5.2 Status LED overview
LED status indicators
The Control Unit has number of dual-colour LEDs which are designed to indicate the
operational state of the Inverter. The LEDs are used to indicate the status of the following
states:
● General fault conditions
● Communication status
● Input and Output status
● Safety-Integrated status
The location of the various LEDs on the Control Unit are shown in the figure below.
