This article mainly introduces the UPS uninterruptible power supply safety instructions, installation notes and maintenance.

1. Safety Instructions

● Even if the UPS is not connected to the mains, its power outlet still has 220V.

● In order to reduce the risk of electric shock caused by poor grounding of the load equipment, the AC input power should be disconnected when installing the computer interface signal cable, and the power supply can only be connected after all signal connectors are connected.

● When connecting the UPS to the AC input power supply with a ground wire, it must be equipped with an appropriate branch protector (circuit breaker), which may cause electric shock injury if it is connected to any other type of socket.

● If the charging cable or power cord needs to be replaced, please purchase raw materials from our service station or distributor to avoid heat or fire due to insufficient capacity, causing fire.

● Do not dispose of the battery or battery pack with fire, otherwise it will explode and injure people.

● Do not open or damage the battery. The spilled electrolyte is highly toxic and harmful to humans.

● Please avoid short circuit of the battery's positive and negative poles, otherwise it may cause electric shock or fire.

● Do not open the UPS case by yourself, there is a risk of electric shock.

● Do not touch the battery connection terminals. The battery circuit is not isolated from the input voltage circuit, and there is a danger of high voltage between the battery terminals and ground.

● Electrical equipment such as hair dryers and electric heaters should not be connected to ensure the safety of the machine.

Two [Notes]

☆ There is high voltage in the UPS, in order to avoid injury to personal safety, if you have any questions, please consult dealer professionals.

☆ Do not try to repair the UPS. The UPS does not contain any parts that the user may maintain and this UPS contains potentially dangerous voltages. Repairs can only be performed by qualified maintenance personnel trained by the factory. Repairs or modifications by the user will cancel the warranty. qualifications.

2. Installation considerations

● The area where the UPS is placed must be well ventilated, away from water, combustible gases and corrosives.

● It is not suitable for measuring and placing, and the air inlet hole at the lower end of the front panel should be kept unobstructed: the air outlet hole of the rear cover fan and the air inlet hole on the side of the cabinet

● The ambient temperature around the UPS should be maintained between 0 ℃ -40 ℃.

● If the machine is disassembled and used at a low temperature, water droplets may condense. You must wait for the inside and outside of the machine to be completely dry before installing and using, otherwise there is a risk of electric shock.

● Please place the UPS near the mains input socket, so as to unplug the mains input plug and cut off the power supply in an emergency.

【note】

☆ When the load is connected to the UPS, you must first turn off the load, then connect the wire, and then turn on the load one by one.

☆ Connect the UPS to the special socket with overcurrent protection device.

☆ The power socket used should be connected to the protective ground.

☆ No matter whether the input power cord is plugged into the mains socket, the UPS output may be live. Turning off the UPS does not guarantee that the internal parts of the machine are not live. If you want to make the UPS no output, you must first turn off the switch, and then cancel the mains supply.

☆ When inductive loads such as motors, monitors, and laser printers need to be connected, the starting power is too large. When selecting a UPS, the capacity should be calculated based on the starting power. The starting power is generally twice the rated power.

☆ If the generator is connected, follow the steps below:

Start the generator, and after the operation is stable, connect the generator's actual output power to the UPS and the input terminal (at this time, make sure that the UPS is empty), and then start the UPS according to the startup procedure. After the UPS is started, connect the load one by one (recommended Select the generator capacity with twice the capacity of the UPS).

Never short-circuit or reverse-connect the positive and negative poles of the battery
