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 equipped with a permanently attached junction terminal
box that will accept variety of wiring applications or with a special cable assembly
for ease of installation, and they do not require assembly. <GENERAL SAFETY>
1. Consult local codes and other applicable laws concerning required permits on
<GENERAL WARNING> regulations concerning installation and inspection requirements.

10.MOUNTING
Please make sure that all the information described in the installation manual is
still valid and proper for your installation. The mounting method has been verified
by PERLIGHT and NOT CERTIFIED by a third party organization.
The approved way to mount PERLIGHT PV modules to a support structure is
using the bolt holes provided as described in the Specifications. Although
PERLIGHT does not specify or warrant frame clips or clamps, using frame clips
(not provided ) or clamps module (not provided ) is also possible when they are
designed for PV modules and with minimum dimensions on the sides of the
module in accordance with the instructions and drawings provided. If using frame
clips or clamps, the modules should be fixed rigidly and there shall be no damage
to the modules by deforming mounting structure against design load. PERLIGHT
does not specify or warrant frame clips. The PERLIGHT module warranty may be
void if customer-selected trame clips which are improper or inadequate with
respect to the module properties(including strength or material)or installation. Note
that if metal clips are used, there must be a path to ground from the clips.(for
instance, using star washers in the clip hardware set). Please review the
descriptions and drawings carefully; not mounting the modules according to one of
these methods may void your warranty. These mounting methods are designed to
allow module loading of 2400pa.
11.MAINTENANCE
The modules are designed for long life require very little maintenance. If the angle
