5.5.1
Remove
the
Inverter
The
PVI
6500/7500
inverter
is
designed
to
be
easily
separated
from
the
wiring
box
and
removed
from
the
mounting
bracket.
You
must
wait
for
at
least
five
(5)
minutes
for
system
to
discharge
after
DC/AC
disconnect
switch
and
breakers
are
switched
OFF
and
locked
out
before
opening
the
front
cover
of
the
inverter
to
disconnect
the
wires.
Verify
the
absence
of
voltage
with
a
voltmeter.
Both
DC
and
AC
wires
that
are
disconnected
from
the
inverter
must
be
properly
terminated
with
insulating
means.
After
the
inverter
is
removed
from
the
mounting
bracket,
the
holes
that
the
wires
on
top
of
the
wiring
box
go
through
must
be
covered
with
the
cover
plate
that
is
attached
at
the
back
of
the
wiring
box
to
prevent
the
box
from
water
intrusion,
as
shown
in
the
figure
5.5.1.7.
WARNING!
PV
arrays
will
be
energized
when
exposed
to
light.
Cover
the
arrays
with
opaque
material
during
installation
and
wiring.
Verify
the
absence
of
voltage
with
a
DC
voltmeter.
WARNING!
Reconfirm
that
the
circuit
breaker
to
the
main
utility
is
switched
OFF
and
locked
out
before
disconnecting
the
power
cable
from
the
breaker
to
the
AC
terminal
block.
Verify
the
absence
of
voltage
with
an
AC
voltmeter.
