1. ESD=electrostatic discharge
As the single electronic interfaces are not protected internally against statical electricity and are
partially open, you must pay attention to that, in case of a repair, there will be a potential
compensation via the housing of the appliance (touch it) in order to neutralize a possible
charging and to prevent a damaging of the affected electronic interface.
You also have to be careful with those electronics delivered as spare parts, which have to be put
out of the ESD protective package only after a potential compensation (discharge of possible
statical electricity).
If a potential compensation with an existing static electricity is not executed, it does not mean
that the electronic is demaged directly. Consequential damages may result due to the damaging
of internal structures which arise only in case of load through temperature and current.
Endangered are all assembly groups which are provided with control entries, wire paths lying
open and free-accessible processors.

Connections instructions:
Care should be taken with regard to the two right connections that when making a replacement, the
non-occupied connections must also be tightened using a screwdriver (for induction hobs with 3
cooking zones).

The carrier plate can be removed after all of the screws have been removed and the earthed
conductor disconnected.

Appliance access instructions:
Ensure the correct spare parts numbers when replacing the filter board. The filter, electronics,
configured left, has a differnet spare parts number than the right one. The plug-in force of
disconnected plug-in connections are also to be taken into account, i.e. if the plugs are inserted too
lightly, there is a risk of plug burnout. The wiring should also be replaced if the plug area of the
defective filter module should show signs of burnout stages.
