注意事项 PRECAUTIONS

1 Input voltage: Ensure AC input is within the 85-264V range to avoid damage; use the recommended fuse (NAC-08-2A)

2 Operating temperature: 0-70°C, with output power derating required for operation above 50°C (follow derating guidelines)

3 Mounting: Use specified mounting holes and apply a maximum torque of 1.5N·m (for LEA150F model) to secure the unit

4 Connector current limits: Do not exceed 5A per pin for the CN2 connector to prevent overheating

5 ESD protection: Handle the unit with anti-static precautions (e.g., wristband) to avoid damaging sensitive electronic components

6 Modification: Do not disassemble or modify the power supply; unauthorized changes may void certifications and cause safety hazards

7 Isolation check: Perform an isolation resistance test before first use to confirm no insulation failure

8 Storage: Store in a dry environment with temperature between -20 to 85°C, free from condensation and dust

9 Remote control: When using remote ON/OFF (option S), ensure the control signal voltage is within the specified range (refer to the user manual)

10 Voltage adjustment: When using the potentiometer (option Y), limit output voltage adjustments to ±10% of the nominal value to maintain stability
