4.2 ePRO Combi LED Indicators and Error Modes

Please see the next image for an overview of all LED indicators on the 

ePRO Combi frontpanel, as well as the location of the main switch.

The frontpanel can be divided into four sections :

1.  Dual function level bar. Indicates the percentage of delivered output 

power  in  inverter  mode  (turns  red  if  more  than  nominal  output 

power is being delivered to the load). In charger mode, this level bar 

indicates the percentage of delivered charging current.

2.  Mode indicators. Indicate the operating mode of the ePRO Combi, 

as well as the status of each di
