Considerations
AC
Module
should
only
be
mounted
in
locations
that
meet
the
following
requirements:
Maximum
Altitude
:
AC
Modules
can
be
installed
in
locations
with
a
maximum
of
2000
meter
altitude.
Operating
Temperature:
AC
Modules
must
be
mounted
in
environments
that
ensure
that
the
modules
will
operate
within
the
following
maximum
and
minimum
temperatures:

Design
Strength:
AC
Modules
are
designed
to
meet
a
maximum
positive
(or
upward,
e.g.
wind)
and
negative
(or
downward,
e.g.
static
load)
design
pressure
when
mounted
in
the
mounting
configurations
specified
in
Table
1
and
2
for
the
details
on
load
ratings
and
mounting
locations.
AC
Modules
have
also
been
evaluated
to
IEC
61215
for
a
positive
or
negative
design
load
of
3600
Pa
with
a
1.5
Safety
Factor.
When
mounting
modules
in
snow
‐
prone
or
high
‐
wind
environments,
special
care
should
be
taken
to
mount
the
modules
in
a
manner
that
provides
sufficient
design
strength
while
meeting
local
code
requirements.
Important!
The
following
image
and
tables
show
where
to
mount
in
module
frame
and
the
allowable
load
ratings
corresponding
to
the
mounting
zones
chosen.
To
use
the
tables,
identify
the
two
mounting
zones
in
which
you
wish
to
mount.
You
may
choose
to
mount
at
any
location
in
zones
A,
B,
and
C,
as
long
as
the
mounting
points
are
symmetric
about
one
axis
of
the
module.
Identify
the
combination
of
mounting
zones
you
have
chosen
in
the
table
and
then
refer
to
the
corresponding
load
rating.
Note
also
that
load
ratings
are
different
for
modules
supported
by
rails;
versus
systems
that
attach
modules
underneath
the
module
frame
or
without
rail
support.
