Safety instructions
3.6.1
Electrical safety
As protection against electric shock, the centrifuge is equipped with an
earthed mains power cable and connector. To ensure the effectiveness of
this safety feature, the following must be ensured:
DANGER
• Ensure that the wall socket is properly wired and grounded.
• Check that the mains voltage agrees with the nominal voltage listed on
the name plate.
• Ensure that the mains power cable is intact prior to using the
centrifuge. Damaged or faulty mains power cables must be replaced
immediately.
• Do not place vessels containing liquid on the centrifuge lid or within
the safety distance of 30 cm around the centrifuge. Spilled liquids may
get into the centrifuge and damage electrical or mechanical
components.
• Only qualified and specialised personnel are authorised to perform
service tasks or repairs of the electrical system for which the housing
needs to be removed.
• Inspect the electrical equipment of the unit regularly. Defects such as
loose or burnt cables must be eliminated immediately.
• Following the completion of any type of repair or service, the qualified
and specialised personnel must perform final inspection and testing in
compliance with the relevant standards.
