The inveerter installationn must be in fu ull compliance with local safeety standards an nd regulatioons, avoid closee to flammablee or explosive mediums, so as to avoid firre accident.. Only afteer obtaining thhe approval of the t local nationnal laws and reegulations of th he administrrative department, that invertter can be connnected to the power grid, an nd must be ooperated by quaalified personneel. Before coonnecting solarr panels and inv verter, the panells surface mustt be covered witth opaque oobjects, ensurinng the connectiion cables are not dangerous due to the hig gh voltage. Please fu fully understannd the installattion manual o f Litto photov voltaic grid tieed inverter bbefore installatiion and wiring. The inveerter can only transfer energy y to the grid, ddo not put inv verter AC outpu ut terminal connected to thhe AC load or generator, g prevventing from eq quipment damag ge or personnal injury. The surfaace of the inverrter may becom me hot when it iss working, do not n touch inverter by hand or any part off your body, in n order to prevvent burns; and d please don't set n the inverter orr closed to the inverter. i inflammaable and explossive materials in Litto PV V grid tied invverter is non-isolate high freqquency invererr, thus the inpu ut negative is not allowed to grounding. Litto LT T5000/6000/80000/10000/15000 0/18000/20000H HD series inveerter has natural cooling w way, please make m sure that the installationn of the distan nce between tw wo inverters, greater than 1 m, in order to t avoid overheeating and can't reach the rateed power off inverter outpuut. Litto invverters are conffigurated with WIFI communniction mode, please p make surre signal unnimpeded during installation.

mplete warning labels, please bbe sure to know w and understand d Inverter externnal case has com the meaning off these warningg signs.
