ELECTRICAL REQUIREMENTS

• Position the centrifuge so that the air diverter nearly touches the
wall behind the centrifuge. Place the power cord to one side of the
air diverter. To avoid damaging the power cord when installing or
moving the centrifuge, be sure to move the cord out of the way
before pushing the centrifuge toward the wall.
• Relative humidity should not exceed 95% (noncondensing).
200-V centrifuge . . . . . . . . . . . . . . . . 180–220 VAC, 24 A, 50/60 Hz
230-V centrifuge . . . . . . . . . . . . . . . . 207–253 VAC, 24A, 50/60 Hz
208/240-V centrifuge. . . . . . . . 187–229/216–264 VAC, 24A, 50 Hz
To reduce the risk of electrical shock, this centrifuge uses a perma-
nently attached 1.8-m (6-ft) three-wire UL/CSA approved electrical
cord and plug to connect the centrifuge to earth-ground. (Contact
your local Beckman Coulter office for specific information regarding
local plug requirements.) To preserve this safety feature:
• Power to the centrifuge should originate directly from a main
power line transformer at a power source known to be clear of
erratic loads, spikes, and electromagnetic interference. Make sure
there are properly rated thermal circuit breakers at the wall service
panel to protect the centrifuge circuit. If fuses must be used instead
of the specified circuit breakers, the fuses may require a rating of
greater than 30 amperes. Figure 2-2 shows the power connection.
