These <br />components should not be modified ortampered with in any way. <br />• Do not'allow unauthorized persons near the installation site or storagearea of modules. <br />• Do ndt place modules on topbf one another. <br />• Do not placeany load on the module or twistthe module frame. <br />• Do not stand, step, walk, or jumpen the moduJe. <br />• Do not drop or place objectspn the modules such as tools. <br />• Do not handle modules with bare hands and avoid scratches, handling marks, or anydamage especially to the frontglass of <br />the module, backsheet, or electrical components. <br />• Do not mark the modules with sharp instruments. <br />• Do not leave a module unsupported or unsecured. <br />• Do notmodify module frames in any way. <br />3.2 SAFETY <br />The following»safetyguidelines and best practices should be followed: <br />• All installations must be performed in compliance withiall applicable regional and localelectrical codes orother national or <br />international electrical standard&. <br />• Use insulated toolsduring installation, troubleshooting and maintenance of photovoltaic modules. <br />• Wearsuitable protection to preventdirectcontact with module's electrical outputand mechanical sharp edges. <br />• Cover the front of the modules with an opaque material to stop production of electricjty when installing or working with a <br />moduleorwiring. <br />• Modules connected in a series should not be disconnected under illumination. Disconnecting modules under illumination may <br />causeelectrical aicing which may result in burns, fires brother problems. <br />• Follow industry best practices when commissioning, trouble shooting, disconnecting, orconnectinga PV system. <br />• Trouble shooting should include planning, checking, disconnecting, cause seeking,replacement, and record keeping. <br />• Dn notinctall nrhanrile themorltilpv nrthpirromponpnt<\Mhen they arp wet Arrltiring pprior·knf high wind <br />• Do notattempt to disassemble, repair, or open any part of the module including junction box or sub-components. <br />• Do not artificially concentrate sunlight on a module. <br />• Do not install or handle any br6ken modules. I f a module is broken, orthe back sheet is torn, contactwith the surface or <br />frame can cause an electrical shock. <br />e Do not wear rings, jewelry, watches, orother metallic items while working with photevoltaic modules.eping. <br />3.3 MAINTENANCE <br />Checkmodules, glass, and frames for damage. Regularly inspectall MEMC Silvantis S61ar Modules for safeelectrical connections, <br />sound mechanical connections, and freedom from shading and corrosion. If dirt or debris buildup becomes excessive, periodically <br />clean the glass only witb a soft cloth using mild, non-abrasive detergentand water. When using mild cleaning liquids, a neutral pH in <br />the range Of 6.0 to,8.0 is recommended. Chemicals with pH less than 6.0 or greater than 8.0 should be avoided as it may damage <br />the glass surface and or the AR coating. Please consult with system designer to decide the cleaning and inspection frequency <br />----*tording to local environmental-conditions. <br />Do not power wash or use harsh cleaning materials or objects such as scouting powder, steel wool, scrapers, blades, or,ofher sharp <br />instruments to clean the glass surface o f the module. Use of such materials will ihvalidate the product warranty. <br />WARNING: Use caution when cleaning the back surface of the module to avoid penetfating thesubstrate materials. <br />© Copyright 201 2 MEMC Electronic Marerial <br />It
