CAUTION:
This
equipment
is
designed
to
permit
the
connection
of
the
earthed
conductor
of
the
dc
supply
circuit
to
the
earthing
conductor
at
the
equipment.
This
equipment
is
designed
to
permit
the
connection
of
the
earthed
conductor
of
the
dc
supply
circuit
to
the
earthing
conductor
at
the
equipment.
If
this
connection
is
made,
all
of
the
following
conditions
must
be
met:
v
This
equipment
shall
be
connected
directly
to
the
dc
supply
system
earthing
electrode
conductor
or
to
a
bonding
jumper
from
an
earthing
terminal
bar
or
bus
to
which
the
dc
supply
system
earthing
electrode
conductor
is
connected.
v
This
equipment
shall
be
located
in
the
same
immediate
area
(such
as,
adjacent
cabinets)
as
any
other
equipment
that
has
a
connection
between
the
earthed
conductor
of
the
same
dc
supply
circuit
and
the
earthing
conductor,
and
also
the
point
of
earthing
of
the
dc
system.
The
dc
system
shall
not
be
earthed
elsewhere.
v
The
dc
supply
source
shall
be
located
within
the
same
premises
as
this
equipment.
v
Switching
or
disconnecting
devices
shall
not
be
in
the
earthed
circuit
conductor
between
the
dc
source
and
the
point
of
connection
of
the
earthing
electrode
conductor.
Statement
30:
CAUTION:
To
reduce
the
risk
of
electric
shock
or
energy
hazards:
v
This
equipment
must
be
installed
by
trained
service
personnel
in
a
restricted-access
location,
as
defined
by
the
NEC
and
IEC
60950-1,
First
Edition,
The
Standard
for
Safety
of
Information
Technology
Equipment.
v
Connect
the
equipment
to
a
reliably
grounded
safety
extra
low
voltage
(SELV)
source.
An
SELV
source
is
a
secondary
circuit
that
is
designed
so
that
normal
and
single
fault
conditions
do
not
cause
the
voltages
to
exceed
a
safe
level
(60
V
direct
current).
v
The
branch
circuit
overcurrent
protection
must
be
rated
20
A.
v
Use
12
American
Wire
Gauge
(AWG)
or
2.5
mm2
copper
conductor
only,
not
exceeding
4.5
meters
in
length.
v
Incorporate
a
readily
available
approved
and
rated
disconnect
device
in
the
field
wiring.
CAUTION:
This
unit
has
more
than
one
power
source.
To
remove
all
power
from
the
unit,
all
dc
MAINS
must
be
disconnected.
