1. Switch the PV load-break switch on the inverter to "Off"
and, if available, also on the PV array junction box.
2. Connect the PV cables from the PV array junction box
to the inverter. Ensure the correct polarity when doing
so.
3. All conductors must be properly attached with the
correct tool (screwdriver bit, length min. 50 mm) and
correct torque, see Section 5.4, page 45.

INFORMATION
Cables with multi-strand, fine-strand or extra
fine-strand conductors can be used for AC
connection (see figure 2.23). The cables must be
suitable for a temperature of at least 75°C.
When using fine-strand or extra fine-strand
conductors, bootlace ferrules must be used for the
connection.
