Installation Manual SMC46-60A11-IA-en-81 39
Procedure
1. Open the inverter as described in Section 7.2 "Opening the Inverter" (page 48).
2. Insert the cables into each inverter.
Use one of the two enclosure openings (F) on the right-hand side.
3. Lead the cable along the cable route (E) as far as the terminal block (B).
4. Earth the cable shield in each inverter at the PE terminal (D).
5. Sheath the positive and negative cable conductors in each inverter using bootlace ferrules.
6. Connect the positive and negative poles to the
corresponding screw terminals.
7. In order to link the three inverters, connect the positive and negative conductors from the two
other inverters to the terminal block of the middle inverter.
The cable length between 2 inverters may not exceed 300 m.
D Flat male tab for earthing the cable shield
E Silicone tube/cable route
F Cable glands
