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.

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 correctly attached with the
correct torque (see Section 5.4, page 43).

Protection class of PV modules
The inverter must only be operated with PV modules of
protection class II, compliant with IEC 61730, application
class A.
Only connect PV modules to the inverter. Other energy
sources are not allowed.
PV modules generate a voltage when exposed to light.
