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, clothes, etc.) must be worn during installation to prevent direct
contact with 30 V DC or greater, and to protect hands from sharp edges.
Use electrically insulated tools to reduce the risk of electric shock.
Prior to installation, remove all metallic jewelry to prevent accidental exposure to live circuits.
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
production of electricity when installing or working on a module or wiring.
When installing modules in light rain, morning dew, take appropriate measures to prevent water ingress
into the connector.
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
backsheet 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.
Do not allow children or unauthorized persons near the installation site or module storage area.
3.0 MECHANICAL / ELECTRICAL SPECIFICATIONS
Module electrical ratings are measured under Standard Test Conditions (STC) of 1000 W/m

irradiance, with an
AM1.5 spectrum, and a cell temperature of 25°C. Detailed electrical and mechanical characteristics of Canadian
Solar Inc. crystalline silicon PV modules can be found in Annex C (Module Specifications) on
www.canadiansolar.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. Depending 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.
