1. Product ldentification
Each module has three labels providing the following information:
1. Nameplate: describes the product type: Peak power, Max. power current, Max. power voltage, open circuit voltage, short circuit
current, all as measured understandard test conditions; Certifications mark,the maximum system voltge etc.
2.
Current Sorting: Modules are sorted out according to their Max. powercurrent, referred as a corresponding symbol "Current class
X" attached, in which x takes the value H, M or
L(H
marks physically the highest current).
To
get optimal performance out of a string
of
Modules it is recommended to connect only Modules
of
the sama "Current class X" class (for example only H Modules)
in
one given
string.We recommend the modules with
and
without
LRF
should notbe installed in a inverter, even
if
they are the same currentclass. For
the rest
of
modules with differentcurrent classes, the modules with adjacent current class can be installed in onegiven string.
3.
Serial number: each individual module has a unique serial number. The serial number has 16 digits. The 1stand the 2nd digits are
the year code,
and
the 3th is the month code {A,
B,
e stands for October, November and December respectively). For example,
121XXXXXXXXXXXXXmeans the module was assembled and testad
in
the January
of
2012. Each module has only one barcode.
lt
is
permanentlyattached
to
theinterior
of
the module and is visible from the
1Dp
front ofthe module. This barcode
is
insertad priortolaminating. 1n
addition, you can find the same barcode beside the nameplate.
2. Conventional Safety
JASolar Modules are designad to meet the requirements
of
IEC 61215 and IEC 61730, application classA. Modules rated for use in
this application class may be used
in
system operating at greater than 50V DC
or
240W, where general contact access is anticipated.
Modules qualified forsafetythrough I
EC
61730-1
and IEC 61730-2
and
within this application classareconsidered
to
meetthe requirements
for safety class
II
equipment.
When Modules are mounted on rooltops, the roofmusthave a fire resistant covering suitableforthis application. Rooltop PVsystems
should only
be
installed on rooftops capable ofhandling the additional weighted load
of
PVsystem components, including Modules, and
have a complete analysis ofthe structure performed by a certified building specialist
or
engineer.
Foryoursafety,
do
notattempttoworkon a rooftop until safetyprecautions have been identified
and
taken, includingwithout limitation:
fall protection measures, ladders or stairways, and personal protective equipment.
For your safety, do not instan or handle Modules underadverse conditions, including without limitation strong or gusty winds, and wet
or
frosted roofsurfaces.
3. Electrical Performance Safety
Pho1Dvoltaic
Modules can produce DC electricity when exposed to light and therefore can produce
an
electrical shock
or
burn. DC
voltage of30 Volts or higher is potentially lethal.
Modules produce voltageeven when not connected
to
an
electrical circuit
or
load. Please use insulatedtools and electricallyinsulated
gloves when working with Modules in sunlight.
Modules have no on/off switch. Modules
can
be rendered inoperative only by removing them from sunlight, or byfully covering their
front surfacewith cloth, cardboard,
or
other completely opaque material, or byworking with Modules face down
on
a smooth, flat surface.
In order to avoid ares and electrical shock, please do notdisconnect electrical connections underload. Faulty connections
can
also
result in ares and electrical shock. So pisase keep connectors dryand clean, and ensure thattheyare
in
properworking condition. Nevar
insert metal objects intothe connector,
or
modifythem in anywayin orderto secure an electrical connection.
Also in arder to avoid the sand
or
water vapor entering which may cause a safety issuewith the connection, the modules need
to
be
installed and connected to the combiner box once they are taken outfrom the carton box, keep the connectors dryand clean during the
installation, ifthe modules are not be installed within a week, rubber connectorcovers shall be added as a protective measure. Note that
pollution from sand, dustand waterwill result in ares and electrical shock
of
connectors. We suggest the customers add rubber connector
covers
as
a protection method specific to the area with heavy dust or seaside areas with highersalinity
or
serious polluted areas.
Reflection from snow
or
water can increase sunlight and therefore boost current and power.
In
addition, colder temperaturas
can
substantially increase voltage and power.
lf
the glass or othermaterial is damaged, please wear personal protection equipment and separate the module from the circuit.
No matter howweather condition is, personnel entering the power station shall wear safety helmet, insulating gloves and insulating
shoes correctly, taking self-safety protection measures.
