Possible Causes
If the mains voltage (volts) is higher
than permitted, the converter is
disconnected. Seldom occurs.
Main voltage (volts) is too low for the
time being. May be due to lightning or
a loose contact in the cables. Could
occur if someone connected to the
mains is using a powerful welder.
Check the cables and connections.
Temperature too high in the
electronics. See E 08. May also
happen if the mains voltage is too
low and the power consumption is to
high, creating heat in the electronics.
Ventilate the cabinet and turn the
machine off for a while with the door
open.
One of the incoming phases is
missing. Check the fuses, cables and
connections.
Contact service. The converter must
be reset.
