Rear Panel Connectors
Figure 2–8 shows the rear panel of the waveform monitor. A brief discussion of
each connector follows the illustration. Again, features unique to a specific
waveform monitor are indicated in the text.
The waveform monitor is designed to operate from a single-phase power source
with the neutral conductor at or near earth ground. Only the line conductor is
fused for over-current protection. A protective ground connection through the
grounding conductor in the power cord is essential for safe operation.
WARNING.
Dangerous potentials are present on the Power circuit board. To avoid
electric shock, do not connect power to the waveform monitor if it is not enclosed
in a prescribed cabinet.
The waveform monitors operate from an AC line frequency of 50 and 60 Hz,
over the range of 90–250 VAC, without the need for configuration. Refer to the
Specifications section of this manual for additional information on power and
environmental requirements.
