SAFETY PRECAUTIONS
Warning
Before attempting to install, wire, operate
and / or service the module and other
electrical equipment, all instructions should be
read and understood. PV module connectors pass
direct current (DC) when exposed to sunlight or
other light sources. Contact with electrically active
parts of the module, such as terminals, can result in
injury or death, irrespective of whether or not the
module and the other electrical equipment have
been connected.
AVERTISSEMENT:
Toutes les instructions devront être lues
et comprises avant de procéder à l’instal-
lation, le câblage, l’exploitation et/ou l’entretien des
panneaux. Les interconnexions des panneaux con-
duisent du courant continu (CC) lorsque le panneau
est exposé à la lumière du soleil ou à d’autres sources
lumineuses. Tout contact avec des éléments sous ten-
sion du panneau tels que ses bornes de sortie peut
entraîner des blessures ou la mort, que le panneau
soit connecté ou non.
GENERAL SAFETY
· All modules must be installed by licensed electrici-
ans in accordance to the applicable electrical codes
such as, the latest National Electrical Code (USA) or
Canadian Electric Code (Canada) or other national or
international applicable electrical codes.
Protective clothing (non-slip gloves, clo-
thes, etc.) must be worn during installa-
tion to prevent direct contact with 30 V
DC or greater, and to protect hands from
sharp edges.
Prior to installation, remove all metallic
jewelry to prevent accidental exposure to
live circuits.
When installing modules in light rain,
morning dew, take appropriate measures
to prevent water ingress into the connec-
tor.
Do not allow children or unauthorized
persons near the installation site or mo-

dule storage area.
· Use electrically insulated tools to reduce the risk of
electric shock.
· If the disconnects and over current protection devices
(OCPDs) cannot be opened or the inverter cannot be
powered down, cover the fronts of the modules in the
PV array with an opaque material to stop the pro-
duction of electricity when installing or working on a
module or wiring.
· Do not install modules in strong wind. Do not use or
install damaged modules.
· Contact with module surfaces or frames may cause
electric shock if the front glass is broken or the backs-
heet is torn.
· The PV module does not contain any serviceable parts.
Do not attempt to repair any part of the module.
· Keep the junction box cover closed at all times.
· Do not disassemble a module or remove any module
part.
· Do not artificially concentrate sunlight on a module.
· Do not connect or disconnect modules when current
from the modules or an external source is present.

MECHANICAL / ELECTRICAL SPECIFICA-
TIONS
Module electrical ratings are measured under Stan-
dard Test Conditions (STC) of 1000 W/m2 irradiance,
with an AM1.5 spectrum, and a cell temperature of
25°C. Detailed electrical and mechanical characteri-
stics of CSI Solar Co., Ltd. crystalline silicon PV modu-
les can be found in Annex C (Module Specifications)
on www.csisolar.com. Main electrical characteristics
at STC are also stated on each module label. Please
refer to the datasheet or the product nameplate for
the maximum system voltage.
Under certain conditions, a module may produce
more current or voltage than its Standard Test
Conditions rated power. As a result, the module
short-circuit current under STC should be multiplied
by 1.25, and a correction factor should be applied to
the open-circuit voltage (see Table 1 below), when
determining component ratings and capacities. De-
pending on your local regulations, an additional 1.25
multiplier for the short-circuit current (giving a total
multiplier of 1.56) may be applicable when sizing
conductors and fuses.

Alternatively, a more accurate correction factor for
the open-circuit voltage can be calculated using the
following formula:
T is the lowest expected ambient temperature at the
system installation site.
αVoc (%/°C) is the voltage temperature coefficient of
the selected module (refer to corresponding datas-
heet).
Electrical calculations and design must be performed
by competent engineer or consultant.

UNPACKING AND STORAGE
PRECAUTIONS
· Modules should be stored in a dry and ventilated
environment to avoid direct sunlight and moisture. If
modules are stored in an uncontrolled environment,
the storage time should be less than 3 months and ex-
tra precautions should be taken to prevent connectors
from being exposed to moisture or sunlight, like using
connector endcaps.
· Unpack module pallets carefully, following the steps
shown on the pallet. Unpack, transport and store the
modules with care.
· Modules must always be unpacked and installed by
two people. Always use both hands when handling
modules.
· Do not lift modules by their wires or junction box, lift
them by the frame.
· Stacks of modules should contain no more than 12
modules, and the frames should be aligned.
· Do not place excessive loads on the module or twist
the module frame.
· Do not stand, step, walk and/or jump on modules
under any circumstances. Localized heavy loads may
cause severe micro-cracks at cell level, which in turn
may compromise module reliability. and void CSI Solar
Co., Ltd.’ s warranty.
· Do not support the module by the backsheet when
handling or installing the module.
· Do not carry modules on your head.
· Do not drop or place objects (such as tools) on the
modules.
· Do not use sharp instruments on the modules. Particu-
lar care should be taken to avoid module backsheets
being damaged by sharp objects, as scratches may
directly affect product safety.
· Do not leave modules unsupported or unsecured.
· Do not change the wiring of bypass diodes.
· Keep all electrical contacts clean and dry at all times.
· Do not expose the modules and its electrical contacts
to any unauthorized chemical substance (e.g. oil, lubri-
cant, pesticide, etc.).
PRODUCT IDENTIFICATION
· Each module has three identical barcodes (one in
the laminate under the front glass, the second on the
rear side of the module and the third on the frame)
that act as a unique identifier. Each module has a
CVOC = 1-αVoc ˣ (25 - T)

MODULE INSTALLATION
PRECAUTIONARY MEASURES AND
GENERAL SAFETY
· Prior to installing modules please obtain information
about any requirements and necessary approvals for
the site, installation and inspection from the relevant
authorities.
· Check applicable building codes to ensure that the con-
struction or structure (roof, facade, support, etc.) can
bear the module system load.
· CS-series solar modules have been qualified for Ap-
plication Class A (equivalent to Safety Class II require-
ments). Modules rated under this class should be used
in systems operating at voltage above 50V or power
above 240W, where general contact access is anticipa-
ted.
· CSI Solar Co., Ltd. modules have been certified as
Type 1 or Type 4 according to UL 61730 and Class C
according to IEC 61730-2, please refer to the datasheet
or the product nameplate for the detailed types.
· Consult your local authority for guidelines and require-
ments for building or structural fire safety.
UL 61730 SYSTEM FIRE RATING REQUIREMENTS
· A photovoltaic systems composed of UL 61730 certified
modules mounted on a UL 2703 certified mounting
system should be evaluated in combination with roof
coverings in accordance with UL 61730 standard, with
respect to meeting the same fire classification as the
roof assembly.
· Mounting systems with a System Fire Class Rating
(Class A, B or C), tested in conjunction with fire rated
“Type 1” or “Type 4” rated modules, are considered
acceptable for use with CSI Solar Co., Ltd. modules,
provides the mounting system does not violate any
other requirements of this manual.
· Any mounting system limitations on inclination or
accessories required to maintain a specific System
Fire Class Rating should be clearly specified in the
installation instructions and UL 2703 certification of the
mounting system supplier.
· When installing modules, ensure the supporting roof
has a fire resistant roof covering rated for the applicati-
on.
· The fire rating for this module is only valid when the
product is installed as specified in the mechanical
mounting instructions.
ENVIRONMENTAL CONDITIONS
· The module is intended for use in general open-air
climates, as defined in IEC 60721-2-1: Classification
of environmental conditions Part 2-1: Environmental
conditions appearing in nature. Temperature and
humidity.
· Please consult the CSI Solar Co., Ltd. technical support
department for more information on the use of modu-
les in special climates, such as an altitude greater than
2000m.
Do not install modules near open flames
or flammable materials.
Do not immerse modules in water or
constantly expose modules to water (eit-
her fresh or salt) (i.e. from fountains, sea
spray).
· Exposing modules to salt (i.e. marine environments) or
sulfur (i.e. sulfur sources, volcanoes) incurs the risk of
module corrosion.
· Do not expose modules and their electrical contacts to
any unauthorized chemical substances (e.g. oil, lubri-
cant, pesticide, etc. ), as modules may incur damages.
· Failure to comply with these instructions will void CSI
Solar Co., Ltd. warranty.

INSTALLATION REQUIREMENTS
· Ensure that the module meets the general technical
system requirements.
· Ensure that other systems components do not dama-
ge the module mechanically or electrically.
· Modules can be wired in series to increase voltage or
in parallel to increase current. To connect modules in
series, connect the cables from the positive terminal
of one module to the negative terminal of the next
module. To connect in parallel, connect the cables from
the positive terminal of one module to the positive
terminal on the next module.
· The quantity of bypass diodes in the module’s junction
box provided may vary depending on the model series.
· Only connect the quantity of modules that corres-
ponds to the voltage specifications of the inverters
used in the system. In addition modules must not be
connected together to create a voltage higher than
the maximum permitted system voltage stated on
the module nameplate, even under the worst local
temperature conditions (see Table 1 for the correction
coefficients that apply to open-circuit voltage).
· A maximum of two strings can be connected in parallel
without using an over-current protection device (fuses,
etc.) incorporated in series within each string. Three or
more strings can be connected in parallel if an appro-
priate and certified over-current protection device is
installed in series within each string. And it shall be
ensured in the PV system design that the reverse cur-
rent of any particular string is lower than the module
maximum fuse rating at any circumstance.
· For high power bins modules such as CS1 series inten-
ded to be used on rooftop applications, in agreement
with IEC62548:2016 Photovoltaic (PV) arrays design
requirements, blocking diodes should be used in each
PV array module string as exclusive mean of protection
against reverse currents where three or more strings
are connected in parallel. Where permitted by your
local electrical code, blocking diodes can also be used
for over overcurrent protection, in place of fuses or
other OCPD devices.
· Only modules with similar electrical parameters should
be connected in the same string to avoid or minimize
mismatch effects in arrays.
· To minimize risk in the event of an indirect lightning
strike, avoid forming loops with the wiring when desig-
ning the system.
· The recommended maximum series fuse rating is
stated in a table in the Annex C.
· Modules should be safely fixed to bear all expected
loads, including wind and snow loads.
· A minimum clearance of 6.5 mm (0.25 in) between
modules is required to allow for thermal expansion of
the frames.
· The small drainage holes on the underside of the mo-
dule must not be blocked.
OPTIMUM ORIENTATION AND TILT
· To maximize your annual yield, find out the optimum
orientation and tilt for PV modules in your region.
The highest yields are achieved when sunlight shines
perpendicularly onto the PV modules
AVOID SHADING
· Even minor partial shading (e.g. from dirt deposits)
reduces yields. A module can be considered to be uns-
haded if its entire surface is free from shading all year
round. Sunlight should be able to reach the module
even on the shortest day of the year.
· Constant shading conditions can affect module service
lifetime, due to accelerated ageing of the encapsulati-
on material and thermal stress on the bypass diodes.
RELIABLE VENTILATION
· Sufficient clearance (at least 10 cm (3.94 in)) between
the module frame and the mounting surface is
required to allow cooling air to circulate around the
back of the module. This also enables condensation or
moisture to dissipate.
· According to UL 61730, any other specific clearance
required for maintaining a system fire rating should
prevail. Detailed clearance requirements pertaining to
system fire ratings must be provided by your racking
supplier.

5.1
MODULE WIRING
CORRECT WIRING SCHEME
· Cable management scheme should be reviewed and
approved by the EPC contractor; in particular required
cable lengths should be cross-checked considering
the specificities of the tracker structure like bearing
house gaps. If longer cable or additional jumper cable
is requested, please contact Canadian Solar’s sales
representative in advance.
· Ensure that the wiring is correct before starting up the
system. If the measured open circuit voltage (Voc) and
short-circuit current (Isc) differ from the specifications,
this indicates that there is a wiring fault.
· When modules have been pre-installed but the system
has not been connected to the grid yet, each module
string should be kept under open-circuit conditions
and proper actions should be taken to avoid dust and
moisture penetration inside the connectors.
· The maximum distance between two adjacent module
frames should be within 50 mm (1.96in) for the side
with mounting clamps, and within 25 mm (0.98in) for
the side without mounting clamps, in order to meet
the system cable scheme.
CORRECT CONNECTION OF PLUG CONNECTORS
· Make sure that all connections are safe and properly
mated. The PV connector should not be subjected to
stress from the exterior. Connectors should only be
used to connect the circuit. They should never be used
to turn the circuit on and off.
· Connectors are not waterproof when unmated. When
installing modules, connector should be connected to
each other as soon as possible or appropriate measu-
res (like using connector endcaps) should be taken to
avoid moisture and dust penetrating into the connec-
tor.
· Do not clean or precondition the connectors using
lubricants or any unauthorized chemical substances.
USE OF SUITABLE MATERIALS
· Only use dedicated solar cable and suitable connectors
(wiring should be sheathed in a sunlight-resistant con-
duit or, if exposed, should itself be sunlight-resistant)
that meet local fire, building and electrical regulations.
Please ensure that all wiring is in perfect electrical and
mechanical condition.
· Installers may only use single-conductor cable listed
and labeled as USE-2 or PV wire which is 90°C wet
rated in North America, and single conductor cable,
2.5-16 mm² (5-14 AWG), 90°C wet rated in other areas
(i.e. TUV 2PfG1169 or EN50618 approved), with proper
insulation which is able to withstand the maximum
possible system open-circuit voltage.
· Only copper conductor material should be used. Select
a suitable conductor gauge to minimize voltage drop
and ensure that the conductor ampacity complies with
local regulations (i.e. NEC 690.8(D))..
CABLE AND CONNECTOR PROTECTION
· Secure the cables to the mounting system using UV-re-
sistant cable ties. Protect exposed cables from damage
by taking appropriate precautions (e.g. placing them
inside a metallic raceway like EMT conduit). Avoid
exposure to direct sunlight.
· A minimum bending radius of 60 mm (2.36 in) is
required when securing the junction box cables to the
racking system.
· Do not place connectors in locations where water
could easily accumulate.
5.2
GROUNDING
· For grounding requirements in North America, a
module with exposed conductive parts is considered to
comply with UL 61730 only when it is electrically groun-
ded in accordance with both the instructions presented
below and the requirements of the National Electrical
Code. Any grounding means used with CSI Solar Co.,
Ltd. modules should be NRTL certified to UL 467 and
UL 2703 standards. Please consult our technical service
team for the formal approval process.
· For grounding requirements in other areas, although
the modules are certified to Safety Class II, we recom-
mend them to be grounded and that module installa-

tion should comply with all applicable local electrical
codes and regulations. Grounding connections should
be installed by a qualified electrician. Connect module
frames together using adequate grounding cables: we
recommend using 4-14 mm² (AWG 6-12) copper wire.
Holes provided for this purpose are identified with a
grounding symbol (IEC61730-1). All conductive
connection junctions must be firmly fixed.
· Do not drill any extra ground holes for convenience
this will void the modules warranty.
· All bolts, nuts, flat washers, lock washers and other
relevant hardware should be made of stainless steel,
unless otherwise specified.
· CSI Solar Co., Ltd. does not provide grounding hard-
ware.
· One grounding method is recommended for CSI Solar
Co., Ltd. classic modules, as described below. For
alternative grounding methods, please refer to Annex
B (Alternative Grounding Methods) of this installation
manual. It may not be possible to use standard groun-
ding methods for certain module ranges. Please refer
to Annex B for more details.
1. To x the wire between
the at washer and
cup washer, place the
cup washer (concave
side up) between the
frame and the wire.
2. Then tighten the bolt
using the toothed nut.
GROUNDING METHOD:
BOLT + TOOTHED NUT + CUP WASHER.
· A grounding kit containing an M5 (3/16”) SS cap bolt, an
M5 (3/16”) SS flat washer, an M5 (3/16”) SS cup washer,
and an M5 (3/16”) SS nut (with teeth) is used to attach
copper grounding wire to a pre-drilled grounding hole
on the frame (see image above).
· Place the wire between the flat washer and the cup
washer. Ensure that the cup washer is positioned bet-
ween the frame and the wire with the concave side up
to prevent galvanic corrosion. Tighten the bolt securely
using the SS toothed nut. A wrench may be used to do
this. The tightening torque is 3-7 Nm (2.2-5.2 ft-lbs).

MOUNTING INSTRUCTIONS
The applicable regulations pertaining to work safety,
accident prevention and securing the construction
site must be observed. Workers and third party per-
sonnel shall wear or install fall arrest equipment. Any
third party need to be protected against injuries and
damages.
· The mounting design must be certified by a registered
professional engineer. The mounting design and pro-
cedures must comply with all applicable local codes and
requirements from all relevant authorities. The module
is considered to be in compliance with UL 61730 and
IEC 61215 only when the module is mounted in the
manner specified by the mounting instructions inclu-
ded in this installation manual.
· Any module without a frame (laminate) shall not be
considered to comply with the requirements of UL
61730 unless the module is mounted with hardware
that has been tested and evaluated with the module
under this standard or by a field Inspection certifying
that the installed module complies with the require-
ments of UL 61730.
· CSI Solar Co., Ltd. does not provide mounting hard-
ware.
· Classic modules can be mounted onto a support struc-
ture using one of several approved methods. One of
such methods is described below. For details of other
mounting methods and the methods recommended

by CSI Solar Co., Ltd. for special module ranges, please
refer to the Annex A (Alternative Mounting Methods) of
this installation manual. For information about other in-
stallation methods, please contact your local represen-
tative. Failure to use a recognized installation method
will void the CSI Solar Co., Ltd. warranty.
· Use appropriate corrosion-proof fastening materials.
All mounting hardware (bolts, spring washers, flat
washers, nuts) should be hot dip galvanized or stainless
steel.
· Use a torque wrench for installation.
· Do not drill additional holes or modify the module
frame. Doing so will void the warranty.
· Classic modules can be installed in either landscape or
portrait orientations. Refer to the detailed instructions
for further guidance. Please note that in areas with he-
avy snowfall (> 2400 Pa) further countermeasures such
the use of additional support bars should be conside-
red to avoid snow loads damaging the lowest row of
modules.
· In cases where an additional support bar is recommen-
ded to improve both mechanical stability and long-term
module performance, we recommend selecting a
sufficiently resistant material. CSI Solar Co., Ltd. recom-
mends bars with a minimum thickness of 50 mm (1.97
in). The support bar centerline should be positioned wi-
thin 100 mm (3.94 in) of the side frame centerline (slight
shifts may be necessary to access module grounding
holes).
· The loads described in this manual correspond to test
loads. For installations complying with IEC 61215-2:2016
and UL 61730, a safety factor of 1.5 should be applied
for calculating the equivalent maximum authorized
design loads. Project design loads depend on construc-
tion, applicable standards, location and local climate.
Determination of the design loads is the responsibility
of the racking suppliers and/or professional engineers.
For detailed information, please follow local structural
code or contact your professional structural engineer.

MAINTENANCE
· Do not make modifications to any component of the
PV module (diode, junction box, plug connectors or
others).
· Regular maintenance is required to keep modules clear
of snow, bird droppings, seeds, pollen, leaves, bran-
ches, dirt spots, and dust.
· Modules with sufficient tilt (at least 15°), generally
may not require cleaning (rain will have a self-cleaning
effect). If the module has become soiled, wash with
water and a non-abrasive cleaning implement (sponge)
during the cool part of the day. Do not scrape or rub
dry dirt away, as this may cause micro scratches.
· Snow should be removed using a soft brush.
· Periodically inspect the system to check the integrity of
all wiring and supports.
· To protect against electric shock or injury, electrical or
mechanical inspections and maintenance should be
performed by qualified personnel only.
· Please refer to Annex C (Module Cleaning Guide) for
additional information on this topic.

www.csisolar.com
| 13
· All the basic requirements of the main installation
manual should also apply to alternative mounting
methods, unless otherwise specified.
· The loads described in this manual correspond to
test loads. For installations complying with IEC 61215-
2: 2016 and UL 1703, a safety factor of 1.5 should
be applied for calculating the equivalent maximum
authorized design loads. Project design loads depend
on construction, applicable standards, location and
local climate. Determination of the design loads is the
responsibility of the racking suppliers or professional
engineers. For detailed information, please follow local
structural code or contact your professional structural
engineer.
MOUNTING METHOD A:
CLAMPING
· The mounting method has been qualified by CSI Solar
Co., Ltd., as well as certified by VDE and CSA.
· Top or bottom clamping methods will vary and are de-
pendent on the mounting structures. Please follow the
mounting guidelines recommended by the mounting
system supplier.
· Each module must be securely fastened at a minimum
of four points on two opposite sides. The clamps should
be positioned symmetrically. The clamps should be
positioned according to the authorized position ranges
defined in table A.
· Install and tighten the module clamps to the mounting
rails using the torque stated by the mounting hardware
manufacturer. M8 X 1.25 (5/16”) bolt and nut are used
for this clamping method.
· Tightening torques should be within 17~23 Nm
(12.5~17.0 ft-lbs) for M8 (5/16”) coarse thread bolts,
depending on the bolt class. For the bolt grade, the
technical guideline from the fastener suppliers should
be followed. Different recommendations from specific
clamping hardware suppliers should prevail.
· The system designer and installer are responsible for
load calculations and for proper design of support
structure.
· CSI Solar Co., Ltd.’s warranty may be void in cases whe-
re improper clamps or unsuitable installation methods
are found. When installing inter-modules or end-type
clamps, please take the following measures into ac-
count:
Do not bend the module frame.
Do not touch or cast shadows on the front glass.
Do not damage the surface of the frame (to the
exception of the clamps with bonding pins).
Ensure the clamps overlap the module frame by at
least 5 mm (0.2 in).
Overlap in length by at least
a) 80 mm (3.15 in) when 2400 Pa < uplift load ≤ 4000
Pa is required.
b) 40 mm (1.57 in) when uplift load ≤ 2400 Pa is
required.
Ensure the clamp thickness is at least 3 mm (0.12 in)
· Clamp material should be anodized aluminum alloy or
stainless steel.
· Clamp positions are of crucial importance for the
reliability of the installation. The clamp centerlines
must only be positioned within the ranges indicated in
table A, depending on the configuration and load. For
configurations where the mounting rails run parallel to
the frame, precautions should be taken to ensure the
bottom flange of the module frame overlaps the rail by
15 mm (0.59 in) or more.
