6.5 REPLACEMENT OF ELECTRICAL COMPONENTS
Danger of death due to electric shock!
• Before commencing any work, unplug the power adapter from the
mains socket!
• Any work and/or repairs to the electrical equipment may be carried
out only by Burmeier’s customer service, the drive manufacturer or
qualified and authorised electricians in compliance with all the
relevant VDE and safety regulations!
• The bed must be in the home position (with the mattress base
horizontal) in order to remove the control unit and the electric drives.
Otherwise, there is a danger of crushing due to mattress base
sections falling.
• On no account should the user attempt to rectify malfunctions in the
electrical system!
• When replacing individual components, make sure that the plugs
have undamaged O-rings and are inserted into the control unit as far
as they will go.
• The yellow sealing ring on the plug must be fully encompassed by
the plug coupling.
• Attention! Do not use force. If it is not possible to insert the plugs,
turn these around through 180° and insert them again.
• This is the only way to ensure a proper seal and faultless operation.
- All drive components are maintenance-free and must not be opened. In
the event of a malfunction, the corresponding components should
always be replaced in full!
- When replacing individual components, always make sure that all plugs
are equipped with undamaged O-rings. Plugs must be aligned with the
sockets on the control unit and must be inserted properly. Finally, the
plug cover has to be properly fastened again. This is the only way to
ensure a proper seal and faultless operation.
6.5.1 Plug assignment on the control unit
All plugs are connected to the control unit. To prevent the plugs from being inadvertently
disconnected, they are secured with a plug cover. Before replacing a plug, lift this cover
carefully using a screwdriver.
