Replacement of Electrical Components
14 Replacement of Electrical Components
14.1 Safety Information
Danger of Death Due to Electric Shock!
Any work and/or repairs to the electrical equipment may only be carried out by Stiegelmeyer
service engineers, the actuator manufacturer or qualified and authorised electricians in
compliance with all relevant VDE and safety regulations!
On no account should the user attempt to rectify malfunctions in the electrical system!
Before commencing any work on electrical equipment, always unplug the mains cable from
the electrical socket!
Crushing Hazard Due to Falling Mattress Base Parts
The bed must be in the home position (with the mattress base horizontal) in order to remove the
control unit and the actuators.
Risk of Injury Due to Faulty Maintenance
The components (control unit, actuators, handset, control box, locking box) of the electrical
actuator 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 wrongly connect the motor connections at the control unit. This can lead to malfunc-
tions or even result in mechanical damage to the actuators 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 device. This
device can be carefully lifted off using a screwdriver if necessary. The locking device must
always be properly refastened.
The control unit sockets should be lightly greased inside with Vaseline. The plugs can then
be inserted more easily and the O-rings provide a better seal.
