Page 2: General Information
EDF ENR PWT 1.0 GENERAL INFORMATION This general manual provides important safety information relating to the installation, maintenance and handling of CS-series solar modules. System users and professional installers should read this manual carefully and strictly follow the instructions. Failure to follow these instructions may result in death, injury or property damage. The installation of solar modules requires specialized skills and should only be performed by licensed professionals. -
Page 3: Mechanical / Electrical Specifications
EDF ENR PWT Do not install or handle the modules when they are wet or during periods of high wind. Do not use or install broken modules. If the front glass is broken, or the back sheet is torn, contact with any module surface or the frame can cause electric shock. -
Page 4: Unpacking And Storage
EDF ENR PWT 4.0 UNPACKING AND STORAGE Precautions and General Safety Store modules in a dry and ventilated room. Do not allow children and unauthorized persons near the installation site or storage area of modules. Do not transport modules in an upright position. ... - Page 5 EDF ENR PWT Do not immerse modules in water or constantly expose modules to water (either fresh or salt) (i.e. from fountains, sea spray). Exposing modules to salt (i.e. marine environments) and sulfur (i.e. sulfur sources, volcanoes) risks module corrosion.

Page 6: Module Wiring
EDF ENR PWT 5.1 MODULE WIRING Correct wiring scheme When designing the system, avoid forming loops (to minimize risk in the event of an indirect lighting strike). Make sure that wiring is correct before starting up the system. If the measured open circuit voltage (Voc) and short-circuit current (Isc) differ from the specifications, then there is a wiring fault. -
Page 7: Mounting Instructions
Grounding hardware is not provided by EDF ENR PWT. One grounding method approved by North-American certification body (CSA) is recommended for Photowatt modules, as described below. For alternative CSA qualified grounding methods, please refer to Annex B. Method: Bolt + Nut with teeth + Cup washer When diameter of the grounding holes is 5mm (CSA certified). -
Page 8: Mounting Method: Bolting
EDF ENR PWT Cables and connectors The mounting design must be certified by a registered professional engineer. The mounting design and procedures shall comply with local electrical and building codes. The module is considered to be in compliance with UL 1703 only when the module is mounted in the manner specified by the mounting instructions below. -

- Page 12 EDF ENR PWT ANNEX B: ALTERNATIVE GROUNDING METHODS All the requirements of paragraph 5.2 should apply to the alternative grounding methods. Each method has been qualified by at least one North-American certification body, as specified. For grounding methods A and B, connect module frames to each other using suitable grounding conductor with ring terminals.
- Page 13 EDF ENR PWT Each module must be securely fastened at a minimum of 4 points on two opposite sides. The clamps should be positioned according to the authorized position ranges defined in table C-1. Install and tighten the module clamps to the mounting rails using the torque stated by the mounting hardware manufacturer. System designer and installer are responsible for load calculations and for proper design of support structure.
