6.1 Wipe-down disinfection
Switching off the power supply
Contact with live parts may result in electric shock.
• Before cleaning and disinfection, the permanently connected
ME device must be disconnected from all phases of the power
supply grid. The ground conductor connection (PE) must
remain intact.
• It must be possible to lock the power supply disconnector in
the off position.
• For ME devices that are not permanently connected and have
no power supply main switch, a suitable plug device to
disconnect the ME device from the power supply grid will meet
this requirement.
• Separate all electrical phases of these components according
to Chapter 5.7:
– Ceiling-mounted version
– Mobile pedestal version
– Lamp head or support arm system
• Ensure that no cleaning and disinfecting agents penetrate the
lamp head or support arm system.
• Do not insert objects into device openings.
Risk of fire or explosion due to disinfectants
Flammable or explosive atmospheres may be created when
handling disinfectants due to the formation of gases, vapors, or
mists.
• Do not use any highly flammable disinfecting agents.
• Do not perform any large-scale disinfections.
• Allow hot surfaces to cool prior to disinfection.
• Completely disconnect the electrical installations in the room,
where possible, and ensure that no switching can take place
while disinfecting, especially automatically.
• After wiping with disinfectant, wait until the disinfecting agent
is completely dry.
• Ensure that the room is adequately ventilated.
The disinfection procedure to be used for the lamp head, the
support arm system, the Mobile Control 7,9 and the
Wall Control Panel is wipe disinfection. The lamp head must be
cool for cleaning and disinfection.
Only clean and disinfect the surgical light system, the
Mobile Control 7,9 and the Wall Control Panel by wiping them with
a damp but not wet cloth. Apply only a thin liquid film, wipe, and
leave behind only a thin, cohesive film of moisture. This moist film
has sufficient microbiological effect. The fluid does not need to
remain on the surface.
Applying too much fluid to the surface during disinfection leaves
residue behind. This can lead to incorrect measurements,
especially on the sensor cover plate. To prevent build-up of
disinfectant residue, a mild all-purpose cleaner should be used for
