Procedure
1. Open the inverter as described in Section 7.2 "Opening the Inverter" (page 57).
2. Insert the cable into each inverter.
Use one of the two enclosure openings (F) on the bottom right hand side.
3. Lead the cable along the cable route (E) as far as the terminal block (B).
4. Ground the cable shield in each inverter at the PE terminal (D).
5. Sheath the positive and negative cable conductors in each inverter with end sleeves.
6. Connect the positive and negative pole to the
corresponding screw terminals.
7. To connect the 3 inverters, connect the positive and negative cables from the 2 other inverters
to the terminal block of the middle inverter.
The length of the cables between 2 inverters must not exceed 300 m.
DANGER!
Danger to life due to high voltages on the SMA Power Balancer cable when
faults occur
• Sheath the positive and negative cable conductors in each inverter using the silicone
tube provided.
• Cut the silicone tube to the required length.
• The silicone tube must completely protect the cable inside the inverter.
