7.1.1 Emergency lid release
In the event of a power failure, it is possible to manually open the centrifuge
lid.
• Switch off the mains power switch and disconnect the power cord from
the socket.
• Remove the plug (see figure, item 1) from the front panel, e.g. with a
screwdriver.

turn it anti-clockwise to the stop. The lid lock will then audibly unlock.

• Then, reinsert the plug.
Do not unlock or open the lid unless the rotor is at a standstill.
If the lid is opened via the emergency lid release system during a centrifuge
run, the centrifuge will be switched off immediately and decelerate in an
unbraked manner.
