WARNING
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.
Prior to instrument purchase, the power configuration should be
determined and the appropriate instrument ordered.
