2. APPLICATIONS

KDxxxGX-LPB modules are a reliable, virtually
maintenance-free direct current (DC) power source,
designed to operate at the highest level of efficiency.
KDxxxGX-LPB modules are ideal for remote home,
water pumping, utility-tied, telecommunications and
many other applications.

3. WARNINGS & SAFETY

PV modules generate electricity when exposed to light.
Arrays of many modules can cause lethal shock and
burn hazards. Only authorized and trained personnel
should have access to these modules. To reduce the risk
of electrical shock or burns, modules may be covered
with an opaque material during installation. Do not touch
live terminals with bare hands. Use insulated tools for
electrical connections. Do not use these modules for
solar concentration.

PERMIT

・

Before installing your PV system, contact local
authorities to determine the necessary permits,
installation and inspection requirements.

INSTALLATION AND OPERATION

・ Systems should be installed by qualified personnel only.

The system involves electricity, and can be dangerous if
the personnel are not familiar with the appropriate safety
procedures.

・ Do not step on the module.
・ Although

KDxxxGX-LPB

modules are quite durable, the
glass can be broken (and the module will no longer work
properly) if it is dropped or hit by tools or other objects.

・ The module frame is made of anodized aluminum, and

therefore corrosion can occur if the module is subject to
a salt-water environment and is in contact with another
type of metal (electrolytic corrosion). If required, PVC or
stainless steel washers can be placed between PV
module frame and support structure to prevent this type
of corrosion.

・ KDxxxGX-LPB

module frame(s) must be attached to a
support structure by one of the methods described in
Section 6, Installing

KDxxxGX-LPB

modules.

・

Module support structures to be used to support

KDxxxGX-LPB

module(s) should be wind rated and
approved by the appropriate local and civil codes prior
to installation.

・

Do not expose the back of the module to direct sunlight

・ In Canada installation shall be in accordance with CSA

C22.1, Safety Standard for Electrical Installations,
Canadian Electrical Code, Part 1.

FIRE RATING

・

In case of roof installation, PV module assembly shall be
mounted on a fire resistant roof covering rated for the
application.

KDxxxGX-LPB

modules are comprised of a
glass front surface, polyethylene terephthalate (PET)
backsheet with a Class C fire rating.

GROUNDING

・

Refer to “Grounding” section.

4. SITE SELECTION

In most applications,

KDxxxGX-LPB

modules should be
installed in a location where they will receive maximum
sunlight throughout the year. In the Northern Hemisphere,
the modules should typically face south, and in the
Southern Hemisphere, the modules should typically face
north. Modules facing 30 degrees away from true South (or
North) will lose approximately 10 to 15 percent of their
power output. If the module faces 60 degrees away from
true South (or North), the power loss will be 20 to 30 percent.
When choosing a site, avoid trees, buildings or obstructions,
which could cast shadows on PV modules especially during
the winter season when the arc of the sun is lowest over the
horizon.

5. MODULE TILT ANGLE

KDxxxGX-LPB

modules produce bigger power when they
are pointed directly at the sun. For grid tie installations
where the PV modules are attached to a permanent
structure, PV modules should be tilted at an angle equal to
the site's latitude. This will typically result in the highest
annual energy output.

6. INSTALLING KDxxxGX-LPB MODULES

To install the module, use bolt and nut on installation holes
which are opened in the module frame and install the
module by following the instruction below.

KD225GX-LPB～～～～KD235GX-LPB

All manuals and user guides at all-guides.com

The minimum spacing of .6” (15 mm) is required between
PV module and the mounting surface around the perimeter
of PV module.

KDxxxGX-LPB

modules may be installed in

various applications utilizing a variety of support structure
options and attachment methods. For optimal performance
in all applications, clearance between the module frame
and the mounting surface is required to allow cooler
ambient air to circulate around the back of the module and
to avoid the module and / or wiring damage. A minimum
of .13” (3.2 mm) spacing must also be maintained between
module frames to allow for thermal expansion.

KDxxxGX-LPB

modules may be attached to a support
structure by the following methods. When installing
modules in snowy area, an appropriate countermeasure
has to be taken to prevent possible damages to the lower
side frame by slipping snow (e.g. attach supporting parts to
the lowest modules.).Any damage caused by snow or such
countermeasure is not covered under warranty.

BOLTING: Utilizing 5/16” or 8 mm steel hardware structure
through the existing .35” (9 mm) diameter mounting holes in
the module frame and then through

KDxxxGX-LPB

modules mounting holes on the support structure. Tighten
the screws with adequate torque (usually 132 in-lb).
Support structure should have enough strength to keep the
mounting span. Refer to the Module Drawings for the
position of PV module mounting holes.

7. MODULE WIRING

KDxxxGX-LPB

modules come pre-wired with terminals
ready for most building attachments or free standing
installations. Each module has two #12 AWG type USE-2/
PV-wire stranded sunlight resistant output cables each
terminated with Multi-Contact



locking connectors. The
positive (+) terminal has a male connector while the
negative (-) terminal has a female connector. The module
wiring is solely for series connections only, i.e. male (+) to
female (-) interconnections. Series and parallel connections
shall be made by use of two #10-14 AWG type USE-2/
PV-wire stranded sunlight resistant output cables with male
and female Multi-Contact



locking connectors.

NOTE

: When making connections with Multi-Contact
connectors, make sure the array is disabled. DO NOT
MAKE CONNECTIONS WHILE UNDER LOAD. Module
output connections are marked “Do not disconnect under
load”.
NOTE: MAXIMUM SYSTEM VOLTAGE 600 VDC.

KDxxxGX-LPB

modules and most PV system components
have a maximum system voltage rating of 600 volts DC.
Some grid feed in systems operate at or near this voltage
rating. Like other polycrystalline solar modules, the open
circuit voltage of the

KDxxxGX-LPB

modules increases as
the ambient temperature decreases. Maximum system
voltage is computed as the sum of the open-circuit voltage
of the series-connected PV modules for the lowest
expected ambient temperature. Refer to the National
Electrical Code Article 690-7(a) for determining the
maximum number of

KDxxxGX-LPB

modules that can be

placed

in series. Temperature coefficients, specific to the
module of use, can be used to provide the most accurate
prediction of module voltage under temperature extremes.

NOTE

: Install the maximum number of series connection for

the

KDxxxGX-LPB

modules so that the system voltage is
less than 600 V.
NOTE

: Do not connect the modules in parallel without
maximum over current protection.
NOTE

: The minimum diameter that the cable can be bent
for the

KDxxxGX-LPB

modules is 1.93” (49mm).

NOTE

: In normal conditions, PV modules may produce
larger current and/or voltage than reported in the standard
test conditions. Therefore, when voltage evaluations for
components, capacity of conductors, size of fuses, and size
of control systems connected to the module output are
determined, multiply the values of short- circuit current (Isc)
and open-circuit voltage (Voc) that are marked in

KDxxxGX-LPB

modules by the coefficient, 1.25.

8. GROUNDING

Before installation, contact the local code authorities to
determine the necessary grounding requirements. When
installing in US market, attach all PV module frames to an
earth ground in accordance with the National Electrical
Code (NEC) Article 250. Proper grounding is achieved by
connecting PV module frames and all metallic structural
members contiguously to one another using a suitable
grounding conductor. The grounding conductor shall be of
copper, copper alloy or another material suitable for use as
an electrical conductor per NEC. The grounding conductor
must then make a connection to earth using a suitable earth
grounding electrode. Ensure positive electrical contact
through the anodizing on the module frame extrusion by
utilizing one of the following methods. Attach the grounding
conductor:
(1)to one of the .35” (9mm) diameter holes marked “ground”

using 5/16” stainless steel hardware. Wrap conductor
around bolt. Tighten the screws with adequate torque
(usually 132 in-lb). Avoid direct contact of copper ground
conductor to aluminum frame.

(2)to a ground lug (manufacturer:ILSCO,model:GBL-4DBT).

Tighten the screws with adequate torque (usually 62
in-lb). Use #10-32 stainless steel hardware to attach the
lug to the module frame by the torque of 40 in-lb. A
stainless steel star washer, positioned between the lug
and the anodized surface of the frame, must be employed
to break through the anodized layer of the frame
extrusion and electrically connect the ground lug to the

conducting aluminum frame material.
As a general rule, avoid direct contact of copper or copper
alloyed ground conductors with the aluminum module frame.
All ground bond securing hardware in contact with either the
aluminum module frame and/ or copper or copper alloy
ground conductors must be stainless steel.
