2 April 2012Safety PrecautionsGeneral InformationThe installation of modules requires agreat degree of skill and should only beperformed by qualified licensedprofessionals, including, withoutlimitation, licensed contractors andlicensed electricians.WARNINGAll instructions should be read andunderstood before attempting toinstall, wire, operate, and maintainthe module. Contact withelectrically active parts of themodule such as terminals can resultin burns, sparks, and lethal shockwhether the module is connectedor disconnected.The installer assumes the risk of allinjury that might occur duringinstallation, including, withoutlimitation, the risk of electric shock.The modules generate DC electricalenergy when exposed to sunlightor other light sources. Althoughsingle modules produce only a lowvoltage and current, shocks andburns are still a potential hazard.To avoid the hazard of electricshock and injury, cover the entirefront surface of the modules with adense, opaque material such as acardboard box, during installationand handling of the modules.The shock hazard increases asmodules are connected in parallel,producing higher current, and asmodules are connected in series,producing higher voltages.The shock hazard increases asmodules with nominal open-circuitvoltage (Voc) in excess of 50 V,and/or modules rated formaximum system voltage in excessof 50 V.To avoid the hazard of electricshock, work only in dry conditions,with dry modules and dry tools.Do not stand or step on a moduleto avoid the hazard of injury anddamage to the module.Do not puncture or damage theback sheet of a module, to avoidthe hazard of electric shock andfire.To avoid the hazard of electricshock and injury, children andunauthorized persons should notbe allowed near the installation ofmodules.To avoid the hazard of electricshock and injury, be sure tocompletely ground all modules.To avoid the hazard of electricshock, fire, and injury, do notdisassemble the module, or removeany part installed by themanufacturer.Unauthorized persons—except thequalified licensed professional—should not open the cover of thejunction box to avoid the hazard ofelectric shock.Do not touch terminals while amodule is exposed to light. Providesuitable guards to prevent yourselffrom direct contact with 30 VDC orgreater to avoid the hazard ofelectric shock or injury.When carrying a module, two ormore people should carry it by itsframe and wear non-slip gloves (toavoid injury by a slipping module,to a foot, or cuts by the edge of aframe, and so on).Do not carry a module by its wiresor junction box, to avoid thehazard of electric shock, injury ordamage to the module.Do not drop anything on thesurfaces of a module, to avoid thehazard of electric shock, injury, anddamage.To avoid the hazard of electricshock and fire, be sure that allother system components arecompatible, and they do notsubject the module to mechanicalor electrical hazards.Since sparks may occur, do notinstall the module whereflammable gases or vapors arepresent.Never leave a module unsupportedor unsecured.Do not drop a module.Do not use or install brokenmodules to avoid the hazard of fire,electric shock, and injury.Do not artificially concentratesunlight on a module to avoid thehazard of fire or damage.Do not touch the junction boxterminals to avoid the hazard ofelectric shock and injury.Do not change the wiring of bypassdiodes to avoid the hazard ofelectric shock and injury.Do not disconnect terminals whilemodules generate electricity andconnect electrical load to avoid thehazard of electrical shock.Do not touch a moduleunnecessarily. The glass surfaceand frames get hot. There is a riskof burn.CAUTIONSUse a module for its intendedpurpose only.Do not treat the back sheet orfront surface with paint oradhesives, to avoid reducing its’functionality, damage, inoperableconditions, and other unknowntroubles.GENERAL SAFETYFollow all permission, installation andinspection requirements.Before installing modules, contactthe appropriate authorities todetermine permissions, installationand inspection requirements,which should be followed.Be sure that the construction orstructure (roof, etc.) where themodules are being installed hasenough strength.For modules mounted on roofs,special construction or structuresmay be required to help provideproper installation support.Both roof construction and moduleinstallation design have an effecton the fire resistance of a building.Improper installation maycontribute to fire hazards.Additional devices such as groundfault, fuses, and disconnects maybe required.Do not use modules of differentspecifications in the same system.Follow all safety precautions ofother system components used.INSTALLATIONGeneralPlease read this guide completelybefore installation or use of themodules. This section containselectrical and mechanicalspecifications needed before usingmodules.Modules should be firmly fixed inplace in a manner suitable towithstand all expected loads,including wind and snow loads.Please do not touch the glasssurface of modules to protect fromdirt, because the glass surface iscoated. (If the glass surfacebecomes dirty, see section ofMAINTENANCE.)The drilling and addition of groundholes is permitted, but should beavoided whenever possible toavoid damage to the module.
