Fault tracing

This chapter describes the fault tracing of the inverter.

LEDs

The table identifies the location, name, color and meaning of the LED indicators in the 

inverter.

Where

LED

Color

Indication

Inverter main status 

panel (outer control 

cabinet door)

Operating

Green

The inverter operates normally.

Warning
