General The power sources are equipped with an intelligent safety system, meaning it has
been possible to dispense with nearly all fuses. After a possible malfunction has
been remedied, the power source can be used again as normal.
Possible malfunctions, warning notices or status codes are shown on the display
as plain text dialogues.
