What to do if my Borri B400-020-B (C) is overloaded?
If your Borri UPS is overloaded, it means there is too much demand on it. The solution is to check the connected loads and remove any non-critical devices to reduce the load.
Why is the emergency supply period shorter than nominal value on my Borri B400-020-B (C) UPS?
If the emergency supply period of your Borri UPS is shorter than expected, it could be due to batteries not being fully charged or the batteries being defective. Try charging the batteries for at least 5-8 hours, and then check their capacity. If the issue continues, it is recommended to consult your dealer.
What to do if the battery LED lights up and the alarm sounds on my Borri B400-020-B (C) UPS?
If the BATTERY LED is lit and the Borri UPS is beeping once every 4 seconds, it indicates that the mains power supply has failed, or the input power and/or frequency are out of tolerance. The UPS is automatically switching to battery mode. You should check the input power source. If the problem persists, inform your dealer.
Why is the inverter temperature high on my Borri UPS?
If the inverter temperature is high on your Borri UPS, it means the internal temperature of the UPS is too high. Check the ventilation of the UPS and the ambient temperature of the room to ensure proper cooling.
Why is the DC-DC temperature high on my Borri B400-020-B (C) UPS?
If the DC-DC temperature is high in your Borri UPS, it indicates that the internal temperature of the UPS is too high. You should check the ventilation of the UPS and the ambient temperature to ensure it's adequately cooled.
What causes battery over voltage in Borri B400-020-B (C) UPS?
If there's a battery over voltage issue with your Borri UPS, it means the battery is being overcharged. The UPS will switch to battery mode automatically. After the battery voltage returns to normal and the mains power is stable, the UPS will switch back to Online mode automatically.
What does line voltage high (OVCD action) mean on my Borri B400-020-B (C) UPS?
If your Borri UPS indicates a high line voltage (OVCD action), it means the input power voltage is too high. The UPS will automatically switch to battery mode. Once the mains power returns to normal, the UPS will switch back to online mode automatically.
What to do if there is an inverter short in my Borri B400-020-B (C) UPS?
If there's an inverter short in your Borri UPS, it indicates an output short circuit. Remove all the loads, and turn off the UPS. Inspect the output of the UPS and the loads for any short circuits. Ensure the short circuit is resolved and that the UPS has no internal faults before turning it back on.
Why is the BYPASS LED on my Borri B400-020-B (C) lit when power is available?
If the BYPASS LED lights up on your Borri UPS even when the power supply is available, it means the inverter is not switched on. Press the On-Switch labeled “I” to activate the inverter.
What does it mean when my Borri B400-020-B (C) UPS beeps every second?
If your Borri UPS is beeping every second, it means the battery voltage is low and the battery is almost empty.
