Protective Earth (Grounding)
Protection Class 1 - The Instrument must be operated with a protective earth/ground
connection via the protective earth/grounding conductor of the ac line supply cable. The
protective earth/ground connects before the ac line and neutral connections when the
supply plug is inserted into the Instrument's rear panel ac line supply socket. If the final
connection to the ac line supply is made elsewhere, ensure that the protective
earth/ground connection is made before ac line and neutral.
If there is a possibility the protective earth/ground connection might not be made before
the ac line and neutral connections, or the output terminals are connected to a potentially
hazardous live circuit, the separate protective earth/ground connection stud on the rear
panel of the Instrument must be connected to a suitable protective earth/ground.
XWWarning
To avoid electrical shock or personal injury, do not intentionally
or unintentionally interrupt the protective ground conductor
inside or outside the Instrument. Interrupting the protective
ground conductor is likely to make the Instrument dangerous.
Intentional interruption is prohibited.
Power Cord and Power Supply Disconnection
The front-panel power switch is a remote on/off switch and does not directly disconnect
line power. The power supply disconnect device is the ON / OFF switch on the rear panel
of the Instrument. The ON / OFF switch should be readily accessible while the
Instrument is in operation. If this operating condition cannot be satisfied, it is essential
that either the power cord plug or a separate power disconnecting device be readily
reached and accessible to the operator.
