1. Install the TS4 module-level power electronics
(MLPE) on the back of the PV modules.
2. Connect the PV module to the TS4 input
conductors.
3. Connect the TS4 output conductors together to
form a string.
4. If using the TS4-A-F/TS4-A-2F, no additional steps
are necessary.
5. Remove each barcode sticker from the TS4-A-O
and place in the grid on the last page of this
document in the position and orientation of the
module as it is in the array. If using the TS4-A-F/
TS4-A-2F, this step is not necessary.
CAUTION - To prevent damage to the TS4, always connect PV modules to the TS4 input before connecting output
conductors in the string. Refer to the TS4 Installation Manuals for the TS4 installation requirements.
3.1.4 Connect PV Array
1. Run the PV wires through the strain relief into the EI
Link.
2. Strip 12 mm off wire ends and crimp them with the
provided 6mm2ferrules.
3. Press the wires into the appropriate PV + and PV -
terminals (Refer to the wiring diagram at the back of
the EI Link door.
