Safety Precautions; Warning; Cautions - Panasonic VBHNxxxSJ25 series Installation Manual

SAFETY PRECAUTIONS

•
All instructions should be read and understood
before attempting to install, wire, operate, and
maintain the module.
•
The installation of modules requires a great
degree of skill and should only be performed by
qualified licensed professionals, including,
without limitation, licensed contractors and
licensed electricians.
•
The installer assumes the risk of all injury that
might occur during installation, including,
without limitation, the risk of electric shock.
•
Before installing modules, contact the appropri-
ate 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.
•
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.
•
For a non-integrated module, the assembly is
to be mounted over a fire resistant roof cover-
ing rated for the application.
•
For modules mounted on roofs, special con-
struction or structures may be required to help
provide proper installation support.
•
Do not install the module where flammable
gases or vapors are present.
•
Do not use modules of different specifications
in the same system.
•
Follow all safety precautions of other system
components used.
•
In some areas, local electrical codes may gov-
ern the installation and use of modules.

WARNING

To avoid the hazard of electric shock, sparks, fire and
injury
•
The modules generate DC electrical energy
when exposed to sunlight or other light
sources, so cover the entire front surface of the
modules with a dense, opaque material such as
a cardboard box, during installation 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
maximum 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 conditions, with dry modules
and dry tools.
•
Children and unauthorized persons should not
be allowed near the installation 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 conductive parts.
•
Do not disassemble the module, or remove any
parts installed by the manufacturer.
•
Do not open a junction box's lid.
•
Do not touch the junction 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
compatible, and they do not subject the mod-
ule to mechanical or electrical hazards.
•
Do not artificially 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 junction
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, attempt
any repair, open the junction box cover, nor
remove any parts installed by Panasonic.
There are no user serviceable parts within the
module or junction box.
•
Do not treat the back sheet or front surface
with paint or adhesives.
•
Do not use or install broken modules. If you
find 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.
