Safety
precautions
ATTENTION
:
Please
ensure
the
correct
connection
of
the
sockets
and
sleeves
The
strings
(+
and
–
cables)
are
fed
into
the
inverter
and
connected
to
the
DC
solar
inputs.
The
module
socket
are
marked.
The
cable
on
the
+
socket
of
the
module
should
be
connected
to
the
inverter
at
the
+
input.
The
same
procedure
applies
to
the
–
socket
and
–
input.
The
cables
can
be
laid
in
cable
grooves
in
the
cross
profiles.
Here
it
is
important
to
make
sure
that
no
water
remains
in
the
cable
grooves,
e.g.
if
the
roof
is
uneven.
If
necessary
drain
holes
can
be
drilled
into
the
groove.
Only
certified
socket
connectors
are
approved
for
connecting
the
solar
cables
to
the
modules
or
inverters
respectively.
The
socket
connectors
are
crimped
on
with
special
pliers
or
connected
to
the
modules
and
inverters
with
adapter
cables.
The
adapter
sets
are
connected
to
the
(approximately
6
mm
stripped)
end
of
the
cable.
Now
establish
the
crimp
connection
and
shrink
‐
fit
the
shrink
tubing
over
the
connection
with
a
hot
‐
air
gun
or
flame.
The
individual
strings
can
be
checked
for
polarity
and
voltage
with
a
multi
‐
meter
/
voltmeter.
The
inverters
should
be
connected
in
accordance
with
the
manufacturer’s
instructions.
ATTENTION
:
Depending
on
yield
and
inverter,
different
string
lengths
are
possible.
It
is
essential
to
observe
the
assembly
instructions
and
connection
specifications
for
the
inverter!
Prior
to
connecting
to
the
inverter
check
that
each
of
the
individual
strings
is
de
‐
energised.
It
is
absolutely
imperative
that
the
inverter
be
connected
to
the
public
power
supply
network
by
a
certified
specialist.
ATTENTION
:
High
direct
current
voltage
accrues
even
at
low
levels
of
radiation.
Never
touch
unprotected
+
and
–
cables
that
are
in
operation.
6.3
Earthing
Proper
earthing
on
the
module
frames
is
the
responsibility
of
the
solar
installer
or
installation
company.
If
an
external
lightning
protection
system
is
already
provided
or
planned
for
the
building,
the
photovoltaic
system
must
be
integrated
into
the
protection
concept
against
direct
lighting
strikes.
When
using
transformer
‐
less
inverters,
earthing
should
be
carried
out
for
personal
safety
reasons.
The
earthing
point
is
marked
on
the
module
frame.
For
earthing
purposes,
an
M4
screw
is
prescribed.
Also
observe
the
national
standards.
7.
Cleaning
/
maintenance
As
the
operator,
you
should
regularly
remove
dirt
from
the
modules.
The
following
points
should
be
noted:
Never
stand
on
the
module
surface.
Do
not
exert
any
mechanical
loads
on
the
modules.
Do
not
clean
with
water
if
there
is
a
risk
of
frost
or
major
differences
in
temperature
between
the
module,
water
and
air.
We
recommend
decalcifying
hard
water.
This
will
prevent
lasting
water
stains.
Remove
standing
water
from
the
module.
Do
not
use
abrasive
cleaning
agents
or
tensides.
Do
not
scrape
off
dirt
as
this
may
damage
the
surface
of
the
module.
ATTENTION
:
Please
make
sure
that
the
earth
connection
is
not
interrupted
or
damaged!
