Technical safety

Unauthorised installation, maintenance and repairs can cause
considerable danger for the user. Installation, maintenance and
repairs must only be carried out by a Miele authorised technician.

Damage to the hob can compromise your safety. Check the hob
for visible signs of damage. Do not use the hob if it is damaged.

Reliable and safe operation of this hob can only be assured if it
has been connected to the mains electricity supply.

The hob must not be connected to the inverter of an autonomous
power supply such as e.g. a solar power system. When the hob is
switched on, power surges could result in a safety switch-off. This
could damage the electronic module.

The electrical safety of this hob can only be guaranteed when
correctly earthed. It is essential that this standard safety requirement
is met. If in any doubt please have the electrical installation tested by
a qualified electrician.

To avoid the risk of damage to the hob, make sure that the
connection data on the data plate (voltage and frequency) match the
mains electricity supply before connecting it to the mains.
Consult a qualified electrician if in doubt.

Do not connect the hob to the mains electrical supply by a multi-
socket adapter or extension lead. These are a fire hazard and do not
guarantee the required safety of the appliance.

For safety reasons, this hob may only be used after it has been
built in.

This hob must not be used in a non-stationary location (e.g. on a
ship).
