Preinstallation Requirements

Electrical Requirements

To reduce the risk of electrical shock, this centrifuge uses a permanently 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 A.2 shows the power connection.

WARNING

To reduce the risk of electrical shock, this equipment uses a three-wire or five-wire

electrical 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. Check that the line voltage agrees with the voltage

listed on the name rating plate affixed to the centrifuge.

• The Mains (power) plug is the disconnect device and must remain easily accessible.

• Position the centrifuge so that it is easy to remove the Mains (power) plug from the outlet

receptacle.

• Never use a three-to-two wire plug adapter.
