| Safety in Hazardous Locations 4.0 UNPACKING AND STORAGE PRECAUTIONS · With regard to modules that are suitable for use in Class I, Division 2, Groups A, B, C and D hazardous Precautions locations, strict compliance with the following If modules are stored in an un- WARNINGS is necessary to avoid any personal controlled environment for less injury or damage to property.
|5 · Do not drop or place objects (such as tools) on the modules. · Do not carry modules on your head. 5.0 Module Installation Precautions Measures AND GENERAL SAFETY · Do not use sharp instruments on the modules. Particular care should be taken to avoid module Prior to installing modules please obtain backsheets being damaged by sharp objects, as information about any requirements scratches may directly affect product safety.
| Environmental conditions · Only modules with similar electrical outputs · The module is intended for use in general open-air climates, as defined in IEC 60721-2-1: should be connected in the same string to avoid or minimize mismatch effects in arrays. Classification of environmental conditions Part -2-1: Environmental conditions appearing in nature Temperature and humidity. · To minimize risk in the event of an indirect lightning strike, avoid forming loops when designing the system.
|7 5.1 Module WIRING 5.2 Equipment GROUNDING Correct wiring scheme · A module with exposed conductive parts is only considered to comply with UL1703 only when it · Ensure that the wiring is correct before starting is electrically grounded in accordance with both up the system. If the measured open circuit the instructions presented below and the require- voltage (Voc) and short-circuit current (Isc) ments of the National Electrical Code.
| Grounding Method: Bolt + toothed Nut + Cup washer. When diameter of the grounding holes is 0.20 in (5 mm) (CSA certified). · A grounding kit containing an M5 SS cap bolt, an M5 SS flat washer, an M5 SS cup washer, and an M5 SS nut (with teeth) is used to attach copper grounding wire to a pre-drilled grounding hole on the frame (see image below). · Place the wire between the flat washer and the cup washer.
|9 · The mounting design must be certified by a regis- of modules. tered professional engineer. The mounting design and procedures must comply with local codes and requirements from all relevant authorities. · In cases where an additional support bar is recommended to improve both mechanical stability and long-term module performance, · The module is only considered to comply with UL Canadian Solar recommends selecting 1703 when mounted as specified in the instruc- sufficiently resistant material.
| · Modules should be bolted at the following hole locations depending on the configuration and load: Table 1: Approved bolting methods Uplift load ≤ 2400 Pa Uplift load ≤ 2400 Pa Downforce load ≤ 2400 Pa 2400 Pa ≤ Downforce load ≤ 5400 Pa Bolting on long side frame Use 4 standard mounting holes (long side) Mounting rails shall run perpendicularly or parallel to the long side frame Bolting on short side frame (except for CS6X series) Use 4 standard mounting holes (short side) Mounting rails sha
