Fronius MagicWave 1700, Operating Instructions Manual

The digital power sources are equipped with an intelligent safety system. This means
that apart from the fuse for the coolant-pump, it has been possible to dispense with
melting-type fuses entirely. After a possible malfunction or error has been remedied, the
power source can be put back into normal operation again without any melting-type
fuses having to be changed.
Warning! An electric shock can be fatal. Before opening up the power source,
switch it off, unplug it from the mains and put up a clearly legible and easy-to-
understand warning sign to stop anybody inadvertently switching the machine
back on again. If necessary, discharge the electrolytic capacitors.
Troubleshooting
If any error message that is not described here appears on the displays, then the fault is
one that can only be put right by a service technician. Make a note of the error message
shown in the display, and of the serial number and configuration of the power source,
and get in touch with our after-sales service, giving them a detailed description of the
error.
