8 Mechanical Installation
8.1 Mounting orientation for modules
8.1.1 Vertical (portrait) mounting
When mounting the module vertically, make sure that the
cables are facing towards the ground and the junction box
is facing upwards.
8.1.2 Horizontal (landscape) mounting
When mounting horizontally, make sure that the exit holes
for the cables on the module or the junction box are positi-
oned on the inside of the photovoltaic generator. Avoid the
lateral outer edges of the photovoltaic generator to minimi-
se the effect of ambient conditions, such as wind or rain.
8.1.3 Inclination
Incline the surface of the modules at an angle of at least
10° horizontally, so that precipitation can drain off which
supports the modules self-cleaning.
For optimum self-cleaning, we recommend an angle of at
least 15° horizontally. In case of flat installations is advisa-
ble the employment of our unframed modules.
NOTE
Avoid locations in which, over the course of the day
or year, there is systematic shadowing due to neigh-
bouring objects or buildings
Fig.1 Recommended position of the junction boxes for
horizontal mounting (facing the middle of the
generator)
8.2 Safety precautions
NOTE
• Do not drill any additional holes in aleo modules or
their frames.
8.3 Improper mounting
NOTE
• Do not attach the modules using nails. The vibration
created in the process can cause micro fissures and
loss of yield, and results in loss of warranty rights.
• Do not attach the modules by welding. The tempera-
tures created in the process can cause delaminati-
on, micro fissures and loss of yield, and results in
loss of warranty rights.
8.4 Intervals
8.4.1 Intervals between modules with standard frames
NOTE
• Leave a minimum clearance when mounting modu-
les. This prevents mechanical tension due to ther-
mal expansion.
• When mounting at intervals
Leave a clearance of 3 mm or more between the
individual module frames.
• For edge-to-edge mounting
Allow for an expansion joint of 20 mm aer a
maximum of 7 m.
• The recommended maximum clearance is 30 cm,
based on the modules‘ standard cable length.
aleo solar recommends mounting at intervals. Also note the
information from the mounting equipment vendor. This
could specify larger intervals.

- if the connectors have the same basic designation
(e.g. “MC4”) or
- if they are designated as “compatible”.
_______________________________________________
You can find more details on this in the next two sections.
9.1.1 Module connectors
The various module types can be fitted with the following
connectors:
 • OriginalMulticontact®MC4 (with locking)
 • PV-JM601(withlocking)
You can find the specific connectors in the module data
sheet.

9.1.3 Replacing the connectors
You can remove the connector on a module and replace it
with another connector, if necessary. You retain the manu-
facturing warranty if you remove and mount with approved
tools in the proper way and according to the connector
manufacturer‘s instructions.
1The original Multicontact® MC4 connectors are referred to as “MC4” in the data sheet.
8.4.2 Clearance under the modules
■ Minimum clearance
NOTE
 • Roooporfreeeldmounting
Ensure a clearance of at least 4 cm between the rear
edge of the frame and the mounting surface (e.g. the
roof tiles) for the rear ventilation ohe aleo module.
 • Roof-integratedmounting
Ensure an appropriate interval, for example, to the
trough of the mounting system. Also ensure ade-
quate ridge ventilation, for example, with a roof
ridge ventilator.
■ Maximum clearance
NOTE
 • Thelargestpermissible clearance is defined by
national standards. This is used to design the instal
lation on the assumed effects of wind and suction.
 • Theactual maximum clearance of an installation is
determined by the sub-structure. Ensure that your
sub-structure adheres to the permissible clearances.
8.5 Avoiding seals

 • Alsoforroof-integratedmounting,ensuregoodrear
ventilation to minimise loss of output which results
from a higher module temperature. Ensure adequa-
te ridge ventilation, for example, with a roof ridge
ventilator.
8.6 Clearance under the modules
NOTE
 • Keepthespacebehindthelaminatefreeofany
objects. This prevents damage to the insulating
back sheet and the junction box.

9.2 Laying the string cables
CAUTION!
Brittle fractures in junction boxes due to contact
with unsuitable connection cables: Risk of fire!
• Only use connection cables without plasticisers.
NOTE
• Avoid any tensile and pressure loads on the junction
box when mounting.
• When mounting, avoid heavy tensile loads on any
connectors already plugged in.
NOTE
• Bend the cables from the connector at least 4 cm
after they exit from the connector.
• Bend the cables from the junction box as well, at
least 4 cm after they exit from the connector.
• This keeps the cables waterproof at the cable outlet.
Observe the guidelines on laying the respective cables. Lay
all cables ensuring that:
• You adhere to the minimum bend radius (e.g. 5-fold
cable diameter2),
• You avoid laying near sharp corners and edges or
protect the cables accordingly
• You protect them from direct sunlight and precipi-
tation
• You secure the cables with UV resistant cable clips3
or other suitable cable fasteners which protect the
cable insulation,
• Cables from module strings are laid as near to each
other as possible to minimise the effects of being
struck by lightning
9.2.1 Weather protection
NOTE
• Lay the cables so that they exit the junction box from
below. This prevents water, which runs along the ca-
ble, from collecting at the point where the cables
exit the junction box.
• For modules mounted horizontally, lay the cables
in a U-form away from the junction box.
• Modules mounted vertically do not usually need
any additional adjustments.
Fig.2 U-form cables at the junction box for a horizontally
mounted module
Lay cables carefully to protect against damage from:
• Direct environmental factors, such as precipitation
• movement (e.g. from wind)
• Indirect environmental factors, e.g. snow or ice,
which slip down behind the modules, and
• Chaffing on the insulation due to the cable moving
(e.g. from wind or ice).
9.3 Potential equalisation (earthing) of module
frames
NOTE
• Local regulations may specify potential equalisation
(earthing).
• When earthing the module frame, establish a safe
electrical connection to the earth potential or
earthed sub-structure.
• Observe the requirements and recommendations
of the inverter manufacturer, as well as insurance
policies.
• The module frames are made of aluminium. When
mounting onto other materials, take suitable mea-
sures to prevent electric corrosion, e.g. by using a
coating.
NOTE
Potential equalization does not serve as lightning
protection. Lightning protection may be necessary
in addition to potential equalization.
2Some countries specify a larger bend radius, e.g. 8-fold wire diameter in the
USA (NEC Codebook 2011).
3For attaching the cable clip, use a suitable tool which can fully tighten at a de-
fined low force. Avoid cable clips and tools which constrict or damage the cable
insulation when tightening.

9.4 Lightning protection
WARNING!
Absence of or inadequate lightning protection.
Risk of fire or electric shock!
• Leave the planning and installation of the external,
and if required internal, lightning protection to be
carried out by qualified technicians at all times.
• It is essential to integrate an arrestor for connecting
the lightning rod with the lightning protection. This
ensures the safety and reliability of the lightning pro-
tection as well as the photovoltaic system.
• Do not under any circumstances include the module
frame or its earth as an active part of the lightning
protection (e.g. as a lightning arrestor).
NOTE
If you earth the module frame, the only task of this
earth is the potential equalisation between the mod-
ule frame and the supporting structure.
