CAUTION
PV installation
Unused PV inputs may not be short-circuited.
Illustration 2.22 DC Connection Area
1. On the inverter turn the PV load switch into off
position.
2. Connect the PV cables using Sunclix connectors.
Ensure correct polarity, see Illustration 2.21.
• Attach Sunclix mating part to PV cable.
• Connect to each PV input in the PV
connection area with a 'click'.

2.10.1 Protection Rating for PV Modules
The inverter must only be operated with PV modules of
protection class II, compliant to IEC 61730, application class
A.
Module voltage rating must be more than 480 V (typical
module voltage rating is 1000 V). This does not prevent
the use of strings with lower operating voltage.
Only connect PV modules to the inverter. Other energy
sources are not allowed.
