Follow all safety precautions of other
•
system components which are used.
UL Listing Information
To satisfy UL requirements, when installing
the modules, be sure to:
1)
Use only stranded or solid copper
single–conductor type PV wire or USE-
2 cable, 12AWG or larger conductors,
rated 600V, 90℃, sunlight resistant, for
modules and interconnect wiring that is
exposed to weather.
2)
Observe the requirements described in
sections labeled INSTALLTION and
SPECIFICATIONS.
INSTALLATION
General
Please read this guide completely before
installation or use of the modules. This
section contains electrical and mechanical
specifications needed before using your
SANYO PV modules.
Modules should be firmly fixed in place
•
in a manner suitable to withstand all
expected loads, including wind and
snow loads.
Metals used in locations that are
•
exposed to moisture shall not be
employed alone or in combinations that
could
result
in
corrosion.
Install modules where they are not
•
shaded by obstacles like buildings and
trees. Especially pay attention to avoid
partially
shading
the
objects during the daytime.
Contact an Authorized Representative
•
with questions regarding mounting
profiles for modules if needed.
Notes on Installation
Clearance between the roof surface
•
and module frame is required to allow
cooling air to circulate around the back
of the module. This also allows any
condensation or moisture to dissipate.
Install modules so that air can circulate
between the roof and the module.
Leave 1 inch of clearance between the
•
roof and the module frame. If other
mounting means are employed this
may effect the temperature of the panel.
SANYO recommends the installation
•
method and mounting profile shown in
Figure 1.
A module should be attached on a
•
mount or support structure rail by metal
clamps. The metal clamp must fulfill
the following specifications.
Size:not less than 1.5" (38 mm) width
Thickness :not less than 0.12"(3 mm)
Material: aluminum alloy
Recommendation of bolt torque range:
•
16N.m to 20N.m.
Operating Conditions
SANYO requires that modules be operated
within the following Operating Conditions:
1)
Terrestrial applications only—no outer
space or Special Conditions (see
below).
2)
The ambient temperature must be
within –20°C (-4°F) to 46°C (115°F).
The temperature limits are defined as
the Monthly Average High or Low of
the installation site.
3)
The
installation site should be less than
2,880N/m
4)
Some environmental conditions could
apply. Please refer to Sanyo's warranty
exclusions.

by a factor of 1.25 when determining
the
