According to the system configuration, check the correct setting of the channels to indepen-
dent or in parallel mode. An incorrect setting of the input channels can lead to loss of energy
production.
Polarity inversion can cause serious damage. Check polarity before connecting each string!
If any string inputs are not required, you must ensure that covers are installed to the connec-
tors, and install any which are missing.
This is necessary both for the inverter seal, and to avoid damage to the free connector which

may be used at a later time.
Connect all the strings required by the system, always checking the seal
of the connectors.
The figure below shows a connection example of the string inputs on a
TRIO-7.5/8.5 inverter (with dual input channel). Each input channel is
connected to a string, while the protective covers are installed to unused
connectors
