2SAFETY PRECAUTIONS All instructions should be read andunderstood before attempting toinstall, wire, operate, and maintainthe module. The installation of modules requiresa great degree of skill and shouldonly be performed by qualifiedlicensed professionals, including,without limitation, licensed contrac-tors and licensed electricians. The installer assumes the risk of allinjury that might occur during in-stallation, including, without limita-tion, the risk of electric shock. Before installing modules, contactthe appropriate authorities to de-termine permissions, installationand inspection requirements, whichshould be followed. Be sure that the construction orstructure (roof, etc.) where themodules are being installed hasenough strength. Both roof construction and moduleinstallation design have an effect onthe fire resistance of a building.Improper installation may contrib-ute to fire hazards. Additional de-vices such as ground fault, fuses,and disconnects may be required. For a non-integral module or panel,the assembly is to be mounted overa fire resistant roof covering ratedfor the application. For modules mounted on roofs,special construction or structuresmay be required to help provideproper installation support. Do not install the module whereflammable gases or vapors are pre-sent. Do not use modules of differentspecifications in the same system. Follow all safety precautions ofother system components used. In some areas, local electrical codesmay govern the installation and useof modules.WARNINGTo avoid the hazard of electric shock,sparks, fire and injury The modules generate DC electricalenergy when exposed to sunlight orother light sources, so cover theentire front surface of the moduleswith a dense, opaque material suchas a cardboard box, during installa-tion and handling of the modules. The shock hazard increases as mod-ules are connected in parallel, pro-ducing higher current, and as mod-ules are connected in series, produc-ing higher voltages. The shock hazard increases as mod-ules with nominal open-circuit volt-age (Voc) in excess of 45 V, and/ormodules rated for maximum systemvoltage in excess of 45 V. Wear suitable clothing, gloves andguards to prevent from direct con-tact with 30 VDC or greater. Work only in dry conditions, withdry modules and dry tools. Children and unauthorized personsshould not be allowed near theinstallation of modules. Do not puncture or damage theback sheet of a module. Do not usethe PV module and make a replace-ment, when scratch exposing con-ductive part is found on the backsheet. Do not disassemble the module, orremove any parts installed by themanufacturer. Do not open a junction box's lid. Do not touch the junction box ter-minals. Do not change the wiring of bypassdiodes. Do not connect or disconnect termi-nals while modules generate elec-tricity and connect electrical load. Never leave a module unsupportedor unsecured.CAUTIONSTo avoid the hazard of injury, burn anddamage to the module Use a module for its intended pur-pose only. Be sure that all other system com-ponents are compatible, and theydo not subject the module to me-chanical or electrical hazards. Do not artificially concentrate sun-light on a module. Do not stand or step on a module. When carrying a module, two ormore people should carry it by itsframe and wear non-slip gloves. Do not carry a module by its wiresor junction box. Do not drop a module. Do not drop anything on the sur-face of a module. Do not hit the back sheet of a mod-ule by the connector or otherthings. Do not disassemble a module, at-tempt any repair, open the junctionbox cover, nor remove any partsinstalled by Panasonic. There are nouser serviceable parts within themodule or junction box. Do not treat the back sheet or frontsurface with paint or adhesives. Do not use or install broken mod-ules. If you find a breakdown suchas glass breakage, contact the pro-fessional installer to replace itpromptly. Do not touch a module unnecessari-ly. The glass surface and frames gethot.
