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.

Single and Three-Phase Power Connections
