Centrifuges
2-2
Single phase RC12BP™ Centrifuges are equipped with a three-wire
cord with three-prong connector to fit a NEMA 6-50P (50A, 2-pole
and earth, 1Ø) receptacle, or, on 230V 50Hz centrifuges, a CEE-17
(63A, 2-pole and earth, 1Ø) receptacle. 230V 50Hz polyphase
RC12BP™ Centrifuges are equipped with a four-wire cord with five-
pin connector to fit a CEE-17 (32A, 3-pole, neutral and earth, 3Ø)
receptacle. This cord may be changed to meet local electrical code
requirements; the green and yellow wire is the ground and must be
connected to the centrifuge frame.

Location
NOTE The
RC12
BP™ is to be installed in a Pollution Degree 2
environment at an altitude not exceeding 2000 meters
(6560 feet), and is a Class A product not intended for
home use (operation in a domestic environment could
cause radio interference).
Locate the RC12BP™ on a level floor. For the centrifuge to function
properly, ambient temperature and air circulation are very important.
To ensure free air circulation, the centrifuge must be positioned so that
no air vents are blocked, allowing for its physical size (see figure 2-
2) plus an additional 15 cm (6 inches) on each side, and a minimum
of 5 cm (2 inches) behind the centrifuge (10 cm [4 inches] or more is
desired).
Ambient air temperature at the centrifuge air inlets must be between
5°C to 40°C (41°F to 104°F), with relative humidity ≤90% non-
condensing, for the centrifuge to operate. Ideal ambient temperature
to meet all performance specifications is between 20°C to 35°C (68°F
to 95°F), therefore, avoid areas near heat sources (for example,
heating pipes and radiators). Also, avoid close grouping of centri-
fuges or other heat-producing laboratory equipment. Generally, the
cooler the location, the better the operating conditions will be for the
centrifuge.

Locate the centrifuge on a
level floor to avoid rotor imbalance
during operation.
