General Information
The installation of solar modules requires
a great degree of skill and should only be
performed by qualified licensed
professionals, including, without limitation,
licensed contractors and licensed
electricians.
WARNING
•All instructions should be read and
understood before attempting to
install, wire, operate, and maintain
the photovoltaic module. Contact
with electrically active parts of the
module such as terminals can
result in burns, sparks, and lethal
shock whether the module is
connected or disconnected.
•The installer assumes the risk of
all injury that might occur during
installation, including, without
limitation, the risk of electric shock.
•PV modules generate DC electrical
energy when exposed to sunlight
or other light sources. Although
single modules produce only a low
voltage and current, shocks and
burns are still a potential hazard.
•To avoid the hazard of electric
shock and injury, cover the entire
front surface of the PV modules
with a dense, opaque material such
as a cardboard box, during
installation and handling of the
modules.
•The shock hazard increases as
modules are connected in parallel,
producing higher current, and as
modules are connected in series,
producing higher voltages.
•The shock hazard increases as
modules with nominal open-circuit
voltage (Voc) in excess of 50 V,
and/or modules rated for maximum
system voltage in excess of 50 V.
•To avoid the hazard of electric
shock, work only in dry conditions,
with dry modules and dry tools.
•Do not stand or step on a module
to avoid the hazard of injury and
damage to the module.
•Do not puncture or damage the
back sheet of a module, to avoid
the hazard of electric shock and
fire.
•To avoid the hazard of electric
shock and injury, children and
unauthorized persons should not
be allowed near the installation of
PV modules.
•To avoid the hazard of electric
shock and injury, be sure to
completely ground all modules.
•To avoid the hazard of electric
shock, fire, and injury, do not
disassemble the module, or
remove any part installed by the
manufacturer.
•Unauthorized persons—except the
qualified licensed professional—
should not open the cover of the
junction box to avoid the hazard of
electric shock.
•Do not touch terminals while a
module is exposed to light. Provide
suitable guards to prevent yourself
from direct contact with 30 VDC or
greater to avoid the hazard of
electric shock or injury.
•When carrying a module, two or
more people should carry it by its
frame and wear non-slip gloves (to
avoid injury by a slipping module,
to a foot, or cuts by the edge of a
frame, and so on).
•Do not carry a module by its wires
or junction box, to avoid the
hazard of electric shock, injury or
damage to the module.
•Do not drop anything on the
surfaces of a module, to avoid the
hazard of electric shock, injury,
and damage.
•To avoid the hazard of electric
shock and fire, be sure that all
other system components are
compatible, and they do not
subject the module to mechanical
or electrical hazards.
•Since sparks may occur, do not
install the module where
flammable gases or vapors are
present.
•Never leave a module unsupported
or unsecured.
• Do not drop a module.
• Do not use or install broken
modules to avoid the hazard of fire,
electric shock, and injury.
•Do not artificially concentrate
sunlight on a module to avoid the
hazard of fire or damage.
•Do not touch the junction box
terminals to avoid the hazard of
electric shock and injury.
•Do not change the wiring of
bypass diodes to avoid the hazard
of electric shock and injury.
•Do not disconnect terminals while
PV modules generate electricity
and connect electrical load to
avoid the hazard of electrical
shock.
CAUTIONS
•Use a module for its intended
purpose only.
•Do not treat the back sheet or front
surface with paint or adhesives, to
avoid reducing its’ functionality,
damage, inoperable conditions,
and other unknown troubles.
GENERAL SAFETY
Follow all permission, installation and
inspection requirements.
•Before installing modules, contact the
appropriate authorities to determine
permissions, installation and
inspection requirements, which
should be followed.
•Be sure that the construction or
structure (roof, etc.) where the
modules are being installed has
enough strength.
•For modules mounted on roofs,
special construction or structures may
be required to help provide proper
installation support.
•Both roof construction and module
installation design have an effect on
the fire resistance of a building.
Improper installation may contribute
to fire hazards. Additional devices
such as ground fault, fuses, and
disconnects may be required.
•Do not use modules of different
specifications in the same system.
•Follow all safety precautions of other
system components used.

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.
•The drilling and addition of ground
holes is permitted, but should be
avoided whenever possible to avoid
damage to the module. When
additional ground holes are
necessary, they must not penetrate
the inner side of the aluminum frame.
Caution is advised to avoid
accidentally drilling, scratching, or
penetrating the back sheet surface of
the module. If required, it is
recommended to add additional
ground holes to the outer aluminum
lip area of the module. In such case,
additional ground holes must be at
least 65 mm away from any frame
corner.
•For a non-integral module or panel,
the assembly is to be mounted over a
fire resistant roof covering rated for
the application.
•Appropriate material should be used
for mounting hardware to prevent the
module frame, mounting structure,
and hardware itself from corrosion.
•Install modules where they are not
shaded by obstacles like buildings
and trees. Especially pay attention to
avoid partially shading the modules
by objects during the daytime.
•Please contact your SANYO
Authorized Representative with
questions regarding mounting profiles
for modules if needed.
Notes on Installation
•Clearance of “10 cm” 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.
•We recommend installation methods
shown in Figure 1. In some areas,
local electrical codes may govern the
installation and use of PV modules.
•To avoid the hazard of the electric
shock and fire, do not contact and
damage the back sheet of the module
with mounting bolts.
Operating Conditions
SANYO recommends that modules be
operated within the following Operating

WIRING
General
•All wiring should be done in
accordance with applicable electrical
codes.
•All wiring should be done by a
qualified, licensed professional.
•Wiring should be protected to help
ensure personal safety and to prevent
its damage.
•All modules connected in series
should be of the same model number
and/or type.
•Do not connect modules in parallel
without using a connection box.
•Do not disconnect terminals while PV
modules generate electricity and
connect electrical load to avoid the
hazard of electrical shock.
•To avoid the hazard of electric shock
and sparks, please connect each
cable after confirming the polarity of
them is correct.
Module Wiring
•The maximum number of NKHE-type
modules that can be wired in series is
seventeen (17).
•Modules shall not be wired in parallel
without maximum over current
protection.
•When installing a PV array, the
system design must be completed
with reference to the module electrical
specifications for proper selection of
inverters, fuses, breakers, charging
controllers, batteries and other
storage devices.
•These modules contain factory
installed bypass diodes. If these
modules are connected each other
incorrectly, the bypass diodes, cable,
or junction box may be damaged.
Array Wiring
•The term “array” is used to describe
the assembly of several modules on a
support structure with associated
wiring.
•Use copper wire that is sunlight
resistant and is insulated to withstand
the maximum possible system open
circuit voltage.
•Check your local codes for
requirements.
Earth Ground Wiring
•The kind of the earth construction
shall conform to IEC61730-1.
•Bonding shall be by a positive means,
such as clamping, riveting, bolted or
screwed connections, or welding,
soldering or brazing. The bonding
connections shall penetrate all nonconductive coatings, such as paint,
anodized coatings or vitreous enamel.
•A wiring terminal or bonding location
of module intended to accommodate
a field installed equipment-grounding
conductor shall be identified with the
appropriate symbol (IEC 604175019(DB: 2002-10)) or shall have a
green-colored part.
•Grounding should be carried out by
the attachment to the module or array
frame, to avoid the hazards of electric
shock or fire.
Module Terminations
•A junction box as a terminal
enclosure is equipped for electrical
connections on SANYO modules.
•Modules are equipped with MCTM
plugs as a terminal enclosure. Use
these MC
connections.
•If two or more separable connectors
are provided, they shall be configured
or arranged so that the other and
TM
plugs for electrical
vice-versa will not accept the mating
connector for one, if it will result in an
improper connection.
•Please contact your SANYO
Authorized Representative with
questions regarding other electrical
connections if needed.
Junction Box and Terminals
•Modules equipped with one junction
box contain terminals for both positive
and negative polarity, and bypass
diodes.
•One terminal is dedicated to each
polarity (with the polarity symbols
engraved onto the body of the
junction box) (see Figure 3).
Conduit
•For applications where wire conduits
are used, follow the applicable codes
for outdoor installation of wires in
conduits. Minimum diameter of wire
conduit is 2.5 mm
•Verify that all fittings are properly
installed to protect wires against
damage and prevent moisture
intrusion.
DIODES
Bypass Diodes
•When the modules in series strings
are shaded partially, it may cause
reverse voltage across cells or
modules, because the current from
other cells in the same series is
forced to flow through the shaded
area. This may cause undesirable
heating to occur.
•The use of a diode to bypass the
shaded area can minimize both
heating and array current reduction.
•All SANYO modules are equipped
with factory installed bypass diodes.
The factory installed diodes provide
proper circuit protection for the
systems within the specified system
voltage, so that you do not need any
other additional bypass diodes.
•Contact your SANYO Authorized
Representative for proper diode type,
if it is necessary to add or change
diodes due to system specifications.
MAINTENANCE
•Some maintenance is recommended
to maintain optimal output
performance of the solar modules.
•If the module surface becomes dirty,
it may reduce output power.
•It is recommended to clean the
surface of the module with water and
a soft cloth or sponge.
•A mild non-abrasive detergent may
be applied for persistent dirt.
•It is also recommended to inspect the
electrical and mechanical connections
annually.
