4 Genaral safety
Follow all permission, installation and inspection re-
quirements.
Before installing modules, contact the appropriate
authorities to determine permissions, installation,
and inspection requirements which should be fol-
lowed.
Electrically ground modules for all systems of any
voltage.
If not otherwise specified, it is recommended that
requirements of the latest National Electrical Code
(USA) or other national or international electrical
standards be used.
Be sure that the construction or structure (roof,
facade, etc.) where the modules are being installed
has enough strength. For modules mounted on roofs,
special construction or structures may be required to
help provide proper installation. Both roof construc-
tion and module installation design have an effect on
the fire resistance of a building. Improper installation
may contribute to fire hazards. Additional devices
such as ground fault, fuses, and disconnects may be
required.
Do not use modules of different specifications in the
same system.
Follow all safety precautions of other system compo-
nents used.
To satisfy regulatory requirements, when installing the
modules, be sure to:
1. Use only stranded or solid copper single-conductor
type UF cable or USE cable rated sunlight resistant,
for modules and modules interconnect wiring that is
exposed to weather.
2. Observe the requirements described in sections
labeled INSTALLATION and SPECIFICATIONS of this
manual.
3. Grounding of the module frame is required. When
ground wires greater than 6 mm
2
(No.10 AWG) are
required, the installer will need to provide suitable
terminal connectors.

Provide suitable guards to prevent contact with
30 VDC or greater. As a Precaution use properly insu-
lated tools only.
Do not damage or scratch the back sheet of the
module.
Do not use the junction box to hold or transport the
module.
Do not drop module or allow objects to fall on mod-
ule.
Do not stand or step on the module.
Do not disassemble, modify or adapt the module or
remove any part or labeling installed by the manu-
facturer.
Do not drill holes in the frame or glass of the mod-
ule.
Do not treat back sheet and front surface of the
module with paint and adhesives.
Do not artificially concentrate light on the module.
Do not wear metallic jewelry while installing or
trouble shooting the module.
Do not change the wiring of bypass diodes.
Do not disconnect modules under load
To help avoid breakage problems
Always transport and store the module in the ship-
ping container provided.
When carrying a module two or more people should
carry it by its frame and wear non-slip gloves (to
avoid injury by a slipping module, to a foot, or cuts by
the edge of a frame, and so on).
Do not leave the module unsupported or unsecured
prior to installation. For example, wind can cause a
module which is leaning against a fence to fall and
break. Avoid application of excessive bending or
twisting forces to the module.
A module with broken glass or torn back-skin cannot
be repaired and must not be used since contact with
any module surface or the frame can produce electri-
cal shock.
Broken or damaged modules must be handled care-
fully and disposed of properly.
Broken glass can be sharp and can cause injury if not
handled with the appropriate protective equipment.
4. Under normal conditions, a photovoltaic module is
likely to 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 capacities, fuse sizes, and size of
controls connected to the PV output.
5. Refer to section 690-8 of the National Electric Code
(NEC) for an additional multiplying factor of 125 %
(80 % de-rating) which may be applicable.
6. Conductor recommendations: single conductor cable,
type USE-2 12 AWG, rated 600 V/1000 V minimum,
90° C minimum, marked sunlight resistant.
5 Installation
General
Please read this guide completely before installation
or use of the modules. This section contains electri-
cal and mechanical specifications needed before
using your Bosch Solar Energy AG PV modules.
Modules should be firmly fixed in place in a manner
suitable to withstand all expected loads, including
wind and snow loads. Module mounting holes are
provided for easy installation and proper mechanical
loading.
Modules should be mounted with the orientation and
tilt angle required for consistent performance (sea-
Important Notice!
sonally, yearly). The location should be selected to
have direct access to sunlight from 9:00a.m. to
3.00p.m. on the shortest day of the year. Calculate
the tilt angle by using the site latitude plus 20 de-
grees, with modules facing south in the northern
latitudes and north in the southern latitudes. This
will result in consistent energy output throughout the
year.
The appropriate material should be used for mount-
ing hardware to prevent the module frame, mounting
structure, and hardware itself from corrosion.
Install modules where they are not shaded by obsta-
cles like buildings and trees.
Especially pay attention to avoid partially shading the
modules by objects during the daytime.
For roof mounted systems, provide adequate rear
ventilation under a module for cooling (100 mm: 4in
gap minimum)
Clearance of 7mm: 0.25” or more between modules
is required to allow for thermal expansion of the
frames.
Observe the specifications for mounting areas ac-
cording to Illustrations 1 and 2.
Attachment with clamps on the narrow sides of the
solar module may not be performed.
The attachment of the solar module can be per-
formed with clamps (or as an alternative, directly on
the installation holes). When clamping systems are
used, the clamp surface per attachment point on the
module must amount to at least 400 mm².
