NOTE. Read all information and heed all warnings in this subsection before
connecting the waveform monitor to a power source.
WARNING. AC POWER SOURCE AND CONNECTION. The waveform monitor
operates from a single-phase power source. It has a three-wire power cord and
two-pole, three-terminal grounding type plug. The voltage to ground (earth) from
either pole of the power source must not exceed the maximum rated operating
voltage, 240 volts.
Before making connection to the power source, be sure the waveform monitor
has a suitable two-pole, three-terminal grounding-type plug.
GROUNDING. 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 (earthing) contact of the power
plug.
WARNING. 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. Any interruption of the
grounding connection can create an electric shock hazard.
For electric shock protection, the grounding connection must be made before
making connection to the instrument's input or output terminals.
A power cord with the appropriate plug is supplied with each waveform monitor.
Table 2–1 gives the color-coding of the conductors in the power cord.
