Chapter 4 Installation and Wiring

4.1 Installation Requirements

Layout of control cabinet

The power supply and control parts are arranged separately

Steel plate partitions can be used to reduce interference

Ensure sufficient ventilation

Ventilation requirements

Minimum distance from passive components: 50 mm

Minimum distance from active components: 75 mm

Installation steps

Place XC-303 at the far left of the system block (XC-104/204 does not require this)

Connect the XN300 module from the right side and ensure that the locking buckle is engaged with the guide rail

Push the front cover forward to ensure that the modules are securely locked together

Pull up all locking components

Tilt the system block onto the lower edge of the DIN rail

Push the system block towards the upper edge of the DIN rail and lock it downwards

4.2 Connecting terminals

Specification of wiring terminals

Type: Spring type terminal block

Wire type:

Solid wire: 0.2-1.5 mm ²

Flexible wire (uninsulated end): 0.25-1.5 mm ²

Flexible wire (with insulated end): 0.25-0.75 mm ²

AWG：24 - 16

Stripping length: 10mm

Diameter of crimping sleeve: ≤ 2.8 mm

4.3 Power Connection

XC-303 power supply

Terminal X6: V+/0V, 24 VDC

Power the XN300 modules on the processor unit and all system buses

XC-104/204 power supply

Terminal X4: V+/0V, 24 VDC

Power the XN300 modules on the processor unit and all system buses

Local output power supply (XC-303)

Terminal X2: UL+/UL -, 24 VDC external power supply

Power supply for local output Q1-Q4

4.4 Potential relationship

XC-303

The system power supply (X6) consists of the processor, system bus CAN、RS485、 Power over Ethernet

Local output power supply (X2/UL) is isolated from the system power supply potential

CAN1 interface isolated from system power supply potential

XC-204

The system power supply (X4) provides power to all components

No potential isolation

4.5 EMC compatible wiring

Cable classification

Power cables: high current power lines, contactor coil lines, etc

Control and signal cables: digital input cables

Measurement and signal cables: fieldbus cables

Wiring principles

Power cables and signal cables should be routed separately as much as possible

Minimum spacing: Power cables and signal cables ≥ 10cm, and data/analog cables ≥ 30cm

The return wires of a pair of circuits should be routed in parallel

Shielding Grounding

The data interface must use shielded cables

Large area low impedance grounding at both ends of the shielding layer

4.6 Suppression Circuit

For inductive loads (contactors, relays, solenoid valves), it is recommended to install suppression circuits (RC suppressors or freewheeling diodes) directly on the load to prevent high induced voltage interference with the system during switching.

Chapter 5 Programming and Debugging Environment

5.1 Programming software

The XControl series PLC uses XSOFT-CODESYS-3 programming software (version 3.5.9 or higher). This software is based on the CODESYS V3 platform and provides complete support for the IEC 61131-3 programming language.
