How to fix a Tecnoware ERA PLUS 900 that does not turn on?
If your Tecnoware UPS doesn't turn on, first, ensure the ON/OFF button is fully pressed. If it still fails to power up, the batteries might be flat. Recharge them for at least 4 hours. If neither of these steps works, the electronic board may have failed.
Why is my Tecnoware UPS always on battery mode?
If your Tecnoware UPS is always functioning on battery mode, check that the input mains power cable is correctly connected and that there is electrical power. Also, inspect the input mains fuse; if it's burnt, replace it with one of the same type. The UPS may be running on battery due to black-out conditions, surge, over-voltage, or low-voltage; in this case, wait until the AC input line returns to normal. If none of these are the cause, the electronic board may have failed.
What to do if Tecnoware UPS battery life is too short?
If the battery autonomy of your Tecnoware UPS is too short, the battery may not be fully charged. Recharge it for at least 6 hours. If the problem persists, the electronic board may have failed.
