Installation Guide

CAUTION!
Ensure that the Plus (+) wire is connected to the + terminal and that the Minus
(-) wire is connected to the Minus (-) terminal connector.
 ATTENTION!

Veillez à ce que le câble Plus (+) soit connecté au terminal + et que le câble -
soit connecté au connecteur terminal.
NOTE
For systems with four PV strings per unit or more, fuses
may need to be installed in both the positive and negative
conductors as required by NEC Article 690.9. For more
information, refer to the “String Fusing Requirements
in SolarEdge Systems” technical note at
http://www.solaredge.com/files/pdfs/string_fusing_requirements.pdf.
NOTE
SolarEdge's fixed input voltage architecture enables the parallel strings to be of
different lengths. Therefore, they do not need to have the same number of
power optimizers, as long as the length of each string is within the permitted
range.
