4�4�1 External shutdown
This interface can be used to connect the inverter to an external grid monitoring system
which disconnects the inverter from the mains grid when this is needed.
While the external grid monitoring signal (the phase voltage) is connected to the "NA"
contact, the inverter feeds into the grid. When the signal stops, the grid relays of the
inverter are opened. This immediately disconnects the inverter from the grid.
The interface is configured with the free MaxTalk 2 Pro service software.

Procedure
1. Open the inverter as described in the instruction manual.
WARNING!
Fatal electric shock hazard!
Cables conducting mains voltage must be covered by the contact protection
inside the inverter.
■ ■
Always route the connecting cable through the middle cable gland
(Figure 5/Pos. 2).
2. Connect the wires as follows:
– Wire stripping length: 7 mm
Contact Description
NA Control line
N Neutral conductor
3. Close the unused holes in the cable gland using the locking pins.
4. Tighten the cable gland (wrench size: 34 mm).
5. Check the cable strain relief.
6. Close the inverter by
– engaging the contact protection;
– then tighten the cover.
You can now switch the inverter on as described in the instruction manual.
