GENERAL INSTALLATION MANUAL e ee FOR PERLIGHT PV MODUELS ee ee 1 INTRODUCTION This installation Manual contains essential information for the electrical and mechanical installation that your must know before installing PERLIGHT PV modules This also contains safety information you need to be familiar with All the information described in this manual are the intellectual property of PERLIGHT and based on the technologies and experiences that have been acquired and accumulated in the long history of PERLIGHT This document does not constitute a warranty expressed or implied PERLIGHT does not assume responsibility and expressly disclaims liability for loss damage or expense arising out of in anyway connected with installation operation use or maintenance of the PV modules No responsibility is assumed by PERLIGHT for any infringement of patents or other rights of third parties that may result from use of PV module PERLIGHT reserves the right to make changes to the product specifications or installation manual without prior notice 2 GENERAL INFORMATION INCLUDING WARING AND SAFETY The installation of PV modules requires a great degree of skill and should only be performed by a qualified licensed professional including licensed contractors and licensed electricians Please be aware that there is a serious risk of various types of injury occurring during the installation including the risk of electric shock All PERLIGHT modules are equipp
