What does Warn: End of discharge mean on my OPTI-UPS DS-I?
This warning on your OPTI-UPS UPS means that it has been working in battery mode for an extended period following a utility failure. Save your data when the UPS alarms “utility fail”.
How to fix OPTI-UPS UPS Output CT fault?
If your OPTI-UPS UPS shows an Output CT fault, check if the output CT has been assembled mistakenly. Assemble the output CT as per the device package on the PCB.
What does Warn: Input voltage abnormal mean on my OPTI-UPS DS-I UPS?
If your OPTI-UPS UPS displays 'Warn: Input voltage abnormal', it means that the utility power has failed or the input surge protector has opened. If the utility is normal but the rectifier is not working, reset the input surge protector.
What does Warn: Battery test failure mean on my OPTI-UPS DS-I?
This warning on your OPTI-UPS UPS indicates that the battery capacity is low, or the load is low. Ensure that the battery voltage is higher than 36VDC and the load is more than 30%.
What does Warn: Line neutral wires reversed/PE not grounded mean on my OPTI-UPS DS-I?
This warning on your OPTI-UPS UPS indicates a problem with the wiring. It could mean either: 1. The input line and neutral wires are reversed: Check the polarity of the line wire and neutral wire. 2. The PE wire is not correctly connected in the UPS: Check if PE on the input plug is shorted with the UPS rear panel. If yes, please check PE wire in the input power socket.
How to activate EPO on OPTI-UPS DS-I UPS?
To activate EPO (Emergency Power Off) on your OPTI-UPS UPS, short the EPO terminal 1&2.
How to fix OPTI-UPS DS-I battery not connected?
If your OPTI-UPS UPS indicates that the battery is not connected, check if the battery switch is off or if the battery cables are disconnected.
Why does my OPTI-UPS DS-I say Fault: Battery low?
The OPTI-UPS UPS indicates this fault because it is running on battery, and the battery voltage is low. Recover input power or save data upon “battery low”.
What does Warn: Bypass voltage abnormal mean on my OPTI-UPS DS-I UPS?
This warning on your OPTI-UPS UPS means that the bypass voltage is either out of the bypass range or is off. Check if utility power is indeed out of range.
Why does my OPTI-UPS DS-I say Warn: Bypass overload?
The OPTI-UPS UPS is indicating a bypass overload because the load is on bypass and is exceeding capacity. To resolve this, remove some loads to ensure that the total load is less than 95% of the rated capacity.
