6. Installation & Maintenance

Installation Guidelines

• Environmental Requirements: The installation location should be dry and well-ventilated, avoiding direct sunlight or strong magnetic field interference. The anti-corrosion model (EOD-F) is suitable for humid or corrosive environments
• Wiring Specifications: Strictly wire according to the voltage and current specifications on the nameplate. Input and output terminals should use appropriate junction boxes or terminal blocks
• Heat Dissipation Space: Ensure sufficient heat dissipation space around the equipment (usually requiring a gap of more than 6 inches) and avoid blocking ventilation openings
• Ground Protection: Ensure good grounding of the equipment to prevent electrical noise and leakage current

Maintenance Points

• Regular Inspection: Regularly check the tightness of power cables and terminal connections to prevent malfunctions caused by loosening
• Clean Heat Sink: Remove dust from heat sinks and fan blades to ensure heat dissipation effect
• Software Update: Regularly check the drive firmware version and upgrade if necessary to fix bugs or improve performance
• Spare Parts Management: It is recommended to equip common spare parts (such as fans, wiring terminals) for quick replacement
• Troubleshooting: Quickly locate problems through error codes displayed on the panel or by reading fault logs via upper computer software
