3Safety PrecautionsGeneral InformationThe installation of solar modulesrequires a great degree of skill andshould only be performed by qualifiedlicensed professionals, including,without limitation, licensed contractorsand electricians.WARNING All instructions should be read andunderstood before attempting toinstall, wire, operate, and maintain aphotovoltaic module. Contact with electrically active partsof the module such as terminals canresult in burns, sparks, and lethalshock whether the module isconnected or disconnected. The installer assumes the risk of allinjury that might occur duringinstallation, including, withoutlimitation, the risk of electric shock. The modules generate DC (directcurrent) electrical energy whenexposed to sunlight or other lightsources. Even a single moduleproduces enough voltage andcurrent, to cause shocks and burns ifsafety precautions are not followed. The shock hazard increases asmodules are connected in parallel,producing higher current, and asmodules are connected in series,producing higher voltages. Do not hit the back sheet of amodule by the connector or otherthings. To avoid the hazard of electricsparks, shock, fire, burns, damageand injury, work only in dryconditions, with dry modules anddry tools. In order to avoid submerging cablesand connectors in the water, cablesmust be fixed either to the moduleframe using cable fixing holes or tothe mounting structure. Do not stand or step on modules. Donot puncture, cut, scratch ordamage the backsheet of a module.Backsheet damage will void amodule’s Limited Warranty and maycause fire. Never use modules with adamaged back sheet. Do not allow children andunauthorized persons near theinstallation or storage site ofmodules. Completely ground all modules. Do not disassemble a module,attempt any repair, open thejunction box cover, nor remove anyparts installed by Panasonic. Thereare no user serviceable parts withinthe module or junction box. Unauthorized persons - except thequalified licensed professional -should not perform any electricalwork, including wiring. Wear suitable clothing, guards, eyeprotection and gloves to preventyou from direct contact with 30 VDCor greater. Wear non-slip gloves and carrymodules by the frame using bothhands. Do not attempt to carry amodule by yourself. Do not carry a module by its wires orjunction box. Do not drop anything on the surfaceof a module. Ensure all system components arecompatible, and they do not subjectthe module to mechanical orelectrical hazards. Sparks may occur; do not installmodules where flammable gases orvapors are present. Never rest or leave a moduleunsupported or unsecured. Do not drop modules. Do not use or install broken modules. Do not artificially concentratesunlight on a module. Do not touch the junction boxterminals. Do not change the wiring of bypassdiodes. Do not touch a module unnecessarily.The glass surface and frames get hot.There is a risk of burn.CAUTIONS Use a module for its intendedpurpose only. Do not treat the back sheet, frame,or front surface with paint oradhesives, to avoid reducing its’functionality, damage, and causinginoperable conditions, and otherunknown troubles. Do not insert PV cable between backside and mounting structure rail.GENERAL SAFETY Follow all permissions, installationand inspection requirements. Before installing modules, contactthe appropriate authorities havingjurisdiction to determine permissions,installation and inspectionrequirements, which should befollowed. Electrically ground modules for allsystems of any voltage. If nototherwise specified, it isrecommended that requirements ofthe latest National Electrical Code(USA) or Canadian Electric Code(Canada) or other national orinternational electrical standards befollowed. Refer to “Earth GroundWiring” section for moreinformation. Be sure that the building or structure(roof, façade, etc.) where themodules are being installed hasenough strength to support the loadof the modules. For modules mounted on roofs,special structures may be required tohelp provide proper installationsupport. The fire rating of this module is validonly when mounted in the mannerspecified in the mechanicalmounting instructions. Both, roof construction and moduleinstallation design have an effect onthe fire resistance of a building.Improper installation may contributeto fire hazards. The models in this instructions aresuitable to maintain the System FireClass Rating A when used with aListed mounting system and a roofcovering that have been rated as aClass A System when installed on asteep slope roof and/or a low sloperoof with "Type 2" modules. Additional devices such as groundfault, fuses, and disconnects may berequired. Do not use modules of differentspecifications in the same system. Follow all safety precautions ofother system components which areused.UL Listing InformationTo satisfy UL requirements, wheninstalling the modules, be sure to:1) Use only stranded or solid coppersingle–conductor sunlight-resistantcable rated for outdoor use (e.g.type UF or USE) , for all wiring that isexposed to weather.
