isable to cover themodules with an opaque material. Do not touch the terminals with both hands and always useinsulated tools on the electrical connections.

Only allow access to the facility by qualified personnel.

Reversing the polarity of the cables destroys the bypass diodes of the junction box.

In normal conditions, the module can produce more current or voltage than the indicated for standardmeasurement conditions. So that, when dimensioning the system (cables section, fuses,…) the Iscand Voc values should be multiplied by 1,25.

Keep children and animals away from PV modules.

Install the modules in a strong structure and that this maintains the fire safety class.

Avoid uneven shade on the PV module surface. Shaded cells may become hot (“hot spot”phenomenon) which may result in permanent damage to the module.

Follow all safety precautions of other system components used.

Use module for its intended function only.

: In corrosive environments (salt spray), place nylon washers to insulate thepanel from the metal parts of the structure.

The aluminium frames of ATERSA’s photovoltaic modules have side channels that makeit easier to fix the module onto the profiles of the installation.

The Hook Fixing System is used to install the modules.This system can be installed onstandard structures , “U” type guide rail or guide insertion.

Fixing on standard structures is carried out using the dead-end clamp, the M8x20serrated head Allen screw, flat washer and M8 nut. View image (4).

For this type of installation you need a 41x41mm or 41x21mm "U" type perforatedprofile. These elements do not come with the Hook Fixing System.

Appropriate cable sections must be used to prevent voltage drops, which could cause adrop in the power of the installation. As a rule, voltage drops in excess of 1,5% mustnot be allowed.

(*)Check table of intensities max. of manufacturer's cable and the applicableregulations.

5.2.- Electrical Installation

CABLE SECTION (Copper section):

Put the first two fixing sets in place, and ensure they are vertically aligned. Fullytighten the Allen screw (6).

Attach the other two fixing sets, aligning them vertically and move them along the railuntil they reach the panel.

Check that the modules are horizontally and vertically aligned and fully tighten thescrews to ensure the modules are firmly fixed to the guide rail.

The final fixing sets should be attached in the same way as the first two but in reverse.Take a module that is already in place and then attach the set of fixings.

The modules are ready for installation by inserting into a guide system.After insertion into the guide rails, panels must be fixed to prevent free sliding on theguides.

TOTAL SECTION (External diameter):

ELECTRICAL CONNECTION:

A direct cable connection can be made to the direct connect junction box using (max.4mm ,AWG12) the cable termination spring clips in the junction box. In the mannershown below, direct connection of cable sizes AWG14 and AWG12 can beaccommodated. The sealing grommet in the 2 rail assembly can accommodateinsulation diameters up to 8.0mm (0.31 inches). To ensure proper termination, cableinsulation should be stripped as shown in figure(7).

On multi-stranded conductors, it is recommended to use wire pins or at least to twistthe strand bundle to ensure all strands are captured in the spring clip. To open thespring clip window for the cable, use the appropriate tool (see ATERSA product) or alittle screw, to insert vertically into the window as seen in figure 1.View image (8)

The cable can be inserted through the opened window into the clip (figure 2). Once thecable is installed, lift the screw and the cable is fixed. Attention to the polarity of thewires. Make sure that the cable is inside the clip and is fixed correctly, if the cable is notinstalled correctly the juntion box will be deteriorated (electric arc).

After termination, tighten the grommet nut to compress the grommet around thecable. Tightening torque for cable screw nut max. 1.5 Nm (0.34 lbf) depends on thetype of cable isolation. Hold cable screw joint with tool.

Connection boxes with integrated cable glands are used with 4mm² cable (AWG 12).The tightening torque is 1.3 Nm (0.29 lbf). For this is recommended the use of aslotted socket wrench with wrench size oh 13mm (0.51 inches). ,
