VI. Installation and Maintenance

(1) Installation Requirements

Installation location: Installed on Ovation standard I/O rack DIN rail or 19-inch cabinet, installed firmly and vibration-proof; reserve ≥100mm of space above and below the module and ≥50mm 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-in or rack fasteners to ensure good contact between the module and the backplane; wear an anti-static wristband during installation to avoid damage to electronic components due to static electricity; when installing multiple modules in parallel, the spacing should be ≥50mm to ensure heat dissipation and signal isolation; when redundant installation is performed, the spacing between the two modules should be ≥100mm to facilitate maintenance and heat dissipation.

Cable connection specifications: Input side uses compliant AC power cables, connections are firm and without loosening, distinguish clearly between live, neutral, and ground wires; output side uses multi-strand copper core DC cables, positive and negative pole connections are correct, to avoid reverse polarity; all connection terminals should be tightened with a torque of 1.5–2.0N・m to prevent loosening and overheating; the cables should be neatly arranged, away from strong electromagnetic interference sources, and avoid excessive bending.

(2) Maintenance Points

Regular inspection: Monthly inspection of module appearance, LED status indicator light, operation status of cooling fans, and connection terminals, confirm normal input and output voltages, no overheating, abnormal noise, or loosening; check the DCS system diagnostic log to identify potential issues such as input abnormalities, output fluctuations, and fan failures. Cleaning and Maintenance: Every quarter, use a dry soft cloth or low-pressure compressed air to wipe the surface of the module, the cooling fan, and the ventilation opening. Remove dust and oil stains to prevent dust accumulation from affecting heat dissipation and insulation performance. In dusty environments, the cleaning cycle can be shortened to once a month. Do not use corrosive cleaning agents or liquids for direct wiping.

Troubleshooting: When the output is abnormal, first check if the input voltage is normal and if the wiring is loose, then check if the load is short-circuited or overloaded; when the fan stops rotating, check the fan power supply or replace the fan; when the module fails, perform an online hot-swapping replacement operation, and after replacement, verify the output voltage and the operating status of the load.

Replacement Notes: 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, 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.
