The use of the modules relates to class A: dangerous voltage (IEC 61730: higher than 50V
DC, EN 61730: higher than 120V), dangerous power applications (higher than 240W) which
are general accessible, according to EN IEC 61730 -1 and -2. Protection class II regulations
are also fulfilled.
Maximum reverse over current verified according to IEC 61730 -2, MST 26 of the module:
15A.
The Current rating of the diodes is 16A according to the manufacturer's specifications. Under
open field conditions, photovoltaic modules can produce voltages and/or currents that are
higher than specified on the nameplate. To consider this in the rating dimensioning of other
system components (e.g. electrical lines, electrical fuse, …) that are directly connected to the
PV generator, the Isc and Uoc values should be multiplied by the safety factor 1.25 or
designed by a specialist.
The permissible ambient temperature range for operation and storage is -40 ° C to + 85 ° C.
Safety and installation instructions for mounting
Consider general health and safety regulations relating to mounting equipment on roofs
and/or buildings. Secure the modules, so that they cannot fall down during mounting and in
further operation. Take care and consider the wind and snow load figures for the affected area.
In addition, observe the following:
Electrically
The following should provide a basis to avoid fire, formation of sparks and deadly electrical shock;
Therefore, they have to be followed stringently. Remember, in de –energized state, high contact
voltage could occur and / or deadly electric arc can be generated. Cover the single module with a
lightproof material during the mounting process.
Modules generate electricity as soon as they are exposed to any kind of light. This is unrelated to
whether the module has already been connected or not. So voltage may occur which can be fatal in
some circumstances!
Never install damaged photovoltaic modules.
Never touch cable heads (especially exposed ones) during the mounting, especially when the
module is exposed to light or sunlight.
The tools used for mounting should be approved, isolated and voltage proofed (according to
system voltage).
Do not bring electrically conducting parts (not isolated tools, jewellery or others) in contact with
the photovoltaic module, the cable heads or the electrical plugs during the mounting.
Conductive objects include uninsulated tools, jewelry or other conductive materials.
In case of a roof mounting, additional installations like fuses, DC disconnectors, earth fault
detection etc. may be necessary. In this case, please contact the appropriate specialists
before installation.
Never use the photovoltaic modules near or in rooms, where flammable liquids or gases are
stored or where theses liquids or gases could escape.
When modules are connected in serial, only modules with the same current should be used.
When you are using a parallel connection, only modules with the same voltage should be
used. Never operate the modules with a higher voltage than the maximum system voltage.
The maximum allowed number of modules used in a serial connection is an outcome of the
maximum input voltage / maximum input current of the used inverters / charge regulators, the

KIOTO_Installation_manual_2021 © KIOTO Photovoltaics GmbH, Solarstraße 1, 9300 Sankt Veit/Glan - Österreich 06/2021
used module type and the local temperature conditions. The maximum system voltage must
not be exceeded!
The maximum reverse over current is 15A. When connecting more than two strings in parallel
this value could be exceeded. Therefore, string fuses with a rating of maximum 15A have to
be installed.
Only modules with the same configuration may be used within a system.
Mechanically
Mounting works must be done when the environment and tools are dry.
Clean gloves must be worn while any transport and installation work to avoid soiling of the
solar glass, which is equipped with a special anti-reflection coating.
Make sure that the module meets the system compatibility and the requirements of the
mounting system and that the system compatibility is given.
No sharp objects may be mounted under the module, as the module could bend under load.
The first row of modules must be secured against slipping with safety hooks.
Do not use the junction box as a handle.
Consider local factors for example wind force, wind speed and snow load. Calculate these
values with a security factor, before mounting the modules. In special cases, a static
calculation must be undertaken. KIOTO modules are designed and tested to resist a suction
force (e.g. wind) of maximum 2400 Pa and a static pressure force/load (e.g. snow) of
maximum 5400 Pa, provided that they are mounted according to the specified points of
application.
Ensure that there is adequate ventilation behind the modules.
To generate optimal output of the photovoltaic generator, consider the perfect alignment and
mounting angle of the photovoltaic modules.
Shadowing of the modules leads to loss of output. Therefore, take care that there is no
shadowing on the photovoltaic array over the whole year.
Never mount KIOTO modules in areas where abnormal (aggressive) conditions can occur.
If modules are installed on farm buildings, the products shall not be used as a roof
replacement. A minimum distance of 1,5 m to roof and ventilations openings has to be
observed.
When the modules are mounted on-roof, ensure that the roofs are fire resistant or that an
appropriate fire protection layer, designed for this use, is installed. In case of fire, never
extinguish with water! Inappropriate installation could also lead to hazard in case of fire.
Incorrect installation can lead to a fire hazard.
The PV –module is an equipment which is not protected against explosion. Therefore, the
modules must not be installed near flammable gases and liquids (e.g. gasoline stations, gas
tanks, colour spraying plants etc.).
The PV module must not be installed next to naked flames and flammable materials.
Unless explicitly marked, the PV module is not a laminated safety glass (LSG) component.
Please also observe all safety instructions of the other components used.
Make sure that other mechanical system components cannot have a harmful effect on the
modules.
Advices double glass modules without frame
KIOTO double glass modules are containing bifacial cells that allow a higher yield through
reflection on the bottom side. If possible, make sure to minimize shading on the backside.

Any technical advice in verbal or written form or in any other way, is given on the basis of the
actual knowledge, but without any warranty and / or liability.
A project-related, static dimensioning and the glass-technically correct use of the glasses is
not carried out or checked by us. This is the responsibility of the system installer.
Special technical designs or special constructions may be subject to official approval. It is the
responsibility of the customer or the building owner to obtain such approval. Resulting
changes in design or additional services, in particular tests and calculation proofs, are at the
expense of the customer.
Fixing points of the KIOTO modules
Detailed information about the mounting (clamping range) and the load limits can be found in
the following file: "KIOTO_Mounting_matrix_2021".
To resist the named snow and wind loads, the marked distances must be followed when mounting. In
case of a longitudinal mounting, the specified mounting points must also be adhered to. If this is not
possible because of the substructure, a crossbar system must be used!
For standard mounting of modules with frame, the modules must be securely fastened with
continuous support profiles at least 4 points.
The PV modules can only be attached to the substructure by clamping from the front. The clamping
area must be at least 400 mm² per fastening point. Use a torque wrench for assembly. The tightening
torque for an M8 screw made of V2A is 20Nm. Use suitable, corrosion-proof fastening material.
When assembling modules without frame, they must be clamped with laminate clamps. The
minimum length for these laminate clamps is 100mm. We generally recommend vertically mounted
laminate modules to be secured against sliding out of the laminate clamps with a slip protection when
clamping on the long module side. The tightening torque of the laminate clamps can be found in the
data sheet of the clamp manufacturer.
Electrical connection of the photovoltaic generator
At high direct current voltages, as canoccur in serial connections, the risk of short circuits andelectric
arcs is higher. Toavoid this, always use an adequatecross sectionfor cables and connectors, which
are approvedfor the maximum specified value of open circuit voltage.

At strong currents, as can occur in parallel connections, therisk of warming of the connections is
higher. To avoid this risk, use an adequate sizing of the cross section.
The solar cables must be approved for the possible maximum short circuit current.
Make sure that other electrical system components may have no adverse effect on the modules.
Detailed information about the connection technique, solar cable and
connectors/plugs
Only use cables and connectors/plugs which are approved and testedfor photovoltaic applications.
The choice of cables for the use in the photovoltaic generator must be based on sizing by a skilled
person. Cables with a cross section from 4mm² to 6mm² are recommended. The optimum cross
section should be determined by the maximum short circuit voltage and the complete length of the
wiring (line voltage drop).
Only use high qualitycables to assure a failure –free operating. Ensure good isolation and
whether/UV-durability of the cables.
The rated voltage of the solar cable must be 1000Vminimum.
If possible, use flexible cables to ensure consistency against movements, wind etc. This will make
the laying of the cables easier (pleasefind detailed information in the next clause).
Only use tools which are approved for cutting, isolating etc. of the cables or employ qualified
persons/staff.
Only use connectors / plugs which are approved and tested for photovoltaic applications.
Only plug in the connectors when dry and clean. Make sure that they are properly connected.
The connector system is fully latched only when the snap arm is fully obvious in the inspection
window. Take care of the clearance.
When disconnecting the connector, open the lock with the opening tool and pull the connector
apart.
For information about the compatible cables, please refer to the respective connector system
manufacturer.
Further information about the plugs/connectors can be found in the manufacturer's documents:
Stäubli Electrical Connectors MC4: MA231
Stäubli Electrical Connectors MC4 EVO2: MA273
Safety note: DO NOT disconnect the plugs/connectors under load! NEVER disconnect when
the system is in operation! Non-compliance is FATAL. You will find the safety note also
printed on the photovoltaic module product label and on the system plugs.

Laying of the solar cables
Keep the length of cable connections as short as possible, to optimize the energy yield and
minimize sources of errors. Consider thispoint while planning and sizing the generator.
Fix loose solar cables after mounting to avoid damaging. Use only adequate fixing material
(conduits in the mounting profiles or UV–resistant plastic tubes).
Take care while handling the cables to avoid damaging, especially at low temperatures.
The cables should not be bent orfolded in an extreme way. Where possible use flexible cables.
Please follow supplier instructions.
Use conduits for laying and fixing of the cables.
To avoid voltagesfrom indirect lightning strikes, lay the feed line and return line very close to each
other.
Always consider the polarity.
The cables must not lie between the mounting profiles and module backsidetoavoid damaging the
module, especially under heavy mechanical load.
Electrical connection
The modules must be covered with a light resistant material during the complete mounting process.
Avoid damaging the module and those cables.
Execute the system grounding according to national and international standards.
Sizing of inverters should be done upfront. The installation has to be done byqualified persons to
ensure an optimized energy yield.
For safety reasonsand to minimize maintenance works, a DC disconnector should be installed
between the generator and the inverter. This could also be obligatory by law.
Connection of the module to a grounding system
The photovoltaic modules can be grounded as follows:
Modul series
Possibility to connect the grounding to the frame
Power-60
Power-MAXIM
On the bottom side of the module frame, in the areaof the plastic
corner connector
- Earthing sign on the corner connector
Power-ALPIN
Glas-60 framed
Project-60
Project-60 halfcut
On the bottom side of the module frame
- Earthing sign on the frame
The adequately sized grounding cable must be connected with a stainless steel (A2) ISO 7981
screw (3,9x 6,5mm) with a form C rounded head with two fan shaped washers (on the outside and
inside of the eyelet).The assembly from the outside to the inside should be: screw head –fan
shaped washer –eyelet –fan shaped washer –frame.
For the professional grounding of the complete photovoltaic system the installer is responsible. If a
grounding system is already in use at the affected building, the photovoltaicgenerator has to be
integrated in this protection system against direct lightning strikes. National standards have to be
considered and executed.
The modules must be earthed through the provided holes on the frame of the module or in a proper
manner through other electrically conductive materials, such as the supporting structure. This may
only be performed by aqualified specialist.

Commissioning of the photovoltaic power plant
Before initiation of thegenerator, please check all components (observe the installation instructions of other
components), the electrical connection and all plugs, that they are connected correctly and ensure that the
connection is tight.
Solar generators with a direct current voltage from more than 50V must be installed/initiated
by qualified persons!
The open circuit voltage of every serial connection should be checked after initiation. Follow the rule: Result
of the measurement = sum of the open circuit voltages of the single modules. Considerthe actual time, sun
irradiation, shadowing and other factors while measuring the open circuit voltage, otherwise the result of the
sum and the single results could deviate considerably.
Maintenance
Soiling on the module surface can lead to a reduction in performance.
Clean the modules as required and soiled with plenty of water and a soft cloth or sponge without
any detergent. Do not use high pressure cleaners!
If other additives or devices like aggressive chemicals, scrubbing agents, sharp blades or steel
wool are used the guarantee and product warranty will be invalid! Never wipe off or scrape off
pollution in a dry state of the module surface.
An additional application of water / dirt resistant coatings can affect the efficiency of the modules
and also the yield, in a negative way.
Check the module wiring and the singlemodule plugs to ensure they are clean, corrosion free,
mechanically ok and tight in regular intervals.
ATTENTION: Never disconnect the plugs under load!
Free themodules, if necessary,from high snow loads.
Check the substructure in regular intervals for their tightness.
Never try to open or repair parts of the module or of the junction box on your own.
All other trouble shootings, repairing andmaintenance works must be done by qualified, skilled
staff/persons.
For further information relating to warranties etc. please read through the GENERAL TERMS
AND CONDITIONS of KIOTO Photovoltaics GmbH.
