DANGER!
Danger to life due to high voltages in the inverter!
• Open the inverter as described in its installation guide.
2. Remove both varistors.
For this purpose, use the extractor tool provided. As
an alternative, however, the terminal contacts can
be operated individually using a suitable
screwdriver.
3. Peel the delivered labels for the respective inverter type slowly from the label sheet. Check that
the label material is removed from the perforated holes.
4. Attach the label to the varistor terminal block. The
rectangular holes in the label must be placed over
the rectangular openings in the varistor terminal
block.
5. Fold down the overlapping flaps and press firmly at
the sides.
Positioning of the Label
A reverse polarity protected connection of the grounding set and secure functioning can
only be guaranteed if the relevant varistor label is positioned correctly.
