Considerations
Before performing maintenance on the FAC-2100
...
controller,
...
be
...
sure
...
to
...
disconnect
...
all
...
power
...
sources
...
(including
...
main
...
power
...
and
...
power
...
signals
...
from
...
analog,
...
digital,
...
communications,
...
and
...
relay
...
connections).
...
While
...
operating,
...
the
...
FAC-2100
...
unit
...
must
...
have
...
its
...
case
...
connected
...
to
...
a
...
safety
...
ground.
...
Touching
...
an
...
ungrounded
...
case
...
may
...
result
...
in
...
an
...
electrical
...
shock.
...
Also,
...
be
...
aware
...
that
...
instrumentation
...
connected
...
to
...
AC
...
or
...
DC
...
power
...
sources
...
may
...
still
...
have
...
power
...
even
...
though
...
the
...
unit
...
is
...
not
...
on.
...
This
...
unit,
...
depending
...
on
...
its
...
configuration,
...
contains
...
up
...
to
...
four
...
fuses.
...
Remove
...
all
...
power
...
sources
...
before
...
inspecting
...
or
...
changing
...
the
...
fuses.
...
Ensure
...
all
...
environmental,
...
mechanical,
...
and
...
electrical
...
limits
...
are
...
not
...
exceeded
...
during
...
operation,
...
storage,
...
and
...
transportation
...
of
...
the
...
controller.
...
Failure
...
to
...
do
...
so
...
may
...
result
...
in
...
damage
...
or
...
reduced
...
lifetime
...
of
...
the
...
device.
...
This
...
device
...
should
...
be
...
installed
...
and
...
serviced
...
by
...
qualified
...
personnel
...
only.
...
Always
...
remove
...
all
...
power
...
sources
...
before
...
installing
...
the
...
device
...
or
...
opening
...
any
...
access
...
panels
...
on
...
the
...
FAC-2100
...
.
...
Failure
...
to
...
do
...
so
...
may
...
result
...
in
...
serious
...
injury
...
and/or
...
equipment
...
damage.
...
Care
...
should
...
be
...
taken
...
when
...
touching
...
the
...
controller's
...
all-metal
...
enclosure
...
in
...
high
...
temperature
...
environments.
...
Be
...
aware
...
that
...
the
...
enclosure
...
temperature
...
may
...
be
...
in
...
excess
...
of
...
85
...
degrees
...
Celsius.
...
The FAC-2100
...
is
...
constructed
...
with
...
circuit
...
boards
...
containing
...
static-sensitive
...
electrical
...
components.
...
All
...
maintenance
...
on
...
these
...
boards
...
must
...
be
...
performed
...
using
...
standard
...
static-electricity
...
practices.
...
Always
...
use
...
a
...
grounded
...
wrist
...
strap
...
when
...
manipulating
...
these
...
parts
...
and
...
only
...
place
...
the
...
boards
...
on
...
static-free
...
surfaces.
...
Always
...
use
...
static-free
...
bags
...
if
...
transporting
...
these
...
circuit
...
boards
...
(while
...
not
...
in
...
the
...
FAC-2100
...
).
