conductivity or for use as grounding devices and should be used only
for maintaining mechanical connections and holding electrical
grounding devices in the proper position for electrical conductivity.
Such devices, where supplied with the module and evaluated through
the requirements in UL1703, may be used for grounding connections
in accordance with the instructions provided with the module.
Grounding Using Existing Ground Hole (Figure 4, 1954381-2)
The grounding clip (SolKlip grounding Clip Assemblies 1954381-2, Tyco
electronics corp., E69905) assembly consists of a slider, base and #8-32 or
#10-32 screw(Material; stainless steel) and hex nut (Material; chromate
treatment carbon steel).
1. Place the grounding onto the frame, making sure that the screw
straddles the grounding hole.
2. Thread the hex nut onto the end of the screw, then using a 3/8” or
5/16” wrench, tighten the nut. Recommended torque is between
2.3(21) and 2.8 Nm (25lbf.in.).
3. Insert the grounding wire into the wire slot. Press down on both
ends of the wire (the wire slot will cause the wire to form a slight
curve). The grounding cables can be insulated with green colored
insulation or insulated with green with yellow stripe(s) insulation.
The conductor grounding cables should be 12 AWG (Insulated for
90
°
C (194
°
F) Min.).
4. Manually, or using channel lock pliers, push the slider over the
base until it covers the base. This will terminate the wire.

. MOUNTING
Please make sure that all the information described in the installation
manual is still valid and proper for your installation. The approved way to
mount SHARP PV modules to a support structure is described in this
INSTALLATION MANUAL. Although SHARP does not specify or warrant
frame clips or clamps, using frame clips (not provided) or clamps (not
provided) is 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.
The SHARP module guaranty may be void if customer-selected frame clips
are improper or inadequate for 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 guaranty. These
mounting methods are designed to allow module loading of 2400Pa. the
module has passed a snow load test of 5400Pa according to
IEC61215.Support structures that PV modules are mounted on should be
rigid. SHARP PV modules are designed to ensure optimal electrical
performance under the condition that they are mounted on rigid support
structures. Deformation of support structure may damage PV module with
its electric performance. When mounting the module on structure, ensure
that no corner has a displacement of more than 2mm (0.08in) per every
1000mm (39.37in) of the diagonal.
( for US market )
The modules have been evaluated by UL according to UL 1703 for
maximum positive or negative design loading of 30lbs.ft
2
.
A clearance of at least 4.5in (recommended) is provided between
modules frame and the surface of the wall or roof. If other mounting
means are employed this may affect the UL Listing or the fire class
ratings.
8. MAINTENANCE
SHARP PV modules are designed for long life and require very little
maintenance. If the angle of the PV module is 5 degrees or more, normal
rainfall is usually sufficient to keep the module glass surface clean under
most weather conditions. If dirt build-up becomes excessive, clean the glass
surface only with a soft cloth using water. If cleaning the back of the module
is required, take utmost care not to damage the back side materials. In
order to ensure proper operation of the system, please check all wiring
connections and the condition of the wire insulation periodically.
9. DISPOSAL
Dispose photovoltaic modules properly. For Information
about the proper disposal, contact your local recycling
site.
INSTALLATION MANUAL -PHOTOVOLTAIC MODULES-
1. INSTALLATION
Please review the descriptions and drawings carefully; not mounting the
modules according to one of these methods may void your guaranty. These
mounting methods are basically designed to allow module loading of
±2400Pa (50lbs.ft

).
( for US market )
The modules have been evaluated by UL according to UL 1703 for
maximum positive or negative design loading of 30lbs.ft

.
Mounting Using Clips: Clamping on Longer Frame (Figure2)
The modules can be mounted using clips (clamps) designed for solar
modules as defined in the following Figures. Note that the mounting clips
should meet the required dimensions as defined in the Figure1. Note that
the
CLIP CENTER POSITION (e)
is important as specified in the Figure2.
The module must be supported on the array system and should overlap
the array rail by at least 10mm (0.39in). The array rails (see pointillist
image, row or vertical row) must support the bottom of the frames and
must be continuous piece (no breaks in the rail).
