1. Charging Requires Skill
After purchasing the new portable UPS power supply, it should be plugged into the 220V power grid and charged for at least 12 hours to ensure the battery is fully charged. If the UPS is not used for an extended period, it should be turned on for 24 hours every 2 to 3 months to recharge, and allow the UPS power supply to operate in inverter mode for 2 to 3 minutes to ensure the battery's normal service life. Once the UPS power supply is turned on, the battery pack will begin charging. Press the power button for more than 1 second to activate the inverter.
2. Select a Reasonable Installation Location
Proper installation location is crucial. The placement of portable UPS units must ensure good ventilation. Keep them away from water, flammable gases, and corrosive substances. The environmental temperature should be between 0 and 40°C. Maintain clear air intakes and exhausts.
3. Install portable UPS
Please note the correct sequence of the neutral (N), live (L), and ground (G) wires, with particular attention to the ground wire. Do not connect the ground wire to a portable UPS if a ground fault occurs in the system.
4. Ensure safe operation for staff
When connecting the output power to a portable UPS, safety measures should also be taken. Due to the relatively high output voltage and current of portable UPS units, it is crucial to be cautious during the connection of the output power to prevent electric shock accidents.

5. Power-On and Power-Off Sequence When Using a Portable UPS
The correct power-on and shutdown sequence is to first turn on the UPS to supply power, followed by turning on various loads to avoid damage caused by transient current surges during the startup of the portable UPS. When shutting down, you should first turn off the loads and then shut down the UPS.
Avoid Overloading Portable UPS Systems
When using a portable UPS, calculate the load size. To avoid overloading or underloading, overloading can cause the UPS to remain in an overloaded state for extended periods, thereby reducing the lifespan of the portable UPS. If the load is too small, the UPS's working circuit stays in an abnormal state for prolonged periods, which is also harmful to the UPS. The load should be maintained between 50% and 80% for optimal performance.
7. Portable UPS Systems Should Not Be Left Idle for Extended Periods
For portable UPS units that have not been used for an extended period, please allow the UPS to be charged by the machine's charging circuit for 12 hours before restarting. For backup UPS units, it is advisable to reverse the operation of the portable UPS every month. Operate the transformer for 2 to 3 minutes to activate the battery.
8. Operations and Maintenance
During operation, strictly adhere to the relevant electrical operation procedures. In daily use, manage all power outlets on the UPS load side rigorously; it's preferable to differentiate them from the power outlets using color coding or other effective methods. Unused UPS outlets should be turned off or disconnected. It is strictly prohibited to connect electrical equipment unrelated to the UPS outlets, especially high-power tools.
