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-NxxxE01, HIT-NxxxE02 Modules
comply with the requirements of IEC61215,
IEC61730-1,
IEC61730-2 and the CE
mark.
WIRING
General
All

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

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

Verify that all fittings are properly

installed to protect wires against

and
prevent
intrusion.
DIODES
Bypass Diodes
When the modules in series strings
•
are shaded partially, it may cause
reverse
voltage
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

protection
systems within the specified system
voltage, so that you do not need any
other additional bypass diodes.

diodes due to system specifications.
MAINTENANCE
Some maintenance is recommended

to
maintain
performance of the solar modules.
If the module surface becomes dirty,

it may reduce output power.
It is recommended to clean the
