EN-Rev IM/IEC-AM-EN/3.6 Copyright © March 2017. Canadian Solar Inc.6 |5.0MODULE INSTALLATIONPRECAUTIONARY MEASURES ANDGENERAL SAFETY· Prior to installing modules please obtaininformation about any requirements andnecessary approvals for the site, installation andinspection from the relevant authorities.· Check applicable building codes to ensure that theconstruction or structure (roof, facade, support,etc.) can bear the module system load.· CS-series solar modules have been qualified forApplication Class A (equivalent to Safety Class IIrequirements). Modules rated under this classshould be used in systems operating at voltageabove 50 V or power above 240 W, where generalcontact access is anticipated.· When installing modules, please ensure the sup-porting roof has a fire resistant roof covering ratedfor the application. Canadian Solar Inc. modulesare listed as Class C under the UL790 standard.· The fire rating for this module is only valid whenthe product is installed as specified in the mechani-cal mounting instructions.ENVIRONMENTAL CONDITIONS· The module is intended for use in generalopen-air climates, as defined in IEC 60721-2-1:Classification of environmental conditions Part-2-1:Environmental conditions appearing in nature -Temperature and humidity.· Please consult the Canadian Solar Inc. technicalsupport department for more information on theuse of modules in special climates.Do not install modules near nakedflames or flammable materials.Do not immerse modules in water orconstantly expose modules to water(either fresh or salt) (i.e. from fountains,sea spray).· Exposing modules to salt (i.e. marine environments)or sulfur (i.e. sulfur sources, volcanoes) incurs therisk of module corrosion.· Failure to comply with these instructions will voidCanadian Solar Inc. warranty.INSTALLATION REQUIREMENTS· Ensure that the module meets the general technicalsystem requirements.· Ensure that other system components do notdamage the module mechanically or electrically.· Modules can be wired in series to increase voltageor in parallel to increase current. To connect modulesin series, connect the cables from the positiveterminal of one module to the negative terminalof the next module. To connect in parallel, connectthe cables from the positive terminal of one modu-le to the positive terminal on the next module.· The quantity of bypass diodes in the module'sjunction box may vary depending on the modelseries.· Only connect the quantity of modules that corres-ponds to the voltage specifications of the invertersused in the system. Modules should not beconnected together to create a voltage higher thanthe maximum permitted system voltage, evenunder the worst local temperature conditions (seeTable 1 for the correction coefficients that apply toopen-circuit voltage).· A maximum of two strings can be connected inparallel without the need to incorporate an over-current protection device (fuses, etc.) in serieswithin each string. Three or more strings can beconnected in parallel if an appropriate, certifiedover-current protection device is installed in serieswithin each string.· Only modules with similar electrical outputsshould be connected in the same string to avoid orminimize mismatch effects in arrays.· To minimize risk in the event of an indirect light-ning strike, avoid forming loops when designingthe system.
