Maintenance
8.4. Checking UPS State
We recommend checking the operational state of the UPS regularly.
Check the following items:
1. Check for any UPS fault conditions: Is the alarm indicator on? Are there any UPS alarms active?
2. Check if the UPS is operating in Bypass mode. Under normal conditions, the UPS operates in Normal mode;
if you find that it is operating in Bypass mode, determine the reason (operator intervention, overload, internal
fault, etc.)
3. Check if the battery is discharging: If the AC mains supply is within normal limits, the battery should not be
discharged; if you find that it is operating in Bypass mode, determine the reason (mains failure, battery test,
operator intervention, etc.).
8.5. Checking UPS Functions
• UPS functions check procedures may cause power interruption to load.

Backup the load data before conducting the UPS functional check. The procedures are as follows:
1. Press the power button to check if the buzzer beeps, the indicators are on and the LCD display is normal.
2. Press the ESC key and check again that the indicators are on, the LCD display is normal, and that the UPS
has been transferred to inverter mode.
