Start the UPS Using Mains Power
Procedure
- Switch on the external battery circuit breaker (if any).Switch on the external AC input circuit breaker Km for the UPS. The UPS will enter the bypass mode. Press and hold SELECT for 1s on a non-setting screen to access the login screen for parameter settings. The initial password is 000001. Enter the correct password to access the UPS setting mode.Figure 5-2 Password input screenFigure 5-3 Bypass mode
- Set the output voltage based on site requirements.
Output Voltage
Description
You need to shut down the inverter before changing the output voltage.
220: indicates that the output voltage is 220 V AC.
230: indicates that the output voltage is 230 V AC (default value).
240: indicates that the output voltage is 240 V AC.
- Set the battery capacity.
Battery Capacity
Description
- Default value: 100 Ah
- Value range: 50–2400 Ah. The value increases by 50 Ah each time you press SELECT.
- Press and hold ON/MUTE for more than 5s. Release the button when you hear a beep sound. The UPS starts to work in normal mode.Figure 5-4 Normal mode
