2 SAFETY
2.1 Safety warnings
Electrical hazard!
Repairs should only be carried out by the manufacturer’s technical
staff.
Inadequate repairs can harm the users.
The sheath and framework may be subjected to voltage in case of
failure.
The appliance should be disconnected from the mains before
dismounting. It contains parts inside that are subjected to high
voltage.
Electrical hazard!
Touching the terminals of power cord immediately after mains
disconnection could produce a small electric shock, this is caused by
the charged capacitors from the EMC filter included in all induction
boards (ELIN).
T
he capacitors need time for discharging over the electronic load into
the board, that time depends on the hob variant and it is between 2
and 3 seconds. That means, the voltage in the terminals will be less
than 34V (This voltage is considered not dangerous according to
EN60335) after 3 seconds and then there is not risk
.
If one module was defected (ELIN), we could have two condensators
more and the time would be 8-9 sg.
Always use a current-breaker switch if it is necessary to conduct low-
voltage tests.
The earth connection should not exceed standardised values. This is
of the utmost importance for people’s safety and normal working
conditions of the appliance.
Once the appliance has been repaired, it should be subjected to tests
VDE 0701 or the specific regulations that are in force in the country
concerned.
The replacement of the power cable can only be carried out by
authorised technical staff, using the replacement cable.
