1. In order to prevent the occurrence of fire or electric shock, please place the UPS power supply in an indoor environment with appropriate temperature and humidity, and ensure that the environment is not polluted by non-conductive substances. In order to avoid overheating of the UPS power supply, do not shield or cover the ventilation holes of the UPS power supply, and avoid placing the product in a location directly exposed to the sun or near heating devices such as electric heaters or stoves.

　　2. Do not directly plug in non-computer related equipment, such as medical appliances, life-sustaining equipment, microwave ovens, or vacuum cleaners. Do not insert the plug of the UPS power supply into its own output socket. Absolutely avoid the inflow of liquid or foreign objects into the inside of the UPS power supply. Do not place beverages or any vessels containing liquids on or near the UPS power supply.

　　3. In an emergency, please press the shutdown button and unplug the power cord from the socket to properly shut down and isolate the UPS power supply. Do not plug the extension cord or protection socket into the UPS power supply. (Ordinary power strips can be used) If the UPS power supply adopts a metal shell, based on safety considerations, grounding must be implemented when installing the UPS power supply, so as to suppress the accidental leakage power below a safe 3.5mA.

　　 4. Beware of the risk of electric shock. Even if the plug of this product has been removed from the socket, the power contained in the internal battery is still dangerous. Therefore, when repairing the inside of the product, the positive and negative poles of the battery must be disconnected from the quick connector to ensure safety.

　　 5. When the internal battery is maintained or repaired, relevant professionals should perform or guide by the side, and take necessary measures. Unauthorized personnel are not allowed to approach the battery.

If the electrolyte contained in the battery leaks, it will cause damage to the skin and eyes. Before cleaning the UPS power supply, be sure to unplug the plug first, and do not smear or spray any liquid such as cleaning fluid.

　　 8. The battery has a risk of electric shock, and a dangerous high current will be generated when a short circuit occurs. Therefore, before replacing the battery, please observe the following:

　　 (1) Remove watches, rings, and any metal objects worn;

　　 (2) Use tools designed with insulated handles;

　　 (3) Put on rubber gloves and work shoes;

　　 (4) Do not place tools or metal parts on the battery;
