-Equipment inspection: After unpacking, check whether the appearance of the module is intact, whether there are any scratches or damage marks; Verify that the module model, specifications, and order requirements are consistent; Check if the interface terminals and indicator lights are intact, and if the accessories (such as fixing screws and wiring terminals) are complete.

-Tool preparation: Prepare suitable installation tools (such as screwdrivers, wrenches), wiring tools (such as wire strippers, crimping tools), and measuring tools (such as multimeters, oscilloscopes) to ensure smooth installation and debugging work.

4.2 Installation steps

1. Fixed installation: According to the module size and the installation hole position of the control cabinet, place the module steadily into the installation position, use matching screws to tighten symmetrically, and ensure that the module is firmly fixed without looseness; Avoid using metal tools to touch the module circuit board during installation to prevent static electricity from damaging components.

2. Wiring operation: Before wiring, the power must be disconnected to avoid module damage or personnel safety accidents caused by live wiring. Connect the power line, I/O signal line, and communication line in sequence according to the product wiring diagram: 

-Power line: distinguish between positive and negative poles, ensure the correct connection of 24V DC power supply, and avoid reverse connection; Suggest installing a 2A fuse at the power input end to prevent module damage caused by overcurrent; The power supply line adopts copper core cables with an area of 1.5mm ² or more to reduce the voltage drop of the line.

-Analog input line: Use twisted pair shielded cables (recommended specification 22AWG), with a single ended grounding of the shielding layer (grounding resistance ≤ 4 Ω), to avoid parallel laying with power lines and digital lines. The parallel laying time distance should be ≥ 30cm, and vertical crossing should be used for cross laying to reduce electromagnetic interference; Thermistor and thermocouple signal lines need to be laid separately to avoid mixing with other analog signal lines; Ensure good contact of the circuit during wiring to avoid signal distortion caused by false connections.

-System bus/communication line: The V-net/IP bus uses dedicated shielded cables and is wired according to the bus topology requirements, with matching resistors added to the terminals; The Ethernet line adopts standard Cat5e and above Ethernet cables, with crystal heads firmly crimped and pins correctly matched; After the completion of bus/communication line wiring, insulation testing is required to ensure that there are no short circuits or open circuits in the line.

3. Grounding treatment: The module casing must be reliably grounded with a grounding resistance of ≤ 4 Ω. The grounding cable should be a copper core cable with a cross-sectional area of not less than 2.5mm ²; It is recommended to use an independent grounding method to avoid sharing the grounding body with power equipment and prevent grounding interference from affecting the normal operation of the module.

4.3 Debugging process and key points
