With the rapid development of information technology in small and medium-sized enterprises, the power supply system of units has become increasingly important, which is often referred to as the contribution of UPS. Therefore, it is also necessary for small and medium-sized enterprises to equip UPS to prevent data loss. UPS is the English abbreviation for uninterruptible power system, which is an important external device that can provide continuous, stable, and uninterrupted power supply. Below, we will share some common steps for installing UPS with some experience from Jinchi.
1、 Safety instructions
● Even if the UPS is not connected to the mains, its power output socket still has 220V voltage.
● In order to reduce the risk of electric shock caused by poor grounding of load equipment, the AC input power should be disconnected when installing the computer interface signal line. Only after connecting all signal connectors can the power be connected.
● Connecting the UPS to an AC input power supply with a ground wire must be equipped with an appropriate branch protector (circuit breaker). Connecting to any other type of socket may cause electric shock injury.
● If the charging or power cord needs to be replaced, please purchase raw materials from our company's service station or distributor to avoid heating or sparking due to insufficient capacity, which may cause a fire.
● Do not use fire to handle batteries or battery packs, as it may cause explosion and injury.
● Do not open or damage the battery, as the spilled electrolyte has strong toxicity and is harmful to human health.
● Please avoid short circuits between the positive and negative terminals of the battery, as this may cause electric shock or ignition.
● Do not open the UPS casing by yourself as 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 risk of high voltage between the battery terminal and the ground.
● It is not advisable to connect electrical equipment such as hair dryers and electric heaters to ensure the safety of the machine.
【Pay Attention To】
☆ There is high voltage inside the UPS. To avoid personal safety, please consult the dealer's professional personnel if you have any questions.
☆ Do not attempt to repair the UPS. The UPS does not contain any components that the user may maintain, and this UPS contains potential hazardous voltages. Repairs can only be carried out by qualified repair personnel who have been trained by the factory. If the user repairs or makes modifications themselves, the warranty qualification will be cancelled.
2、 Installation precautions
● The area where UPS is placed must have good ventilation, away from water, flammable gases, and corrosive agents.
● It should not be placed on the side, and the air inlet holes at the bottom of the front panel, the fan outlet holes on the rear cover plate, and the air inlet holes on the side of the box should be kept unobstructed.
● The ambient temperature around UPS should be maintained between 0 ℃ and 40 ℃.
● If the machine is disassembled and used at low temperatures, there may be condensation of water droplets. It is necessary to wait for the inside and outside of the machine to completely dry before installation and use, otherwise there is a risk of electric shock.
● Please place the UPS near the mains power input socket in order to unplug the mains power input plug and cut off the power in case of emergency.
【Pay Attention To】
☆ When connecting the load to the UPS, it is necessary to first turn off the load, then connect the wires, and then turn on the load one by one.
☆ Connect the UPS to a dedicated socket with overcurrent protection device.
☆ The power socket used should be connected to the protective ground terminal.
☆ Regardless of whether the input power cord is plugged into a mains outlet or not, the UPS output may be live, and turning off the UPS does not guarantee that the internal components are not live. If you want the UPS to have no output, you must first turn off the switch and then cancel the mains supply.
☆ When it is necessary to connect inductive loads such as electric motors, displays, laser printers, etc., due to their high starting power during operation, when selecting UPS, the capacity should be calculated based on the starting power. The starting power is generally taken as twice the rated power.
☆ If connected to the generator, the following steps need to be followed:
Start the generator, wait for its stable operation, and connect the output power of the generator to the UPS input terminal (at this time, ensure that the UPS is unloaded). Then, follow the startup program to start the UPS. After the UPS is started, connect the load one by one (it is recommended to choose the generator capacity based on twice the capacity of the UPS).
【Pay Attention To】
☆ Before replacing the battery, the UPS must be turned off and disconnected from the mains.
☆ Remove metal items such as rings and watches.
☆ Use a screwdriver with an insulated handle and do not place tools or other metal objects on the battery.
☆ When connecting the battery cable, it is normal for small sparks to appear at the connector and will not pose a threat to personal safety or UPS. Never short-circuit or reverse connect the positive and negative terminals of the battery.
