Repair
and
Maintenance
The
inverter
contains
no
user
serviceable
parts.
Only
Solectria
Renewables
personnel
are
authorized
to
carry
out
internal
repair
and
maintenance
of
the
unit.
Please
return
the
device
for
repair
and
maintenance.
For
maintenance
and
replacement
of
the
fuses
by
qualified
personnel,
please
refer
to
section
5.3.
WARNING!
Do
not
make
alterations
or
tamper
with
components
in
the
inverter
without
the
manufacturer’s
authorization
unless
specified
elsewhere
in
this
manual.
They
may
result
in
injury,
electric
shock,
or
fire
and
void
the
warranty.
Wiring
the
inverter
Input/Output
Terminals:
Use
90°C
(194°F),
#10
AWG
to
#6
AWG
copper
wire
for
DC
connections
and
#10
AWG
to
#6
AWG
copper
wire
for
AC
connections.
Use
only
solid
or
stranded
wire
but
not
fine
‐
stranded
wire.
Reconfirm
that
all
connections
have
been
performed
properly
and
all
screws
are
properly
tightened
and
torqued.
WARNING!
All
electrical
installations
and
the
associated
wiring
shall
be
done
in
accordance
with
the
local
and
national
electrical
codes
and
should
follow
the
important
safety
instructions
in
this
manual.
WARNING!
Make
sure
that
you
use
suitable
connecting
conductors
for
both
the
AC
and
DC
wiring.
The
conductors
must
be
adequately
sized
and
suitably
specified
for
temperature
extremes,
UV
radiation
and
other
possible
hazards.
Connection
of
the
AC
conductors
WARNING!
Reconfirm
that
the
circuit
breaker
to
the
utility
/
breaker
panel
is
switched
OFF
and
locked
out
before
connecting
the
conductors
from
the
breaker
to
the
AC
terminal
blocks.
Connection
of
the
DC
conductors
CAUTION!
Identify
the
polarity
of
DC
voltage
on
each
PV
string
and
connect
respectively
to
the
input
terminals
marked
“UNGROUNDED
CONDUCTOR”
and
“GROUNDED
CONDUCTOR”.
Make
sure
the
DC
voltage
generated
by
the
PV
array
is
equal
or
less
than
600
VDC
factoring
in
open
circuit
extreme
cold
temperature.
WARNING!
Protect
the
DC
conductors
to
the
inverter
from
all
possible
hazards
that
could
damage
the
wires.
WARNING!
Hazardous
voltage
is
still
present
on
the
device
after
disconnection
of
all
PV
DC
inputs.
Allow
5
minutes
for
the
inverter
to
discharge
the
stored
energy
completely.
Verify
absence
of
voltage
with
a
DC
voltmeter.
WARNING!
PV
arrays
will
be
energized
when
exposed
to
light.
Cover
the
arrays
with
opaque
materials
during
installation
and
wiring.
