WARNING
Figure 1-1 shows the power connection for single-phase centrifuges,
including earth-ground and two power leads with 30-ampere circuit
breakers. Figure 1-2 shows the power connection for three-phase
centrifuges, including earth-ground and three power leads with
minimum 16-ampere circuit breakers and common neutral connec-
tion. Table 1-2 contains wiring information.

To reduce the risk of electrical shock, this
equipment uses a three-wire or five-wire elec-
trical cord and plug to connect the centrifuge
to earth-ground. To preserve this safety
feature, make sure that the matching wall
outlet receptacle is properly wired and
earth-grounded.
