equipment have a large starting current, and overload protection action (or bypass action) may occur during startup. At this time, it is best to start such equipment before other equipment. 10 Use 10.1 Precautions for use 1) Before starting the inverter, pay attention to check whether the load is appropriate. The user's load shall not exceed the rated power of the inverter, otherwise the inverter will be in overload protection or bypass power supply all the time. 2) During startup, the inverter must meet the following conditions: ① Snap switch: the switch must be in lock state, otherwise it cannot be started; ② LCD display screen:
the working status of each module can be queried through the display screen; ③ Key: " on/off" key is used for UPS cold start or shutdown. When it is necessary to turn on/off, press and hold this key for about one second until the welcome interface appears on the LCD screen or UPS shutdown information is displayed; Note: gently press the "page turning" key to view the operation status of each ups on the LCD display screen. 3) The power switch of load equipment can be turned on only after the inverter starts and enters stable operation. 10.2 Preparation before startup The load capacity of inverter is designed according to 70% (nominal rated power) resistive load.
It is recommended that the load capacity not exceed the inverter output capacity (VA). In order to make the inverter work normally, please confirm the following items before startup: 1) The installation check of input and output is correct. 2) The input power terminal is connected to the rated input power. 3) Confirm that the inverter output has no short circuit and the load capacity cannot exceed the inverter capacity. 10.3 operation After the correct installation is completed, just press and hold the on/off key for about one second until the LCD display shows "testing, please wait", indicating that the machine is started 20
