1-5. 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.
