Safety Considerations
SAFETY CONSIDERATIONS
GENERAL
This product and related documentation must be
reviewed for familiarization with safety markings
and instructions before operation.
This product is a Safety Class I instrument (pro-
vided with a protective earth terminal).
BEFORE APPLYING PDWER
Verify that the product is set to match the avail-
able 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 the prod-
uct input wiring terminals, power cord, or sup-
plied power cord set.
Any interruption of the protective
(grounding) conductor (inside or outside
the instrument) or disconnecting thepro-
tectiwe earth terminal will cause apoten-
tial shock hazard that could result in
personal injury. (Grounding one conduc-
tor of a two conductor outlet is not suffi-
cientprotection.) In addition, verify that
a common ground exists between the
unit under test and this instrumentprior
to energizing either unit.
Whenever it is likely that theprotection
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 auto-transformer (for voltage reduc-
tion) make sure the common terminal is
connected to neutral (that is, the
grounded side of the mains supply).
Servicing instruction are for use by
service-trained personnel only. To auoid
dangerous electricshock, do not perform
any servicing unless qualified to do so.
Adjustments described in the manual
are performed with power supplied to
the instrument while protective covers
are removed. 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 fire
hezard, replace the line fuse(s) only with
25OV
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.
SAFETY SYMBOLS

hazard. It calls attention to a
procedure, practice, or the like,
which, if not correctly performed
or adhered to, could result in per-
sonal injury. Do not proceed be-
