It is exttremely dang gerous and may m cause e electric shock k. ・Do nott insert finge ers or any metallic m elem ment through the protec ctive coverss. There is a risk of injjury and elec ctric shock.

W WARN NING ・When a MAJOR FA AULT occurrs, do not atttempt to res start the equipment you urself Contacct our custom mer service support. s ・Stop th he equipment immediattely when a malfunction n, abnormall noise and/o /or smell is observed. o Contacct our custom mer service support. s ・Do nott place objec cts over the e equipmentt Obstruccting the air exhaust ma ay cause tem mperature ris se in the inte erior of the innverter. Addiitionally, obje ects

!

may falll into the inte erior of the in nverter. ・In case e a fault occ curs, check and record fault condittions, panel display, fau ult contents s, and reporrt to our customer serv vice. Do not perform reco overy actions yourself. T There is a risk k of electric shock s and/orr injury. ・Before e connecting g to the ph hotovoltaic s source circuit and the grid, confiirm safety conditions c a and operatte the inverter carefully by followin ng the instru uctions given in this maanual. Improp per connectio on may cause e electric sho ock and acciidents. ・In case e the ground d fault alarm m is activate ed, stop the inverter and check for leakage current in the DC side circuit and wiiring There is a potentiall risk of electtric shock.

・ Do nott run the equipment witth the enclo osure doors open. There is a risk of ellectric shock k fire caused by the intrus sion of foreign objects. ・Do nott insert poin nted objects or fingers iinto the air intake/exhau i ust There is a potential risk of electtric shock. M Moreover, the ere is a risk of o injury from the rotating fan.
