Procedure
1. Open the inverter as described in section 7.2 "Opening the Inverter" (page 56).
2. Insert the cable into each inverter.
Use one of the two cable glands (F) on the bottom right hand side.
3. Draw the cable along the cable route (E) as far as the terminal block (B).
4. Ground the shield in each inverter at the PE terminal (D).
5. Sheath the positive and negative cable conductors in each inverter with wire sleeves.
6. Connect the positive and negative pole to the
corresponding screw terminals.
7. In order to connect the three inverters together, connect the positive and negative conductors
from the two other inverters to the terminal block of the middle inverter.
The cable length between two inverters may not exceed 300 m.
DANGER!
Danger to life through high voltage if there is a fault with the
SMA Power Balancer cable!
• Sheath the positive and negative cable conductors in each inverter using the
enclosed silicone tube.
• Cut the silicone tube to the required length.
• The silicone tube must completely cover the cable inside the inverter enclosure.
