WARNING
GROUNDING. For electric shock protection, make the grounding
connection before making any connection to the instrument's input
or output terminals. This instrument is safety Class 1 equipment
(IEC designation). All accessible conductive parts are directly
connected through the grounding conductor of the power cord to
the grounded (earth) contact of the power plug.
Any interruption of the grounding connection can create an electriĆ
cal shock hazard. The power input plug must be inserted only in a
mating receptacle with a grounding contact where earth ground
has been verified by a qualified service person. Do not defeat the
grounding connection.
WARNING
AC POWER SOURCE AND CONNECTION. An improper voltage
supply can damage the instrument. The instrument operates from a
singleĆphase power source. It has a threeĆwire power cord and
twoĆpole, threeĆterminal grounding type plug. The voltage to
ground (earth) from either pole of the power source must not
exceed the maximum rated operating voltage, 250 V.
Before making connection to the power source, check that the LINE
VOLTAGE SELECTOR is set to match the voltage of the power
source and has a suitable twoĆpole, threeĆterminal groundingĆtype
plug.
