Was bedeutet SP0030 ?

An overcurrent condition is detected in the input circuit of the converter unit. This indicates excessive current draw from the main power supply or a fault in the input stage.

• Input power supply to the converter unit is unstable or too low.
• Short circuit in the converter's input rectifier stage.
• Faulty input filtering components (e.g., chokes, capacitors).
• External electrical noise affecting input current.
