Please note that it is imperative to avoid tensile force on the connection cables.
Please note that only the manufacturer’s connectors may be connected. Even
“compatible” connectors can loosen the connection and cause an electric arc. This is
especially important to consider when using power optimizers!
Any change in the connector socket can lead to the warranty being rendered null and
void, and therefore may only be carried out by trained and skilled personnel.
No damaged modules may be installed!
Both external connector sockets are fitted with a cable (1150 mm in length) and connectors. The socket (+) is located
on the right-hand side, and the plug on the left-hand side (-). (Figure 4) The connectors are each designed in such a
way as not to create confusion.
