Canadian Solar Inc. shall not be held responsible for damages of any kind, including – without limitation – bodily harm, injury or damage to property, in connection with handling PV modules, system installation, or compliance or non-compliance with the instructions set forth in this manual.

2.0 SAFETY PRECAUTIONS

GENERAL SAFETY

· All Modules must be installed by licensed electricians 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 electrical codes.

Protective clothing (non-slip gloves, clothes, etc.) must be worn during installation to prevent direct contact with 30 V DC or greater, and to protect your hands against 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 avoid water permeate into the connector.

· When installing modules in strong wind, take appropriate safety measures to avoid damage to the modules or injuries to people.

· Use electrically insulated tools to reduce the risk of www.canadiansolar.com

Ɉ | electric shock.

· If the disconnects and OCPD's cannot be opened or the inverter cannot be powered down, cover the fronts of modules in the PV array with an opaque material to stop the production of electricity when installing or working on a module or wiring.

· Do not use or install broken modules.

· Contact with module surfaces or frames may cause electric shock if the front glass is broken or the backsheet is torn.

25°C. Detailed electrical and mechanical characteristics of Canadian Solar Inc. crystalline silicon PV modules can be found in our Installation Manual

$QQH[6HFWLRQ$QQH[&0RGXOH6SHFLȴFDWLRQVRQ www.canadiansolar.com.

Main electrical characteristics under STC are also stated on each module label. Please refer to the datasheet or the product nameplate for the maximum system voltage.

· Keep the junction box cover closed at all times.

· The PV module does not contain any serviceable parts.

· Do not attempt to repair any part of the module.

· Do not disassemble a module or remove any module part.

· Do not DUWLȴFLDOO\FRQFHQWUDWHVXQOLJKWRQDPRGXOH

Under certain conditions, a module may produce more current or voltage than under its Standard Test

Condition's rated power. As a result, a module’s open-circuit voltage and short-circuit current under

STC should be multiplied by 1.25 when determining component voltage ratings, conductor ampacities, overcurrent device ratings, and the size of controls connected to the PV output. 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, as described in section 690-8 of U.S. NEC.

· Do not connect or disconnect modules when current from the modules or an external source is present.

· Do not allow children or unauthorized persons near the installation site or module storage area.

4.0 UNPACKING AND STORAGE PRECAUTIONS

Safety in Hazardous Locations

· With regard to modules that are suitable for use in

Class I, Division 2, Groups A, B, C and D hazardous locations, strict compliance with the following

WARNINGS is necessary to avoid any personal injury or damage to property.

PRECAUTIONS

Module 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 extra precautions should be taken to prevent connectors from being exposed to moisture or sunlight.

Warning: Explosion hazard – do not disconnect equipment unless the power has been switched off or the area is known to be non-hazardous.

Avertissement: Risque d’explosion –

Avant de déconnecter l’equipement, couper le courant ou s’assurer que l’emplacement est désigné non dangereux

· To minimize risk in the event of an indirect lightning strike, avoid forming loops when designing the system.

Do not immerse modules in water or constantly expose modules to water (either fresh or salt) (i.e. from fountains, sea spray). · The recommended maximum series fuse rating is stated in a table in the Annex.

· Exposing modules to salt (i.e. marine environments) or sulfur (i.e. sulfur sources, volcanoes) incurs the risk of module corrosion.

· Failure to comply with these instructions will void

Canadian Solar Inc warranty.

· Modules should be safely fixed to bear all expected loads, including wind and snow loads. A minimum clearance of 0.25 in (6.5 mm) or more between modules is required to allow for thermal expansion of the frames.

INSTALLATION REQUIREMENTS

· The small drainage holes on the underside of the module must not be blocked.

· Ensure that the module meets the general technical system requirements.

OPTIMUM ORIENTATION AND TILT

· Ensure that other system components do not damage 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.

y 7RPD[LPL]H\RXUDQQXDO\LHOGȴQGRXWWKH 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

· The quantity of bypass diodes in the module's junction box may vary depending on the model series.

· Even minor partial shading (e.g. from dirt deposits) reduces yields. A module can be considered to be unshaded 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.

· Only connect the quantity of modules that corresponds to the voltage specifications of the inverters used in the system. Modules must NOT be connected together to create a voltage higher than the maximum permitted system voltage, even under the worst local temperature conditions.

· A maximum of two strings can be connected in

· Constant shading conditions can affect module service lifetime, due to accelerated ageing of the encapsulation material and thermal stress on the bypass diodes.

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)).

5.1 MODULE WIRING

CORRECT WIRING SCHEME

· Ensure that the wiring is correct before starting up the system. If the measured open circuit voltage (Voc) and short-circuit current (Isc) differ substantially from the specifications, this indicates that there is a wiring fault.

CABLE AND CONNECTOR PROTECTION

· Secure the cables to the mounting system using

UV-resistant cable ties. Protect exposed cables from damage by taking appropriate precautions

(e.g. placing them inside a plastic conduit). Avoid exposure to direct sunlight.

· A minimum bending radius of 2.36 in (60 mm) is

required when securing the junction box cables to

the racking system.

· When modules have been pre-installed but the system has not been connected to the grid yet, each module string should be kept under opencircuit conditions and proper actions should be taken to avoid dust and moisture penetration.

· Do not place connectors in locations where water could easily accumulate.

5.2 EQUIPMENT GROUNDING

CORRECT CONNECTION OF PLUG CONNECTORS

· Make sure that connections are safe and tight.

Plug 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.

· A module with exposed conductive parts is only considered to comply with UL1703 only when it is electrically grounded in accordance with both the instructions presented below and the requirements of the National Electrical Code.

· Connectors are not waterproof when unmated.

When installing modules, connector should be connected to each other as soon as possible or appropriate measures should be taken to avoid moisture penetrating into the connector.

USE OF SUITABLE MATERIALS

· Modules must be grounded, and module installation must comply with all local electrical codes and regulations.

· Grounding connections should be installed by a

see 690.7(A)

44.62V

NEC 690.7(A) requires that if the PV module manufacturer provides a temperature coefficient of open-circuit voltage, it must be used to calculate the PV array's maximum system voltage. It includes an information note recommending the use of the ASHRAE 'Extreme Annual

Mean Minimum Design Dry Bulb Temperature' as the design low temperature. Using these values, the module Voc (40.1V) will increase to

44.62V at the design low temperature ( -14°C).

(-14°C - 25°C) X -0.116V/C + 40.1V = 44.62V

The module Voc at the design low temperature is 44.62V.

44.62V X 1 = 44.62V

PV Source Circuit maximum Voc must not exceed

600V

see Article 100

Equipment maximum rated output current is 56A

56A

B. Ampacity of Conductor

see Table 310.15(B)(16)

Ampacity (30°C) for a copper conductor with 90°C insulation in conduit/cable is 195A.

195A

C. Derated Ampacity of Conductor 177.45A

see Table 310.15(B)(3)(c), Table 310.15(B)(3)(a), and Article 100

The temperature factor for 90°C insulation at 36°C is 0.91.

The fill factor for a conduit/cable that has 2 wires is 1.

The ampacity derated for Conditions of Use is the product of the conductor ampacity (195A) multiplied by the temperature factor (0.91) and by the fill factor (1).

195A X 0.91 X 1 = 177.45A

D. Max Current for Terminal Temp. Rating

see 110.14(C)

175A

The lowest temperature limit for this conductor at any termination is

75°C.

Using the method specified in 110.14(C), the maximum current permitted to ensure that the device terminal temperature does not exceed its 75°C rating would be the amount referenced in the 75°C column in Table

310.15(B)(16), which is 175A.

E. Minimum Allowed OCPD Rating

see 240.4

NEC 690.9(B) requires that the OCPD be rated for no less than 1.25

times the Continuous Current of the circuit.

56A X 1.25 = 70A

70A

F. Minimum Required EGC Size

see 250.122(B)

2 AWG

Where conductors are oversized, the EGC must be oversized by the same rate. Table 250.122, gives a minimum EGC size of 8 AWG.

Multiplied by the oversize rate, this yields 52.64689kcmil corresponding to 2 AWG.

(133.1kcmil / 41.74kcmil) X 16.51kcmil = 52.64689kcmil

G. Minimum Recommended Conduit Size 1.25" dia.

see 300.17

The total area of all conductors is 0.5604in². With a maximum fill rate of

0.4, the recommended conduit diameter is 1.25.
