What to do if Keatec Energy DBL MX-U inverter is out of order?
If the inverter is out of order, check and verify the AC input connections. Also, check and verify the Bypass connections Load (RED) Line (BLACK) and reconnect all AC connections. Make sure that the load does not exceed the rated output of the UPS and that the input voltage is within the range of
What to do if Keatec Energy DBL MX-U UPS shows inverter short circuit?
If the UPS indicates an inverter short circuit, check and verify the AC connections, ensuring that the Red wire is connected to the Load and the Black wire to the Line. Also, check the load for any short circuits. If the UPS is set to not retry, it will lock directly and show an error code and alarm. Clear the short and restart the UPS.
What to do if Keatec Energy UPS battery is weak or dead?
If the UPS indicates a weak or dead battery, check and verify the battery quantity, ensuring it does not exceed the maximum of 6 x 55AH without external ABM. Consider the age of the batteries and whether there has been a recent power failure. If the battery voltage measured during self-test is below 8nV (or 4mS) or 10.4nV (128ms), or if the battery voltage drops to 8nV suddenly, or if the battery voltage is lower than 12.5nV, the UPS will cease the self-test and show an error. For faster recharge, consider installing ABM.
What to do if Keatec Energy DBL MX-U UPS shows DC BUSS abnormal high-voltage-level?
If the UPS shows a DC BUSS abnormal high-voltage-level, remove all DC and AC connections. Connect the batteries, perform a DC Cold-Start, and when the UPS is operating, apply AC by connecting the AC harness.
