is
a Safety Class
I
instrument (pro-
vided with
a
protective earth terminal).
BEFORE APPLYING POWER

is
set
to
match the available
line voltage and the correct fuse is installed.
SAFETY EARTH GROUND
An uninterruptible safety earth ground must be
provided from the main power source
to

uct input wiring terminals, power cord, or supplied
power cord set.

The WARNING sign denotes
a
hazard. It calls attention to a
procedure, practice, or the like, which,
if
not cor-
rectly performed
or
adhered
to,
could result in per-
sonal injury.
Do
not proceed beyond
a
WARNING
sign until the indicated conditions are
fully
under-
stood and met.
The CAUTION sign denotes
a
hazard. It calls attention
to
an
operating procedure, practice, or the like, which,
if
not correctly performed or adhered
to,
could result
in
damage
to
or destruction of
part
or
all
of the
product.
Do
not proceed beyond a CAUTION sign
until the indicated conditions are fully understood
and met.
I
WARNING
1
Interrupting
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 sufficient protection).
Whenever
it
is
likely that
the
protection has been
impaired,
the
instrument
must
be made inopera-
tive and be secured against any unintended
operation.
If
this
instrument
is
to be energized via an auto-
transformer (for voltage reduction), make sure the
common terminal
is
connected to the earth termi-
nal of
the
power source.
Servicing instructions are
for
use by
service-trained personnel only.
To
avoid dangerous
electric shock, do not perform any servicing unless
qualified to do
so.
Adjustments described
in the
manual are per-
formed with power supplied to the instrument
while protective covers are removed. Energy avail-
able at many points may,
if
contacted, result
in
per-
sonal
injury.
Capacitors inside the instrument may still be
charged even
if
the instrument
has
been discon-
nected from its source of supply.
For
continued protection against fire hazard, re-
place
the
line fuse(s) only with
250V
fuse(s) of the
same current rating and type (for example, normal
blow, time delay, etc.).
Do
not use repaired fuses
or
short-circuited fuseholders.
