Specifications and Preinstallation Requirements
for power and site preparation have been met. The following equip-
ment is required for preinstallation:
• Voltmeter
• For single phase centrifuges: two 30-ampere circuit breakers
• For three phase centrifuges: three 16-ampere circuit breakers
• Power receptacle (see Figure 1-1 or 1-2)
• Drill for drilling holes in the floor for installation of anchoring kit
bolts (see
SECURING THE CENTRIFUGE TO THE FLOOR
, later
in this section). A 9.5 mm (
3
/
8
-inch) drill is required for concrete
floors. A 6.4 mm (
1
/
4
-inch) drill is required for wood floors.
ELECTRICAL REQUIREMENTS
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 that there are
properly rated thermal circuit breakers at the 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 (for single-phase centrifuges) or greater than 16 amperes
(for three-phase centrifuges).
Terminate the open end of the harmonized cord with a certified
single- or three-phase connector suitable for the power supplied in the
country of intended use (see Table 1-1). Install only one centrifuge
per circuit.
To ensure safety, connect the instrument to a remote emergency
switch (preferably outside the room where the centrifuge is housed,
or adjacent to the exit from that room), to disconnect the centrifuge
from the main power source in case of a malfunction.
