0963
The Centurion uses auto negotiation, an Ethernet procedure by which two connected devices choose common transmission parameters, such as speed, duplex mode and flow control. In this process, the connected devices first share their capabilities regarding these parameters and then choose the highest performance transmission mode they both support. The
Centurion supports 10 and 100 Mbit/s over two-pair Cat5 or better cable.

WARNING: Explosion hazard
– Do not disconnect the USB port unless the power has been switched off or the area is known to be non-hazardous.
The Centurion is equipped with a USB 2.0 standard communications port. The port is marked
USB 1.
The USB 2.0 standard-A type of USB plug is a flattened rectangle that inserts into a receptacle on the USB host.
The host controller directs traffic flow to devices, so no USB device can transfer any data on the bus without an explicit request from the host controller. The throughput of each USB port is determined by the slower speed of either the USB port or the USB device connected to the port.
The Centurion connects to storage devices using a set of standards called the USB mass storage device class (MSC or UMS).

Wi-Fi (C5-1)
The Centurion C5-1(only) is equipped with a Wi-Fi communications port. The port is marked
WIFI. The Centurion allows communications directly from one computer to another without an access-point intermediary. The Wi-Fi signal range depends on the frequency band, power output, antenna gain and type. Line-of-sight is the thumbnail guide, but reflection and refraction can have a significant impact. An access point compliant with either 802.11b or 802.11g, using the stock antenna might have a range of 100 m (330 ft). Due to the complex nature of radio propagation at typical Wi-Fi frequencies, particularly the effects of signal reflection off trees and buildings, range can only be approximated for any given area in relation to a transmitter.
Wi-Fi connections can be disrupted or the internet speed lowered by having other devices in the same area. Many 2.4 GHz 802.11b and 802.11g access points default to the same channel on initial startup, contributing to congestion. Wi-Fi pollution, or an excessive number of access points in the area especially on the neighboring channel, can prevent access and interfere with other devices use of other access points, caused by overlapping channels in the 802.11g/b spectrum, as well as with decreased signal-to-noise ratio (SNR) between access points.
Important: For Entity Parameters or Power Supply and Grounding, refer to Wire Connections.
