NOTICE
Metal chips in the converter
Chips are created when cutting out the floor panel. Chips in the converter shorten
clearances and creepage distances and can lead to flashovers.
● Cut out the floor panel outside the area of the converter.
● Take care that no metal chips are left in the converter.
● Protect cut edges to prevent damage to the cable insulation.
