For an inverter with a floating output, you will need to provide a power supply via the supplied top-hat rail power sup-
ply unit. Install the power supply unit in a suitable switch cabinet or similar and then lay the cable at the installation
location. The allocation is shown in the following table.
The connection itself is described in
Step 8

Please note that the length of the cables between the power supply unit and the inverter or relay must not ex-
ceed 30 metres.
Screwing to the wall
Once the installation location has been prepared, you can screw the mounting plate to the wall.
Proceed as follows to prepare the 1W0001 and PVEMH10 mounting plates:
1
Loosen the control cable which is fixed to the back
of the 1W0001/PVEMH10 with a cable tie.
2
Run it through the opening to the front of the
mounting plate.
