Danger of death from electric shock!
Solar modules generate electricity as soon as they are exposed
to light. One module on its own is below the safety extra low
volt level, but multiple modules connected in series (summing
the voltage) or in parallel (summing the current) represent a
danger. The following points must be observed when handling
the solar modules to avoid the risk of re, sparking and fatal
electric shock.
• Do not insert electrically conducting parts into the plugs
or sockets!
• Do not t solar modules and wiring with wet plugs and
sockets
• Exercise utmost caution when carrying out work on wiring
and safety equipment (use insulated tools, insulated gloves,
etc.)
• Do not use damaged modules!
• Do not dismantle modules!
• Do not mark on the rear of the module using sharp objects!
• Exercise utmost caution when working on wiring and the
inverter. Be sure carefully to follow manufacture’s installation
instructions!
Danger of death from arcing
Modules generate direct current when light shines on them.
An arc may be produced when connections are separated.
We therefore recommended covering modules with a lightproof
cloth during installation. When breaking a connected string
of modules (e.g. when disconnecting the DC line from
the inverter under load), a lethally strong arc can occur:
• Never disconnect the solar generator from the inverter
while the inverter is connected to the mains grid - remove
the fuse from the AC side on the inverter rst!
• Ensure cable connections in perfect condition (no splitting,
soiling or other contamination)!
Unpacking the modules and storage
The utmost care is required when handling the modules. Be
careful when unpacking, transporting, and storing the modules:
• Transport modules in an upright position.
• Carry modules with both hands. Do not use the connection
socket as a handle.
• Ensure modules do not bow under their own weight.
• Do not place modules on top of each other.
• Do not subject to load, do not stand on them.
• Do not mark using sharp implements.
• Keep all electrical contacts clean and dry.
If it is necessary to store the modules temporarily, a dry,
ventilated room should be used.
General safety information
Ensure that the module is used only in applications for which
it is suitable (see “Installing the modules”). All work on a PV sys-
tem (installation, setup, maintenance, repairs) must be carried
out only by appropriately qualied and authorized persons.
The appropriate DIN standards, construction rules and safety
instructions are to be followed for installation.
Installing the modules
When installing the modules, please pay
attention to:
Keeping within the maximum permitted load
The maximum load on the module must not exceed 2.4kN/
m2.To avoid exceeding the maximum load, site-specic live
loads such as wind and snow should taken into account.
Environmental conditions
The module is intended for use in temperate climatic conditions.
The module is “non-explosion-protected equipment”. Hence it
must not be installed in the proximity of highly inammable
gases and vapours (e.g. lling stations, gas containers,
paint equipment). The module must not be installed near to
naked ames or ammable materials. Do not expose modules
to concentrated light sources. It must not be immersed in water
or constantly exposed to water (e.g. from fountains). If there is
exposure to salt (it is recommended that modules are installed
at least 500m from the sea) and sulphur (sulphur sources,
volcanoes), there is a risk of corrosion.
Requirements of installation
Make sure the modules’ electrical performances in a system
are the same. When connected in series, modules must all have
the same amperage. When connected in parallel, the modules
must all have the same voltage. Connect the quantity of modules
that match the voltage specications of the devices used
in the system. The modules must not be connected together to
create a voltage higher than the permitted system voltage.
To minimize risk in the event of an indirect lightning strike avoid
forming loops when designing the system. Modules must not
be tted as overhead glazing. Ensure that the mounting system
can also withstand the anticipated wind and snow loads. Precipi-
tation can run off through small openings on the back side
of the module. Make sure that the openings are not masked
after mounting.
Optimum orientation and tilt
To achieve the maximum annual yield gure out what the optimum
orientation and tilt of the PV modules is. If sunlight shines
vertical onto the PV modules you have the best conditions to
generate maximum power.
Avoid overshadowing
Even the slightest partial shading (e.g. from dirt deposits) will
cause a reduction in yield. A module is considered “shadowfree”
if it is unobscured across its entire surface for the whole
year and even on the shortest day of the year unobstructed
sunlight can reach the module.
Reliable ventilation
Functioning ventilation prevents the build-up of heat, which
would reduce performance.
Carefully read through these installation instructions before installing, operating or servicing PV
system. Failure to follow these instructions may result in bodily injury or damage to property.
Keep these instructions! Working on a PV system (installation, setup, maintenance, repairs)
must be carried out by qualied and authorized persons.
Installation guide

Earthing
Although the modules are certied to safety class II, we still
recommend
earthing them. The earth connection must be made
by a qualied electrician.
Option 1:
Connect module frames to each other using cables with cable
lugs. Use the hole (M4mm) that are provided for this purpose.
To create the conductive connection (frame is anodized), use
a serrated washer or a self-tapping screw (3.5mm). The earth
connection should be made by a qualied electrician.
Option 2:
Create an electrical connection between the frames and the
mounting system, e.g. by using serrated washer, then have
the mounting system earthed by a qualied electrician. (See
“Mounting” example A)
Do not interrupt or inuence the conductive connection when
making daily maintenance.
All the crunodes on the conductive connection must be xed.
The fastness does not depend on soldering.
The metal containing iron in the conductive connection should
be handled by some way, such as anodization, spray-painting,
galvanization. Stainless steel does not need to be treated.
Mounting
Each module must be securely fastened at a minimum of
6 points.The frame has been stress tested for mounting on the
long sides.
Example for mounting the PV modules
to the substructure:

4.- Aluminum clamping plate
5.- EPDM washer 2mm
We recommend using a torque wrench for installation. In example
B, the tightening torque (using stainless steel M8 bolts) should be
around 15-20Nm.Use the existing holes for securing the module
and do not drill additional holes (doing so would void the warran-
ty). Use appropriate corrosion-proof fastening materials.
Wiring
For the wiring, pay attention to:
Correct wiring scheme
When designing the system, avoid forming loops (to minimize
risk in the event of an indirect lighting strike). Check that wiring
is correct before starting up the generator. If the measured open
circuit voltage (Uoc) and short-circuit current (Isc) differ from the
specications, then there is a wiring fault.
Correct connection of multi-contact (MC) plug connectors
The plug connector has its own polarity. Make sure that the
connection is safe and tight. The plug connector should not
receive outer stress. Otherwise, it is only used to connect the
circuit!
Use of suitable materials
Use cable extensions and plugs that are designed for outdoor
applications. Ensure that they are in perfect electrical and mecha-
nical condition. Use only cables having one conductor. Select the
appropriate cable diameter to minimize voltage drop (to calculate
the minimum cable diameter, the fuse, and to calculate controls,
multiply the Isc and Uoc by a factor of 1.25).
Maintenance and cleaning
Do not change the PV components optionally (diode, junction
box, plug connectors ). Given a sufcient tilt (at least 15°), it is
not generally necessary to clean the modules (rainfall will have a
self-cleaning effect). In case of heavy soiling (which will result in
output reductions), we recommend cleaning the modules using
plenty of water (from a hose) without cleaning agents and using a
gentle cleaning implement (a sponge). Dirt must never be scraped
or rubbed away when dry, as this will cause microscratched.
We recommend that the system be inspected at
regular intervals.
Checklists:
• All fastenings are tight and secure and free of corrosion.

• Cables are not damaged in any way.
• Checking the earthing resistivity of metals.

MOUNTING INSTRUCTIONS
Standard modules
For a clear understanding of our modules, please refer to the
illustration of a standard module shown below:
1. Grounding holes
2. Junction box
3. Standard mounting holes (long side)
4. Additional mounting holes
5. (high wind or snow loads)
6. Standard mounting holes (short side)
7. Module frame
8. Cables and connectors
• The mounting design must be certied by a registered profes-
sional engineer. The mounting design and procedures must
comply with local codes and requirements from all relevant
authorities.
• Exiom Solution Inc. does not provide mounting hardware.
• Standard modules can be mounted onto a support structure
using one of several approved methods. One such method is
described below. For details of other mounting methods and
the methods recommended by Exiom Solution Inc. for special
module ranges, please refer to our Installation Manual Annex
(Section Annex A: Alternative Mounting Methods) on our we-
bsite (www.exiomsolution.com). For information about other
installation hardware, please contact your local representa-
tive. Failure to use a recognized installation method will void
the Exiom Solution Inc. warranty.
• Use appropriate corrosion-proof fastening materials.
• All mounting hardware (bolts, spring washers, at washers,
nuts) should be stainless steel.
• Use a torque wrench for installation.
• Do not drill additional holes or modify the module frame.
Doing so will void the warranty.
• Standard modules can be installed in either landscape or por-
trait orientations. Refer to the detailed instructions for further
guidance. Please note that in areas with heavy snowfall (>
2400 Pa) further countermeasures such as the use of addi-
tional support bars should be considered to avoid snow loads
damaging the lowest row of modules.
• In cases where an additional support bar is recommended to
improve both mechanical stability and long-term module per-
formance, Exiom Solution recommends selecting sufciently
resistant material. Exiom Solution Inc. recommends bars with
a minimum thickness of 50 mm (1.97 in). The support bar
centerline should be positioned within 100 mm (3.94 in) of
the side frame centerline (slight shifts may be necessary to
access module grounding holes).
MOUNTING METHOD:
BOLT ING
• The mounting method has been qualied by Exiom Solution
Inc. and certied by VDE. Modules should be bolted to sup-
port structures through the mounting holes in the rear frame
anges only.
• Each module must be securely fastened at a minimum of 4
points on two opposite sides M6X1-Grade8.8 bolt and nut
are used for bolting method (exception: M8X1.25-Grade8.8
bolt and nut are used for CS6U and CS6K series modules).
Tightening torques should be within 6~12 Nm (4.4-8.9 ft-lbs)
and (17~23) Nm (12.5~17.0 ft-lbs) respectively for M6 and
M8 coarse thread bolts, depending on bolt class. In areas
with heavy wind loads, additional mounting points should be
used. The system designer and the installer are responsible
for calculating the load and ensuring that the support structu-
re meets the requirements.
• Design load and safety factors will be determined by the
racking suppliers or professional engineers.
For detailed information, please follow local structural code or
contact your professional structural engineer.
