SAFETY PRECAUTIONS
• All instrucons should be read and understood
before aempng to install, wire, operate, and
maintain the module.
• The installaon of modules requires a great
degree of skill and should only be performed by
qualied licensed professionals, including,
without limitaon, licensed contractors and
licensed electricians.
• The installer assumes the risk of all injury that
might occur during installaon, including,
without limitaon, the risk of electric shock.
• Before installing modules, contact the appropri-
ate authories to determine permissions,
installaon and inspecon requirements, which
should be followed.
• Be sure that the construcon or structure (roof,
etc.) where the modules are being installed has
enough strength.
• Both roof construcon and module installaon
design have an eect on the re resistance of a
building. Improper installaon may contribute
to re hazards. Addional devices such as
ground fault, fuses, and disconnects may be
required.
• For a non-integrated module, the assembly is
to be mounted over a re resistant roof cover-
ing rated for the applicaon.
• For modules mounted on roofs, special con-
strucon or structures may be required to help
provide proper installaon support.
• Do not install the module where ammable
gases or vapors are present.
• Do not use modules of dierent specicaons
in the same system.
• Follow all safety precauons of other system
components used.
• In some areas, local electrical codes may gov-
ern the installaon and use of modules.
WARNING
To avoid the hazard of electric shock, sparks, re and
injury
• The modules generate DC electrical energy
when exposed to sunlight or other light
sources, so cover the enre front surface of the
modules with a dense, opaque material such as
a cardboard box, during installaon and han-
dling of the modules.
• The shock hazard increases as modules are
connected in parallel, producing higher current,
and as modules are connected in series, pro-
ducing higher voltages.
• The shock hazard increases as modules
with nominal open-circuit voltage (Voc) in
excess of 45 V, and/or modules rated for maxi-
mum system voltage in excess of 45 V.
• Wear suitable clothing, gloves and guards to
prevent from direct contact with 30 VDC or
greater.
• Work only in dry condions, with dry modules
and dry tools.
• Children and unauthorized persons should not
be allowed near the installaon of modules.
• Do not puncture or damage the back sheet of a
module. In case of a scratch on the back sheet,
please replace the module and discard the
scratched one. A scratch on the back sheet
poses a risk of exposing conducve parts.
• Do not disassemble the module, or remove any
parts installed by the manufacturer.
• Do not open a juncon box's lid.
• Do not touch the juncon box terminals.
• Do not change the wiring of bypass diodes.
• Do not connect or disconnect terminals while
modules generate electricity and connect
electrical load.
• Never leave a module unsupported or unse-
cured.
CAUTIONS
To avoid the hazard of injury, burn and damage to
the module
• Use a module for its intended purpose only.
• Be sure that all other system components are
compable, and they do not subject the mod-
ule to mechanical or electrical hazards.
• Do not arcially concentrate sunlight on a
module.
• Do not stand or step on a module.
• When carrying a module, two or more people
should carry it by its frame and wear non-slip
gloves.
• Do not carry a module by its wires or juncon
box.
• Do not drop a module.
• Do not drop anything on the surface of a mod-
ule.
• Do not hit the back sheet of a module by the
connector or other things.
• Do not disassemble a module, aempt
any repair, open the juncon box cover, nor
remove any parts installed by Panasonic. There
are no user serviceable parts within the module
or juncon box.
• Do not treat the back sheet or front surface
with paint or adhesives.
• Do not use or install broken modules. If you
nd a defect e.g. a glass breakage, please
contact a professional PV installer to replace
the module right away.
• Do not touch a module unnecessarily. The glass
surface and frames get hot.

MODULE SPECIFICATIONS
• Module specicaons are shown in Table 1 and
Figure 1. (Electrical specicaons, mechanical
specicaons, module dimensions)
1) Rated electrical characteriscs are within the
range of +10% to -5% of the values measured at
Standard Test Condions (STC). Irradiance of
1000W/m2, 25±2° cell temperature, AM1.5
and solar spectral irradiance according to IEC
60904-3.
2) Under normal condions, a module may experi-
ence condions that produce more current
and/or voltage than reported at standard
component test condions. Accordingly, the
values of Isc and Voc should be mulplied by a
factor of 1.25 when determining voltage
rangs, conductor capacies, fuse sizes, and
size of controls connected to the module out-
put.
3) The current output for the modules shown in
the Specicaons is measured at Standard Test
Condions. These condions may not be fre-
quently observed in actual pracce.

STANDARDS
VBHNxxxSJ and VBHNxxxKJ series comply with the
requirements of IEC61215, IEC61730-1, IEC61730-2
and the CE mark.
APPLICATION CLASS OF PRODUCT
HITTM are applied to applicaon class A and safety
class II. It may be applicated in systems operang at
greater than 50 VDC or 240 W, where general contact
access is ancipated.
FIRE CLASS OF PRODUCT
The re rang of this module is valid only when
mounted in the manner specied in the mechanical
mounng instrucons.
HITTM ll re class C that provides to IEC61730-2.
Class C roof coverings are eecve against light re
test exposures. Under such exposures, roof coverings
of this class aord a light degree of re protecon to
the roof deck, do not slip from posion, and are not
expected to produce ying brands.
JUNCTION BOX AND TERMINALS
• Modules equipped with one juncon box
contain terminals for both posive and nega-
ve polarity, and bypass diodes.
• One terminal is dedicated to each polarity (with
the polarity symbols engraved onto the body of
the juncon box) (see Figure 2).
BYPASS DIODE
• When the modules in series strings are shaded
parally, it may cause reverse voltage across
cells or modules, because the current from
other cells in the same series is forced to ow
through the shaded area. This may cause unde-
sirable heang to occur.
• The use of a diode to bypass the shaded area
can minimize both heang and array current
reducon.
• All modules are equipped with factory installed
bypass diodes. The factory installed diodes
provide proper circuit protecon for the sys-
tems within the specied system voltage, so
that you do not need any other addional
bypass diodes.
• Specicaons of bypass diodes for the
VBHNxxxSJ modules are as follows:
Number of bypass diode: 4 diodes
Number of series cells per bypass diode: 24
cells / diode (See Figure 3).
MECHANICAL LOADING
The method oers a maximum load as shown in the
table “Mount locaon and load resistance” in Figure 1

MODULE INSTALLATION
• Install modules where they are not shaded by
obstacles like buildings or trees. Especially pay
aenon to avoid parally shading the modules
by objects during the dayme. If the PV module
is always partly shaded, hot spots may occur
which can destroy the PV module.
• Water stains might be caused when rain water
remains on the glass surface for a long me. To
avoid water stains, Panasonic recommends to
install modules at a slope steeper than the
water gradient.
• Modules should be rmly xed in place in a
manner suitable to withstand all expected
loads, including wind and snow loads.
• The modules should be mounted basically at
the four (4) quarter points by the means shown
in Figure 1, and based on installaon methods
shown in Figure 4.
• Metals used in locaons that are exposed to
moisture shall not be employed alone or in
combinaons that could result in deterioraon
or corrosion.
• Clearance of 10cm 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 condensaon or moisture
to dissipate. Install modules so that air can
circulate between the roof and the module.
• Do not contact a p of a mounng bolt to the
back sheet of the module when xing the
module to the mounng structure rail.
• Appropriate material should be used for
mounng hardware (the module frame,
mounng structure, and hardware) to prevent
itself from corrosion.
• Please contact your Panasonic Authorized
Representave with quesons regarding
mounng proles for modules if needed.

WIRING
GENERAL
• All wiring should be done in accordance with
applicable electrical codes.
• All wiring should be done by a qualied, li-
censed professional.
• Wiring should be protected to help ensure
personal safety and to prevent its damage.
• Please connect each cable aer conrming the
polarity of it is correct.
• Connectors between modules must be inserted
unl they click.
• When connecng the connectors, please make
sure that they are clean and not contaminated
with water, sand etc. Please keep in mind that
if you leave the connector in a non-connected
state for a long period of me, contaminaon is
likely to occur.
• If an extreme load is applied to the cable, the
cable may come o the juncon box or the
connectors. Please be careful that there is no
heavy load applied to the cable.
• When xing the cable, make sure that the
minimum bending radius of the cable is 30 mm
or more.
• Do not disconnect terminals while modules
generate electricity and connect electrical load
to avoid the hazard of electrical shock.
• Cable conduits should be used in locaons
where the wiring is inaccessible to children or
small animals.
• These modules contain factory installed bypass
diodes. If these modules are connected to each
other incorrectly, the bypass diodes, cables, or
juncon box may be damaged.
• Please contact your Panasonic Authorized
Representave with quesons regarding other
electrical connecons if needed.
MODULE WIRING
• All modules connected in series should be of
the same model number and/or type.
• The number of VBHNxxxSJ and KJ modules, that
can be wired in series, is recommended to be
twelve (12) or fewer. If connecng thirteen (13)
modules and more in series, check local tem-
perature condions to ensure compliance with
maximum system voltage limitaons.
• Do not connect modules in parallel without
using connecon devices that connect to ap-
propriate FUSE for each series string or each
module. For the installaon of connecon
devices, refer to the installaon manual of
connecon devices.
• Do not connect modules in parallel without
maximum over current protecon.
ARRAY WIRING
• The term “array” is used to describe the assem-
bly of several modules on a support structure
with associated wiring.
• When installing a PV array, the system design
must be completed with reference to the
module electrical specicaons for proper
selecon of inverters, fuses, breakers, charging
controllers, baeries and other storage devices.
• Modules are equipped with SMK connectors
(P51-5H/R51-5) as a terminal enclosure. Use
these SMK connectors for electrical connec-
ons.
• Use copper wire which is insulated to withstand
the maximum possible system open circuit
voltage. For applicaons where wire conduits
are used, follow the applicable codes for out-
door installaon of wires in conduits. Minimum
diameter of wire conduit is 4 mm2. The temper-
ature rang of the conductor is –40—90 °C.
• In order to avoid submerging cables and con-
nectors in the water, cables must be xed
either to the module frame using cable xing
holes or to the mounng structure. Also, if the
cable is not secured, an external impact may
aect the cable from the outside, and the
module may be damaged.
• Do not insert a PV cable between back side and
mounng structure rail. When snow weight is
applied to the module, load may be applied to
the cable.
• Verify that all ngs are properly installed to
protect cables against damage and prevent
moisture intrusion.
• We recommend installing a lightning rod and
SPD (Surge protecon device) to reduce dam-
age or break-down to the PV module caused by
lightning.
• Check your local codes for requirements.
EARTH GROUND WIRING
Completely ground all modules.
When grounding the modules, please use a hole near
the ground mark displayed on the frame. For metal
parts for grounding, consider a combinaon that does
not cause corrosion due to dissimilar metal contact.

INSTALLATION
GENERAL
Please read this guide completely before installaon
or use of the modules.
OPERATING CONDITIONS
Panasonic recommends that modules be operated
within the following Operang Condions. An installa-
on locaon with condions beyond the Operang
Condions or with other Special Condions (see
below) should be avoided. Operang Condions of
Panasonic modules are as follows:
1) The modules should be operated only in terrestrial
applicaons. No space or other special condions.
2) The ambient temperature should be within –20°C
to 40°C.
3) The relave humidity should be within 45% to 95%.
4) The wind pressure load of the installaon site
should be less than the load resistance shown in
“Mount Locaons and Load Resistance” table in
Figure 1.
SPECIAL CONDITIONS
Panasonic doesn't recommend to install modules in
areas such as below circumstance:
1) The ambient temperature and installaon place are
dierent from the recommended Operang Condi-
ons.
2) Coastal areas where modules come in direct con-
tact with salt water.
3) Heavy snow falls areas.
4) Sand and dust damage is excessive at the installa-
on place. Heavy dirt areas by sand or dust (e.g.;
desert, a quarry, etc.)
5) Installaon in places where there is a concern
about deterioraon of modules such as heavy air
polluon, chemically acve vapors, acid rain, and/or
soot, ammonia gas, etc.
UNPACKING AND HANDLING
• Do not hit the back sheet of a module by the
connector when unpacking and handling.
• Please do not expose the connector to rain
water and dust.
• To avoid the damage of the back sheet by the
connector, x the cables to the frame with tape
aer unpacking. (refer to Figure 4)
• Do not handle modules by their cables or
juncon box. Handle them by the frame with
both hands in any situaon.
• The an-reecon glass of the module is easy
to be soiled, when it is grasped by hand or hand
gloves. So it is recommended to hold cardboard
or frames when carrying or installing the solar
module. When cables and connectors touch the
surface of the glass, it may soil the surface too.
It is also recommended to avoid contact of
cables and connectors with surface of the glass.
(If the glass surface becomes dirty, see secon
of "an-reecon glass surface cleaning".)

MAINTENANCE
• In order to maintain the opmum output of the
module quality and safety, please conduct
periodic inspecon or cleaning.
• It is also recommended to inspect the electrical
and mechanical connecons annually.
• If you need electrical or mechanical inspecon
or maintenance, it is recommended to have a
licensed authorized professional carry out the
inspecon or maintenance to avoid the hazards
of electric shock or injury.
ANTI-REFLECTION GLASS SURFACE
CLEANING
• Light dirt that does not shield light completely,
does not signicantly degrade power genera-
on performance, but if the module surface
becomes dirty, it may reduce output power.
Malfuncons or hotspots may occur.
• It is recommended to clean the surface of the
module with water and a so cloth or sponge.
• When cleaning with neutral glass detergent or
weak alkaline glass detergent, it is recommend-
ed to start with smallest area and from the
edge of solar module in order to check no
damage occurs to the glass.
• Aer that, clean surface of glass with wet and
clean cloth.
• Recommended detergents: "Glass Magiclean"1
or "Windex® Original"2
1 Glass Magiclean is a trademark of Kao Corporaon.
2 Windex® is a trademark of SC Johnson & Son,Inc.
• It is recommended to read carefully the manu-
als of detergent and understand notes on usage
and rst-aid treatment.
• To remove persistent dirt, the module can be
washed with a micro-ber cloth and ethanol.
• Never use abrasive detergent, strong alkaline
detergent, strong acid detergent or a detergent
which forms a protecve layer on the surface of
the glass to clean any part of the module. The
performance of a solar module may be re-
duced. Please be very careful since the guaran-
tee will not cover damages caused by deter-
gents.
• When cleaning the PV module, please do not
put detergent on the juncon box or connector.
If detergents and chemical substances adhere,
the juncon box and connectors may be deteri-
orated or damaged.
