VII. Installation and Maintenance

(1) Installation Steps

Select a location within the control cabinet that is well-ventilated, free from strong electromagnetic interference, and without corrosive gases. Secure DIN rails or prepare installation positions for the cabinet.

Align the back of the module with the DIN rails and press down until the clips are securely engaged; or fix the module on the cabinet using screw holes to ensure a secure and tight installation without loosening.

Connect the input power supply (220–240VAC) according to the terminal markings. Connect the live wire to L, the neutral wire to N, and ground the ground wire. Ensure the connections are secure and avoid loose connections.

Connect communication cables: Connect one end of the cable to the RJ45 electrical port of the module, and the other end to the electrical port of the Ovation controller/I/O module; connect the fiber optic end of one cable to the fiber optic interface of the module, and the other end to the fiber optic interface of the remote device. Ensure the fiber optic connectors are clean and the connections are tight.

If redundant configuration is required, connect the redundant interface and pair it with a redundant module of the same model to achieve dual fiber optic link backup.

After checking that the wiring is correct, connect the input power supply and observe if the green power indicator light is constantly on, if the link lights are normally illuminated, and if the module communication is normal.

(2) Daily Maintenance

Daily inspection of status indicator lights: A green light indicates normal power supply, a yellow light indicates normal link, a yellow flashing light indicates normal data reception and transmission, and a red light indicates a need to troubleshoot for fiber optic breakage, port failure, or power anomaly.

Use a dry soft cloth to wipe the surface of the module, interfaces, and heat sinks of the fins monthly. Avoid dust accumulation that affects heat dissipation and poor interface contact.

Check the looseness, oxidation, or corrosion of the connection terminals, fiber optic connectors, and RJ45 interfaces quarterly. Tighten or replace the connectors in time to avoid poor contact and communication interruption.

Avoid stacking杂物 above the module, maintain good ventilation, keep away from heat sources, water sources, and corrosive gases to prevent the module from overheating or being damaged.

In redundant configuration, manually switch the main and backup links every six months to test the redundancy switching function to ensure seamless switching in case of a failure and no data loss.

VIII. Precautions

The input voltage must strictly be controlled within the range of 220–240VAC. Do not connect it with excessive or insufficient voltage. Otherwise, the module's internal power supply and circuit will be burned out.

Fiber optic connectors must be kept clean. Avoid touching the fiber optic end faces during installation or maintenance to prevent oil stains and dust from adhering, resulting in signal attenuation or communication interruption.

During installation, ensure reliable grounding to avoid damage to the module from static electricity or leakage. Also, reduce electromagnetic interference to ensure stable communication.

Do not disassemble the module privately. There are no user-repairable components inside, and disassembly will invalidate the warranty and even cause short circuits, electric shock, and other safety accidents.

Store the module in a dry, ventilated environment without corrosive gases. Maintain a temperature range of - 40℃ to + 70℃. Avoid direct sunlight, rain, and severe vibration.

When the module fails, replace it with the original and identical model module to avoid using non-original accessories, which will affect system compatibility and communication stability.

IX. Warranty Information

Warranty period: Original and brand-new products are warranted for 12 months. Non-human-induced damage faults within the warranty period can be repaired or replaced free of charge.

Warranty scope: Covers module internal component faults, circuit faults, and communication faults; faults caused by human damage, unauthorized disassembly, overpressure use, or harsh environments (such as corrosion, water ingress) are not within the warranty scope.
