4.1.2.2 LED Indicators

The mimic diagram serves to indicate the general status of the UPS. The LED-indicators show the power flow
status and in the event of mains failure or load transfer from inverter to bypass and vice-versa. The
corresponding LED-indicators will change colours from green (normal) to red (warning).
The LED's LINE 1 (rectifier) and LINE 2 (bypass) indicate the availability of the mains power supply.
The LED's INVERTER and BYPASS if green indicate which of the two is supplying power to the critical load.
When the battery is supplying the load due to mains failure the LED-indicator BATTERY is flashing.
The LED-indicator ALARM is a visual indication of any internal or external alarm condition. At the same time an
audible alarm will be activated.
