To reduce the risk of electrical shock, this ultracentrifuge uses a three-
wire electrical cord and plug to connect the ultracentrifuge to earth-
ground. (Contact your local Beckman Coulter office for specific
information regarding local requirements.) To preserve this safety
feature:
• Make sure that the matching wall outlet receptacle is properly
wired and earth-grounded. Check that the line voltage agrees with
the voltage listed on the name rating plate affixed to the ultracen-
trifuge. Then plug in both ends of the ultracentrifuge power cord.
• Never use a three-to-two wire plug adapter.
• Never use a two-wire extension cord or a two-wire non-grounding
type of multiple-outlet receptacle strip.
• If there is any question about voltage, have a qualified service
person measure it under load while the drive is operating.
To ensure safety the ultracentrifuge should be wired to a remote emer-
gency switch (preferably outside the room where the ultracentrifuge
is housed, or adjacent to the exit from that room), in order to
disconnect the ultracentrifuge from the main power source in case
of a malfunction.
INSTALLATION PROCEDURES
Installation of the ultracentrifuge requires the following steps—in
order:
• installing the filter,
• checking the time-delay setting,
• leveling the instrument, and
• installing the brake pin and stator pad.
After installation, perform a trial run to ensure proper operation.
