5 - Installation

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 

UNO-DM-3.3-TL-PLUS-SB inverter.

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.
