When using the UPS power supply, you should strictly abide by the relevant rules of the manufacturer's product specification to ensure that the front and the neutral line of the UPS connected to the mains meet the requirements. The primary purpose of equipping UPS is to prevent the computer from throwing away information and damaging the hard disk due to accidental power failure, but some equipment is not afraid of accidental power failure during operation.
In order to save the power of UPS, the printer can directly connect to the mains without going through the UPS. Assuming a network system, you can think about UPS only supplying power to the host (perhaps performance device) and some related things. This can ensure that UPS can be used in the most important equipment but also save money.
Do not overload the UPS. The maximum load of the UPS power supply should be 80% of its nominal load. Assuming overloaded operation, under inverter conditions, it often constitutes the breakdown of the inverter transistor. In addition, when using UPS, it is necessary to prevent the connection of rational loads such as fluorescent lamps, and only connect pure electricity or smaller capacitive loads.
You should pay attention to the sequence of power-on and power-off when turning on and off: turn on the UPS first when turning on the machine, and then register the power switch of the load later, and the power switch of the load must be registered one by one: when shutting down, the sequence is just the opposite, turn off the loads one by one Power switch, then turn off the UPS. UPS needs to be turned on for a long time, and the load such as the accounting machine is turned on whenever it is not necessary. After use, only the power switch of the load such as the accounting machine can be turned off.
Generally, it is required that after closing the UPS power supply, wait at least 6 seconds before turning on the UPS power supply. Otherwise, the UPS power supply may be in a state of "advocating failure", that is, the UPS power supply is in a state of no mains output and no inverter. The output is abnormal.
The electric energy in the battery in the UPS may be exhausted or nearly exhausted due to some factors. In order to compensate for battery energy and battery life, UPS must carry out timely and long-term successive charging to prevent shortcomings caused by battery failure.
UPSs newly purchased or stored for a long time should be charged for 12 hours before use. For UPS that is not stored for a long time, charge it for 12 hours every 3 months. If it is in a high-temperature area, charge it every 2 months. Use the UPS without charging, which will damage the battery.
