Use the following formula to calculate the section:
Where L is the lenght of the line in meters, I
is the maximum current in amps, the maximum permited voltage drop in volts is
and
is the copper
conductivity at temperature T. E.g The copper conductivity at 90ºC would be
= 44.
(*)Check table of intensities max. of manufacturer's cable and the applicable regulations.
The section of the cable depends on the type of cable gland used. In this case, it must have a diameter of between 4.5 mm and 10 mm. Install the terminal
already crimped together with the cable, which must never exceed the maximum diameter admitted by the 10 mm cable gland.
Pass the cables through the cable glands and firmly fasten the cables to the connection screws in the box, paying particular attention to the polarity, which
is shown on the circuit.
It is recommended that the cables should be crimped with spade or ring terminals for M5, as this guarantees and facilitates the connection of the module.
The cable terminal must be fastened to the connection screw using a M5 nut, a flat washer and a serrated washer and the proper torque values should be
between 3,8 to 4Nm. The junction box is always supplied with these components, with the exception of the cable and terminal (according to models).
For the junction box to maintain its Class II safety standard, the cables must also be Class II.
Connect the modules and the support structure to ground, which will ensure that any current leakage to any of the components of the installation will not
reach the installer or user under any circumstances.
The module frame material is aluminium. Ground wires must be connected to the module’s frame at the ground location (Figure 9). The ground wire must
be
To ground the modules, you must use a stainless steel lug terminal
and a self-tapping screw between 4,2x4,5mm and 4,2x16mm. Terminal lug and
self-tapping screw must be stainless steel.
Make sure the lug terminal is placed between the wire and module frame. The wire must fully clamped with the lug terminal and must make good contact
with the frame.
There are two drill holes in the solar modules for this purpose, which are marked with a ground connection (Earthing hole 4mm) (Figure 12). The proper
torque values should be between 1,5 to 2Nm.
The photovoltaic system will be earthed according to the local and national regulations.
All the cables used in the installation must be secured in order to prevent movements that could cause damage or breakages.
ATERSA supplies a Clamp for the installation and guiding of these cables.
The Hook Clamp greatly assists the task of guiding and securing the connection cables along the length of the aluminium frame.
The Hook Clamp can be used on both the Hook V1 and Hook V4 profiles.
ATERSA solar modules hardly require any maintenance. It is sufficient to regularly check that dirt has not accumulated on the glass of the panel. Should this
be the case, clean the glass with a sponge and soapy water. Never use abrasive products that could damage the glass. Do NOT use water jet cleaning
systems. Do not clean the panels at their hottest (midday).
Check the cables and electrical connections. Check that the mechanical components are not damaged.
Maintenance work should be carried out by qualified personnel, as it could involve working with dangerously high voltages.
Our solar modules are made from high-efficiency square cells that are capable of producing power with low solar radiation. All the models from 70W to
310W have by-pass diodes in the junction box.
The technical characteristics of the modules are shown in the attached table and grapichs.
ATERSA guarantees the power output for up to 25 years and provides a 10-year warranty covering manufacturing flaws.
The modules comply with IEC 61215:2005 and IEC 61730 standards, in addition to being manufactured under strict UNE-EN ISO 9001:2008 and UNE-EN
ISO 14001:2004 quality standards.
The modules 6” 6x10 and 6” 6x12 are also certified by UL 1703.

*Note:
The cable must fulfill the requirements to be used in photovoltaic systems. The cable used by ATERSA in its modules is for outdoors use, UV resistent,
double isolation layer, 1kV, working temperature range -40ºC to 110ºC.
It is not recomended to connect modules in series with a total Voc higher than the system Vmax shown at the module label.

The correct placing of it is the one shown in figure:
According to the norm IEC 61730-1, the application class for this product (ATERSA module) is class A, which corresponds to modules working in voltages
above 50V or powers above 240W where the access to a general contact is forecasted. The modules clasified for security within this category fulfill the
requirements for ClassII.
