|
|
|
| |
| • | Low input voltage | • Check the DC connections and the | |

| (fault code E01) |
| cable. |
|
|
| • | Recharge the battery. |
|
|
|
| |
| • | High input voltage | • Verify the unit is connected to a 12V | |
|
| (fault code E02) |
| battery. |
|
|
| • Check the voltage regulation of the | |
|
|
|
| external charging system (if any). |
|
|
| ||
| • Unit overload or AC | • Reduce the load. Make sure the load | ||
