3. GENERAL INFORMATION 3.1 COMPONENTS OF THE MODULE The structure of the module is shown in the -gure below. Three types of labels are glued to each module which provide the following information: Data plate:product type, rated power, rated current, rated voltage, open circuit voltage, short circuit, current under test conditions, certi-cation indicator, maximum system voltage, etc. -
Page 6: General Safety
Please be aware that there is a serious risk of various types of injury occurring during installation, including the risk of electric shock. All UNICAL modules are equipped with a permanently fixed junction with a terminal block that accepts various types of wiring or with a special cable assembly. -

3.4 - INSTALLER SAFETY Do not open the package -until you reach the installation site (during transportation and storage, the modules must be protected with the package. Please protect the module package. When loading or unloading the modules, handle with care. Do not drop the packed pallet of modules directly. -

/ Extremely cold areas / Areas with strong winds / Installations over or near water / Areas where installations are subject to damage caused by salt water / Small islands or desert areas. UNICAL suggests that the modules must not be installed or used in areas where hail, snow, sand, dust, air pollution, soot, etc., are excessive. -
Page 9: Inclination Angle
UNICAL recommends installing the modules with an angle of inclination of at least 9 degrees, thus facilitating the washing of dust by natural rain and regular cleaning will not be necessary, there will be no stagnation of water on the surface of the module, preventing the glass from molding (which could affect the degradation of the modules). -
Page 10: Assembly With Bolts
5.2.1 ASSEMBLY WITH BOLTS Through the mounting hole on the rear frame of the PV module, the module can be fixed on the support with bolts. A module typically has 4 or 8 mounting holes and is installed with M8 bolts. The details are shown in the -gure below: 00274174 F23EG000XX Hole... - Page 11 5.2.2 ASSEMBLY WITH CLAMP Under no circumstances should the clamp touch the glass or deform the frame. The clamp interface to the front of the frame must be smooth and flat to prevent the frame or other components from detaching or damaging the surface.

Page 15: Electrical Installation
Module -until the connector is fully seated. Use field wiring with suitable cross sections approved for use at the maximum short circuit current of the modules. UNICAL advises installers to use only sunlight-resistant cables suitable for direct current wiring (DC) in photovoltaic systems. -
Page 16: Connectors
ICE 62852 standard. 6.3 BY-PASS DIODES The junction boxes used with the UNICAL modules contain bypass diodes wired in parallel with the string photovoltaic cell. In the event of partial shading, the diodes bypass the current generated by the unshaded cells, thus limiting module heating and performance losses. -
Page 17: Earthing
7 EARTHING Chassis grounding is within the local code requirements at the installation location. When this grounding is required, refer to the connection example in the figure. Please use caution when grounding the system so that removing one module from the circuit does not disrupt the grounding of any other modules. The modules must be grounded at the same electrical point. -
Page 18: Cleaning
IPA flows into the gap between the edge of the module and the module frame. In order to avoid potential risks of electric shocks or burns, UNICAL suggests cleaning the modules early in the morning and in the evening with low irradiation and low temperature of the modules especially in areas with high average temperatures. - Page 19 8.3 INSPECTION OF CONNECTORS AND CABLES The following preventive inspection is recommended to be carried out twice a year. Check for cracks or gaps in the silicone near the junction box. In order to ensure the operational safety of the control panel and the modules, the cables and connectors in the modules must be fixed to avoid damage caused by the continuous impact on the modules in the environment due to strong winds.
