Troubleshooting
General
The devices are equipped with an intelligent safety system. This means that to a large ex-
tent it has been possible to dispense with melting-type fuses. Melting-type fuses therefore
no longer need to be replaced. After a possible malfunction has been remedied, the device
is ready for use again.
Safety
WARNING!
Work that is carried out incorrectly can cause serious injury or damage.
The following activities must only be carried out by trained and qualified personnel. Read
the safety rules in the wire-feed unit operating instructions.
WARNING!
An electric shock can be fatal.
Before opening the unit
► Turn the mains switch to the "O" position
► Unplug the device from the mains
► Put up an easy-to-understand warning sign to stop anybody inadvertently switching it
back on again
► Using a suitable measuring device, check to make sure that electrically charged com-
ponents (e.g. capacitors) have discharged
CAUTION!
Inadequate PE conductor connections can cause serious injury and damage.
The housing screws provide a suitable PE conductor connection for earthing (grounding)
the housing and must NOT be replaced by any other screws which do not provide a reliable
PE conductor connection.
