Application class of product
SANYO HIT PV-modules are applied to
application class A. Application class A for
PV-modules are defined as follows:
Class A: General access, hazardous
voltage, hazardous power applications
Module rated for use in this application
class may be used in systems operating at
greater than 50 V DC or 240 W, where
general contact access is anticipated.
Modules qualified for safety through this
part of IEC 61730-1 and IEC 61730-2 and
within
this
application
considered to meet the requirements for
safety class II.
Fire class of product
Sanyo HIT PV modules fill the fire class C
that provides to ANSI/UL790. Class C roof
coverings are effective against light fire
test exposures. Under such exposures,
roof coverings of this class afford a light
degree of fire protection to the roof deck,
do not slip from position, and are not
expected to produce flying brands.

CERTIFICATION
The HIT-HxxxE01, HIT-HxxxE02 Modules
comply with the requirements of IEC61215,
IEC61730-1, IEC61730-2 and the CE
mark.
WIRING
General
•
All
wiring
should
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
connect electrical load to avoid the
is
hazard of electrical shock.
•
Test
To avoid the hazard of electric shock
and sparks, please connect each
cable after confirming the polarity of
them is correct.
•
Cable conduits should be used in
locations
inaccessible to children or small
animals.
Module Wiring
•
The maximum number of H-type
modules that can be wired in series is
twenty (20).
•
Modules shall not be wired in parallel
without
protection.
•
When installing a PV array, the

Array Wiring
•
The term "array" is used to describe
the assembly of several modules on a
support structure with associated
wiring.
•

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 non-
conductive coatings, such as paint,
anodized coatings or vitreous enamel.

improper connection.
•
Please
contact
your
Authorized
Representative
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
2
conduit is 4.0 mm
.
•
Verify that all fittings are properly
installed to protect wires against
damage
and
prevent
intrusion.
DIODES
Bypass Diodes
•
When the modules in series strings
are shaded partially, it may cause
reverse
voltage
across
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
systems within the specified system
voltage, so that you do not need any
other additional bypass diodes.
•
Specifications of bypass diode for
