Domestic Power Grounding
For safety, the power cords used on this product have a
three-wire, grounding-type power cord. Figures 2-1 and 2-
2 illustrate the appropriate electrical outlet to use with the
power cords included with 100-120 volt and 200-240 volt

is compatible with the power outlet used in many Conti-
nental European countries. Refer to Figure 2–3. However,
if your application requires another type of power cord,
check with your equipment supplier, and follow local reg-
ulations concerning proper wiring and grounding.
