A Warning and Safety Instructions
Service may only be carried out by qualified electricians and in keeping
with the appropriate safety regulations.
All applicable guidelines, accident prevention rules and laws must be
observed.
Before service or repair work can be started, all cables carrying power
must be safely disconnected.
Even when the appliance is disconnected from power, elements may
carry voltage.
A general visual check must be performed at all times.
A touch current measurement must be conducted on all conductive parts
that are not connected to ground.
Wear protective gloves and use the edge protection (mat. no. 5057680) to
prevent cuts by sharp edges.
