No user serviceable parts are contained in the inverter section.
Do not attempt to open or repair the inverter. The inverter section
is factory sealed to maintain its NEMA 4 rating and opening the top
cover of the power head will void the inverter warranty.

l’onduleur est scellée en usine an qu’elle conserve son courant
nominal NEMA 4, son ouverture annulerait la garantie.
