Other warning symbols where they apply.
AC POWER SOURCE AND CONNECTION
This instrument operates from a single-phase power source and has a three-wire power cord with a two-
pole, three-terminal grounding-type connector. The voltage to ground (earth) from either pole of the power
source must not exceed the maximum rated operating voltage, 250 volts.
Before making connection to the power source, a qualified service person should verify that the instrument is
set to match the voltage of the power source and has a suitable two-pole, three-terminal grounding-type
connector.
GROUNDING THE INSTRUMENT
This instrument is safety class 1 equipment (IEC* designation). Safety class 1 equipment has a 3-wire power
cord with a 3-contact plug for connection to the power source and to protective ground. The plug protective-
ground contact connects (through the cord protective-grounding conductor) to the accessible meta! parts of
the equipment. For electric-shock protection, insert this plug into a socket outlet that has a securely grounded
protective-ground contact.
For medical-dental applications (to assure grounding integrity) the hospital-grade input plug must be inserted
only into a mating hospital-grade receptacle with a grounding contact.
To confirm that the socket-outlet ground contact is securely grounded, refer to
qualified service personnel.
