Caution: Electric drive system
With its wide variety of functions, the electrically powered nursing care bed provides the
patient with substantial physical and emotional support for their recovery process, while
also alleviating pain. As medical devices, electrically powered beds require a high level of
diligence with regard to regular safety inspections. This includes safe use of the nursing
care bed, daily inspection of electrical equipment, and proper cleaning and mainte-
nance.
To avoid cable damage, cords and cables should be placed outside of any area where dam-
age could occur. Any contact with sharp-edged components should also be prevented. To
avoid risk of injury from electric shock, any possibility of excessive touch voltage should
be eliminated. Such circumstances are especially likely to occur when the mains power
cable has been damaged, when dangerous and excessive leakage currents are present, or
when liquid has entered the motor housing, e.g. as a result of improper cleaning. Such
damage can result in control unit malfunction which can in turn lead to unintended move-
ments of individual bed components, raising the risk of injury to patients and users.
