1. The use of lithium UPS should pay attention to the parameters of the UPS, such as the input voltage range, output waveform, output power, long power supply time, switching time, as well as lithium battery brand, machine noise, volume, weight and other parameters. All kinds of UPS should not work at full load, should retain more than 20% of the power margin, good load control in the UPS rated output power between 40% and 60%.
2. When the lithium battery UPS is not used for a long time, it should be switched on every once in a while. For backup UPS is recommended every 1 month, so that the UPS work in the inverter operating state at least 2 ~ 3 minutes, in order to activate the battery, to extend the service life of the battery. When charging, over-current and over-voltage charging should be avoided as much as possible. Proper discharge will help activate the battery.
3. Master the basic knowledge of lithium battery UPS, carefully read the equipment manual, to clarify the various warning messages, warning codes, the meaning of the indicator, as well as the reasons for the occurrence of and ways to deal with. Familiarize yourself with the role of various switches and buttons on the equipment. Familiarize yourself with the various operations of the UPS, and be clear about the connection relationship.
4. Strengthen the daily inspection, maintenance, check the equipment, there is no alarm, there is no smell, there is no abnormal sound, check the joints have no loose heat phenomenon, cooling fan operation is normal, the equipment of various instructions is normal, found that the problem is solved in a timely manner.
5. Maintain a suitable ambient temperature. The important factor affecting the life of lithium UPS battery is the ambient temperature, the general battery manufacturers require the best ambient temperature is between 20-25 ℃. Once the ambient temperature exceeds 25 ℃, every 10 ℃, the battery life will be shortened by half.
6. Timely replacement of waste / bad battery. In the continuous operation of lithium UPS use, due to performance and quality differences, individual battery performance decline, storage capacity to meet the requirements and damage is inevitable. When the battery pack in a / some batteries appear damaged, the maintenance staff should be checked on each battery test, to exclude damaged batteries.
7. Lithium UPS should be used in a well-ventilated environment, conducive to heat dissipation, and keep the environment clean. Do not take inductive loads, such as money counting machines, fluorescent lamps, air conditioning, etc., so as not to cause damage to the uninterruptible power supply bad.
8. Do not frequently turn off and on the lithium UPS power. Generally to turn off the UPS power supply 6 seconds before turning it on again, otherwise the UPS power supply may be in the "startup failure" state, that is, the UPS power supply is in the state of neither utility output, and no inverter output.
