Notes on sending back
Send defective thyristor electronics to the manufacturer for repair. Please observe the following:
● Use suitable containers made of cardboard, wood or plastic for shipping.
● Use filler material to hold the thyristor electronics in place.
● Enclose dehumidification material if the packaging is air-tight.
● Note the ESD in the "Safety instructions" section.
NOTICE
Material damage due to inadequate packaging
Components can be bent by careless packing or insufficient packaging. This makes
determining the exact cause of the error difficult.
● When packing the thyristor electronics, take care not to bend protruding parts.
Note
Any information about the damage to the thyristor electronics will be helpful for determining the
cause of the fault and for repair. Moreover, this data is evaluated for a reliability analysis.
Include information about the most recent operational performance and about any previous
conspicuous behavior.
