Samsung PV-MBA1BG 244 Installation Instructions Manual page 11

1 - Pressure Clamps or Clips:
Mount the module with the clips on the side frame
of the module. The side frames are attached to the
longer sides of the module. Installers should ensure
the clamps are of sufficient strength to allow for the
maximum design pressure of the module. Please follow
mounting guideline (page 7).
the metal clamp must fulfill the following
specifications:
Size (width) Thickness of
material
not less than not less than
1.5" (38 mm) 0.12" (3 mm)
2 - Frame Holes:
Secure the module to the structure using the factory
mounting holes (Figure 3). Four 1/4" stainless steel
bolts, with nuts washers and lock washers are to be
mounted per module.
ELECTRICAL INSTALLATION
• Under certain conditions, a photovoltaic module may
experience conditions that produce more current and/
or voltage than reported at standard test conditions.
Accordingly, the values of ISC and VOC marked on this
module should be multiplied by a factor of 1.25 when
determining component voltage ratings, conductor
ampacities, fuse sizes, and size of controls connected
to the PV output. (UL)
• Refer to Section 690-8 of the National Electrical Code
for an additional multiplying factor of 125 percent (80
percent derating) which may be applicable.
• The modules should not be configured in such way
that they create a voltage higher than the permitted
system voltage.
wiring
GENERAL
• All wiring should be done in accordance with
applicable electrical codes.
• A qualified, licensed professional should do all wiring.
• 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.
MODULE WIRING
• Check local temperature conditions and follow the
National Electric Code (eg. NEC 690.7 for USA, DIN
VDE 0100 Teil 712 for Germany) to ensure compliance
with maximum voltage limitations.
• Modules are not designed for "off-grid" or battery
charging systems, because of their operating voltage.
Therefore, it is not recommended to use them to
charge batteries.
• These modules contain factory installed bypass
diodes. If these modules are incorrectly connected to
each other, the bypass diodes, cable, or junction box
may be damaged.
Rev. 12
• National electrical codes and regulations should be
strictly followed.
• PV Modules may be connected in series or parallel to
achieve the desired electrical output as long as certain
conditions are met. Use only the same type of modules
in a combined source circuit.
• If the modules are to be connected together in series
they should have the same amperage.
• If they are to be connected in parallel they should
have the same voltage. String configuration should be
planned and carried out in accordance with inverter
Material
manufacturer's instructions.
• The number of modules connected to an inverter
Stainless steel should be within the inverter voltage limits/operating
aluminum range and the design of the string configuration(s)
should comply with the inverter manufacturer's
guidelines.
• Blocking diodes prevent current flowing from the
battery to the module when no electricity is being
generated. It is recommended to use blocking diodes
when a charging regulator is not used.
• When installing the modules, keep attention that the
voltage of parallel connection should not exceed
maximum system voltage.
OPERATING CONDITIONS
All Samsung modules require that modules be operated
within the following Operating Conditions:
1. Terrestrial applications only – no outer space or Special
Conditions (see below).
2. The ambient temperature must be within -20 °C (-4 °F)
to +60 °C (140 °F).
3. The wind pressure load of the installation site should
be less than or equal to 2400 Pascal.
4. Some environmental conditions could apply. Please
refer to Samsung's warranty exclusions.
ARRAY WIRING
• The term "array" is used to describe the assembly
of several modules on a support structure with
associated wiring.
• Samsung recommends that all wiring be double-
insulated with a minimum rating of 90 °C (194 °F). All
wiring should use flexible copper (Cu) conductors. The
minimum size should be determined by the applicable
codes.
• PV Modules may be wired in series to produce the
desired voltage output. Do not exceed the maximum
system voltage.
• PV Modules may be wired in parallel to produce the
desired current output. Refer to the applicable regional
and local codes for additional fusing requirements and
limitations on the maximum number of PV Modules in
parallel.
MODULE TERMINATIONS
• A junction box as a terminal enclosure is equipped for
electrical connections.
