VI. Installation and Maintenance

(1) Installation Requirements

Installation location: Installed on Ovation standard I/O rack DIN rail or 19-inch rack, installed firmly and vibration-proof; reserve ≥120mm of space above and below the module and ≥60mm of space on the left and right for heat dissipation, away from strong heat sources and strong electromagnetic sources (such as frequency converters, large power motors), ensuring smooth ventilation.

Installation specifications: Install using standard snap fasteners or rack fixing components to ensure good contact between the module and the backplane; wear anti-static wristbands during installation to avoid damage to electronic components due to static electricity; when installing multiple modules in parallel, the spacing should be ≥60mm to ensure heat dissipation and signal isolation; when redundant installation is used, the spacing between the two modules should be ≥120mm to facilitate maintenance and heat dissipation. Cabling Specifications: On the input side, use a compliant AC power cable, ensuring secure connection without looseness. The live wire, neutral wire, and ground wire should be clearly distinguished. On the output side, use a multi-strand copper core DC cable with dual output positive and negative terminals connected correctly to avoid reverse polarity. All terminal connections should be tightened with a torque of 1.5–2.0 N·m to prevent loosening and overheating. The cables should be neatly arranged, kept away from strong electromagnetic interference sources, and avoid excessive bending.

(II) Maintenance Points

Regular Inspection: Monthly checks should be conducted on the module's appearance, LED status indicator lights, cooling fan operation status, and terminal connections to confirm normal input and output voltages, and absence of overheating, abnormal sounds, or looseness; review the DCS system diagnostic logs to identify potential issues such as input anomalies, output fluctuations, and fan failures.

Cleaning Maintenance: Every quarter, use a dry soft cloth or low-pressure compressed air to wipe the module surface, cooling fan, and ventilation ports, removing dust and oil stains to prevent dust accumulation from affecting heat dissipation and insulation performance; in high-dust environments, the cleaning frequency can be shortened to once a month; do not use corrosive cleaning agents or liquids for direct wiping.

Fault Troubleshooting: When the output is abnormal, first check if the input voltage is normal and if the connections are loose, then investigate if the load is short-circuited or overloaded; when the fan stops rotating, check the fan power supply or replace the fan; for communication abnormalities, check the communication interface connections and network configuration; when the module fails, perform an online hot-swappable replacement operation, and after replacement, verify the output voltage and load operation status.

Replacement Considerations: Support online hot-swapping, so no shutdown is required during replacement; first disconnect the input switch of the faulty module, remove the wiring, then remove the module, install the new module, and restore the wiring, close the input switch, and confirm that the module starts normally and the output is stable; the old module should be stored according to specifications to avoid damage from static electricity and moisture.
