    1 of 26 INTRODUCTION This document provides information on First Solar Series 6 CuRe modules of model types beginning as FS- 6XXX-C (“XXX” references the module power rating) for system designers, installers, and maintenance personnel. Model types including ‘A’ contain an anti-reflective coating (ARC) on the front side surface.

  • Page 5: Safety

    All instructions and safety information should be read and understood before attempting to handle, install, or electrically connect First Solar modules. Failure to follow safety, installation, and handling instructions may result in injury. Only qualified personnel should install, operate, or maintain PV modules or systems.
  • Page 6 DANGER Reverse currents higher than the rated values for a First Solar module, may result in module failure, including module breakage due to RCOL. Extreme and continuous RCOL conditions may cause a fire or create electrical shock hazards. To avoid RCOL: Maintain equivalent voltage in parallel strings by installing an equal number of modules ►...

  • Page 7: Regulatory Compliance

    REGULATORY COMPLIANCE It is the responsibility of the installer and/or system integrator to ensure compliance with all local structural and electrical codes, which may be applicable to the installation and use of First Solar Series 6 CuRe modules. For systems installed in North America, First Solar Series 6 CuRe modules are Listed by a Nationally Recognized Test Laboratory (NRTL) to UL 61730, the standard for Flat-Plate Photovoltaic Modules and Panels.
