arnings
and
Cautions
P
ay
attention
to
W
ARNINGS
and CA
UTIONS. They
must be
followed for
your protection
and to
avoid
damage
to
the
equipment.
Before
Applying P
ower
Caution
V
erify
that
the
instrument
is
set
to
match
the
available
line
(mains)
voltage
and
that
the
correct
fuse
is
installed.
An
uninterrupted
safety
earth
ground
must
be
provided
from
the
main
power
source
to
the
instrument
input
wiring
terminals
or
power
cable
.
Warning
Maintenance
described
herein
is
performed
with power
supplied to
the
instrument
and
with
protective
covers
removed.
Such
maintenance
should
be
performed
only
by
service-trained
personnel
who
are
aware
of
the
hazards
involved
(for
example,
re and
electrical shock).
Where
maintenance
can
be
performed
without
power supplied,
the power
should
be
removed.
Any
interruption of
the
protective
(grounding)
conductor
(inside
or
outside
the instrument)
or
disconnecting
the
protective
earth
terminal
will
cause a
potential
shock
hazard
that
could
result
in
personal
injury
.
(Grounding
one conductor
of
a
two
conductor
outlet
is
not
sucient
protection.)
In
addition, verify
that
a
common
ground
exists
between
this
instrument
and
the
test
equipment
prior
to
energizing
either
unit.
Whenever
it
is
likely
that
the
protection
has
been
impaired,
the
instrument
must
be
made
inoperative
and
be
secured
against
any
unintended
operation.
If
this
instrument
is
to
be
energized
via
an
autotransformer
(for voltage
reduction)
make
sure
that
the
common
terminal
is
connected
to
neutral
(that
is
,
the
grounded
side
of
the
mains
supply).
Servicing
instructions
are
for
use
by
service-trained
personnel
only
.
T
o
avoid
dangerous
electric
shock,
do
not
perform
any
servicing
unless
qualied
to
do so
.
Energy
available
at
many
points
may
,
if
contacted,
result
in
personal
injury.
Capacitors inside the instrument may still be charged even if the
instrument has
been disconnected from its source of supply
.
For continued
protection against re hazard, replace the line fuse(s)
only with 250 V
fuse(s) of the same current rating and type (for example
normal blow
, time
delay, etc.). Do not use repaired fuses or short
circuited fuse holders
.
