To ensure optimal safety, the centrifuge should be wired to a remote emergency switch (preferably
outside the room where the centrifuge is housed, or adjacent to the exit from that room). In case of
a malfunction, the centrifuge can be disconnected from the main power source by removing the
Mains (power) plug from the outlet receptacle.
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.
Prior to instrument purchase, the power configuration should be determined and the appropriate
instrument ordered.
