Electrical Installation

WARNING



Protect yourself against the danger of an
electric shock by wearing suitable protective
clothing and following the relevant regula-
tions.



Do not alter the connecting cables and con-
nectors of the module. Doing so avoids the
danger of an electric shock and upholds the
conditions of the manufacturer warranty.



Only use approved components and tools for
connecting a module string to the inverter.



All cabling should be done according to the
applicable regulations. Ensure that all con-
nections are in a flawless mechanical and
electrical condition.



Check that the cover of the junction box is
firmly attached.

8.1.

Order of work steps

For a safe and time-saving electrical installation process, aleo
solar recommends carrying out the work steps in the following
order:



connect the modules into strings



if applicable, parallel connect module strings



lay the cables to the inverter



install the inverter



connect the isolator to the inverter



connect the fire prevention switch to the isolator



connect the cables to the generator side



close the fire prevention switch and the isolator

8.2.

Series connection

Solar modules are usually connected in a row (series) in order
to create a module string.

String diodes are not necessary when modules are only
connected in series at a given inverter input.

8.3.

Wiring

aleo solar normally delivers its modules with firmly installed
junction boxes and flexible connection cables with pre-
installed connectors and sockets.

NOTICE



Avoid tensile as well as pressure loads on the
junction box during installation.



This may cause damage to the cable entry
points and affect the service life.



Also avoid excessive tensile loads to the pre-
assembled plug connections during installation.



In plug connections without locks this can lead
to loosening or detachment of the plug
connections.



In plug connections with locks this can, in
extreme cases, lead to loosening or detach-
ment of the crimp.



This can cause increased transition resistance,
heat build-up, and fire hazards.

Observe the laying regulations for the respective cable types.
Lay all cables in such a way that:



you comply with the minimum bending radii (e.g.
the 15-fold cable diameter)



close proximity to sharp corners and edges is
avoided, or the cables are correspondingly
protected



cables with differing voltages, such as the positive

⊕

and the negative

⊖

connection of a module

string do not rub against one another



module string cables have a sufficient distance
from earth, potential equalisation, and lightning
conductors



all cables run as close to one another as possible in
order to minimise the inductive area and, accor-
dingly, the effects of a lightning strike or stray
current (see also Ch. 5.12.2, 'Wiring and lightning
protection').

Carefully lay the wiring to protect the laid cables from
damages caused by:



direct environmental influences, such as
precipitation



movements through direct environmental
influences, such as wind



indirect environmental influences, such as snow or
ice that can slip behind the modules.
