  If the icons are flashing on the LCD display and the alarm sounds twice every second, it means that your INFOSEC UPS is overloaded. You should remove excess loads from the UPS output. In some cases devices connected to the UPS are fed directly by the electrical network via the Bypass. After repetitive overloads, the UPS can be locked in the Bypass mode. To resolve this, remove excess loads from the UPS output first, then shut down the UPS and restart it.

  If fault code 14 is displayed, the icon lights up, and the alarm sounds continuously on your INFOSEC UPS, it indicates that the UPS shut down automatically because a short circuit occurred on the UPS output. Check the output wiring and if the connected devices are in short circuit status.
