Usage Notes / Installation Tips

• Confirm the required input version — 120–130V AC or 170–250V AC — before ordering and installation.
• Confirm whether the connected equipment requires 12V DC or 24V DC.
• Do not exceed the rated wattage or current capacity of the selected model.
• For continuous operation, keeping the connected load at or below approximately 80% of rated power is recommended.
• Maintain adequate ventilation around the built-in cooling fan during high-power operation.
• Disconnect AC power before installation, maintenance, or wiring adjustments.
• Confirm DC output polarity and screw-terminal connections before powering connected equipment.
