Precautions For Using High-Power Aluminum-Cased Chargers

Using high-power aluminum-cased chargers requires strict control over multiple dimensions, including environment, operation, and maintenance, to ensure safe, stable, and efficient operation, extend service life, and avoid potential risks.

 

Ensure a Safe Charging Environment

Good Ventilation: Heat is generated during charging. It is essential to use the charger in a well-ventilated, dry environment free of flammable materials. Avoid enclosed spaces where heat buildup can lead to overheating.

 

Avoid Extreme Temperatures and Humidities: The recommended operating temperature is -20℃ to +45℃, and relative humidity is 5% to 95%. Exceeding these ranges may affect heat dissipation efficiency and electrical insulation performance.

 

Dust and Water Protection: Even with an IP67 protection rating, direct water exposure or prolonged exposure to high-dust environments should be avoided. Regularly check the sealing structure for damage.

 

Connect the battery first, then power on: When connecting, first connect the output terminal to the battery, confirming the positive and negative terminals are correct (reverse connection is strictly prohibited), then connect the AC power supply; the order is reversed when disconnecting the power to prevent instantaneous current surges.

 

Avoid plugging and unplugging under load: Do not arbitrarily plug or unplug the charging interface during charging to avoid arcing or electric shock hazards.

 

Monitor initial status: After turning on the power, observe whether the indicator lights and voltage/current displays are normal, and confirm that there are no abnormal phenomena such as smoke, unusual noises, or overheating.
