6.5.1 Safety Information
Danger of death due to electric shock!
Before commencing any work on electrical equipment, always
unplug the mains cable from the electrical socket!
Any work and/or repairs to the electrical equipment may only be
carried out by the Burmeier service engineers, the drive
manufacturer or qualified and authorised electricians in compliance
with all the relevant VDE and safety regulations!
On no account should the user attempt to rectify malfunctions in the
electrical system!
The bed must be in the home position (with the mattress base
horizontal) in order to remove the control unit and the drives.
Otherwise, there is a danger of crushing due to parts of the mattress
base falling.
The components (control unit, drives, handset, control panel, locking
box) of the electrical system are maintenance-free and must not be
opened.
If a malfunction occurs, the relevant component must be replaced
in its entirety!
When replacing individual components, make sure that the plugs
have undamaged O-rings (for sealing) and are pushed into the
control unit as far as they will go. This is the only way to ensure proper
sealing and faultless operation.
Do not switch the motor connections at the control unit. This can
lead to malfunctions or even result in mechanical damage to the
drive due to the system not switching off at the end position.
The component plugs are connected to the corresponding control
unit.
To prevent the plugs from being inadvertently disconnected, they
are secured with a locking comb. This device can be carefully lifted
off using a screwdriver if necessary.
The ports of the control unit should be lightly lubricated with Vaseline
for the “Extended” version.
The plugs can then be inserted more easily and the O-rings provide a
better seal. The locking device should always be properly fastened.
