WARNING:
If
the
GFDI
fuse
blows
upon
connection
of
one
or
more
combined
strings,
a
ground
fault
in
the
array
must
be
located
and
eliminated
before
proceeding.
The
DC
ground
fault
is
eliminated
when
the
GFDI
fuse
can
be
replaced
and
remains
intact.
Failure
to
obey
these
instructions
may
cause
the
grounded
conductor
to
rise
to
potentially
unsafe
voltage
levels.
WARNING:
Even
when
the
DC
disconnect
switch
is
in
the
off
position,
the
ungrounded
DC
conductor
leading
up
to
the
DC
disconnect
switch
will
remain
energized
on
the
PV
side
as
long
as
the
PV
modules
are
in
daylight.
The
inverter
side
of
the
DC
disconnect
switch
will
also
remain
energized
after
the
disconnect
switch
has
been
shut
off
until
60
seconds
after
the
LEDs
turn
off,
as
the
DC
bus
capacitors
in
the
inverter
discharge.
