Troubleshooting via the Mimic Diagram LEDs

The mimic diagram shows the status of the main functions and the energy flow supplying the load. The different LEDs are either green, red or turned off depending on the status of the system functions. In this section it is listed what a red LED on the mimic diagram is indicating to help troubleshooting.

Input LED

If the input LED is red, it can be caused by the following:

• UIB is open

• Input out of tolerance (waveform-, voltage-, or frequency out of tolerance)

Inverter LED

If the inverter LED is red, it can be caused by the following:

• Inverter inoperable

Load LED

If the load LED is red, it can be caused by the following:

• UOB is open

• SIB is open

• Output voltage out of tolerance

Battery LED

If the Battery LED is red, it can be caused by the following:

• Critical battery alarm active

• Charger inoperable

• Battery breaker disconnected
