What to do if INVT HT1103L shows bypass overload timeout?
If the INVT UPS is on bypass and overloaded, and the overload time exceeds the bypass overload capacity, the UPS will shut down the output, causing a power loss to the loads. To resolve this, remove some loads, restart the UPS, and then turn on the loads one by one while the UPS is working normally.
Why does my INVT UPS show input voltage abnormal?
If your INVT UPS indicates an abnormal input voltage, it could be due to a utility failure. Alternatively, the input surge protector might have opened. If the utility is normal but the rectifier isn't working, try resetting the input surge protector.
How to fix INVT HT1103L bypass overload warning?
If your INVT UPS displays a 'Bypass Overload' warning, it means the load on the bypass is exceeding its capacity. To fix this, remove some loads to ensure the total load is less than 95% of the rated capacity.
What to do if INVT UPS warns about reversed line neutral wires or PE not grounded?
If your INVT UPS shows 'Line neutral wires reversed/PE not grounded', first check the polarity of the line and neutral wires. If that's not the issue, check if the PE on the input plug is shorted with the UPS rear panel. If it is not, contact your distributor or service center. If it is, check the PE wire in the input power socket.
How to troubleshoot INVT HT1103L 'Battery not connected' warning?
If your INVT UPS is warning that the battery is not connected, check if the battery switch is off or if the battery cables are disconnected.
