Safety Precautions; Warning; Cautions - Panasonic HIT VBHN330SA17 General 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 li-
censed professionals, including,
without limitation, licensed contrac-
tors and licensed electricians.

The installer assumes the risk of all
injury that might occur during instal-
lation, including, without limitation,
the risk of electric shock.

Before installing modules, contact
the appropriate authorities to deter-
mine 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 contrib-
ute to fire hazards. Additional de-
vices such as ground fault, fuses,
and disconnects may be required.

For a non-integral module or panel,
the assembly is to be mounted over
a fire resistant roof covering rated
for the application.

For modules mounted on roofs,
special construction or structures
may be required to help provide
proper installation support.

Do not install the module where
flammable gases or vapors are pre-
sent.

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 govern 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 installa-
tion and handling of the modules.

The shock hazard increases as mod-
ules are connected in parallel, pro-
ducing higher current, and as mod-
ules are connected in series, produc-
ing higher voltages.

The shock hazard increases as mod-
ules with nominal open-circuit volt-
age (Voc) in excess of 50 V, and/or
modules rated for maximum system
voltage in excess of 50 V.

Wear suitable clothing, gloves and
guards to prevent from direct con-
tact 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.

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 termi-
nals.

Do not change the wiring of bypass
diodes.

Do not connect or disconnect termi-
nals while modules generate elec-
tricity and connect electrical load.

Never leave a module unsupported
or unsecured.

CAUTIONS

To avoid the hazard of injury, burn and
damage to the module

Use a module for its intended pur-
pose only.

Be sure that all other system compo-
nents are compatible, and they do
not subject the module to mechani-
cal or electrical hazards.

Do not artificially concentrate sun-
light 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 module.

Do not hit the back sheet of a mod-
ule by the connector or other
things.

Do not disassemble a module, at-
tempt 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 mod-
ules.

Do not touch a module unnecessari-
ly. The glass surface and frames get
hot.
