WARNING
The following instructions are for use by qualified
personnel only. To avoid electric shock, do not per-
form servicing other than contained in the operating
instructions unless you are qualified to do so.
SAFETY
Before
connecting
the
instrument
to
a power
source,
carefully read the following
information,
then verify that
the proper power cord is used and the proper line fuse is in-
stalled for power source.
If the power cord is not applied
for specified voltage, there is always a certain amount
of
danger from electric shock.
Line voltage
This instrument
operates
using ac-power
input voltages
that
100/120/220/240 V at frequencies from
50 Hz to
60 Hz.
Power cord
The ground wire of the 3-wire ac power
plug places the
chassis and housing of this instrument at earth ground. Do
not attempt to defeat the ground wire connection or float
this instrument; to do so may pose a great safety hazard.
The appropriate power cord is supplied by an option that is
specified when the instrument is ordered.
Waming
If groundings, especially points | (Vg) and ¥ (Ig), are short-
circuited during servicing, it could lead to pattern damage
due to large amount of current flow on the PCB. Take ap-
propriate care.
