Electrical installation requirements
Safety rules
Observe the following rules to prevent hazards caused by faulty electrical connections:
•
Only electricians qualified under the terms of EN 50110-1 and from an authorized service company are permitted
to perform work on electrical equipment.
•
The electrical supply must be connected in accordance with applicable local regulations of the professional
associations and of the relevant power supply company.
• The case of the appliance must be grounded in a suitable manner and connected to an equipotential bonding
system.
• If two microwave combination ovens are installed in a stacking kit, both cases of the appliances and the stacking kit
itself must be grounded in a suitable manner and connected to an equipotential bonding system.
• Wear the personal protective equipment as specified in the Section 1F .
Grounding instructions
The appliance must be grounded. Connect only to a properly grounded outlet. See ‘Grounding instructions’ in
Section 1F.
Equipment provided by customer and electrical installation regulations
Table 2.1 shows what equipment must be provided by the customer and what regulations must be observed when
connecting the appliance.
Equipment Regulations
Fuse Fuse protection and connection of the appliance must comply with local regulations and
national installation requirements.
Equipotential bonding The appliance must be incorporated in an equipotential bonding system.
Equipotential bonding: electrical connection that ensures that the frames of electrical
equipment and any external conductive components are at an equal (or practically equal)
potential.
Residual-current device
(RCD) The installation regulations require protection by a residual-current device (RCD). Suitable
residual-current devices meeting the relevant national regulations must be used.
If the installation includes more than one appliance, one residual-current device must be
provided for each appliance.
Disconnection device An easily accessible all-pole disconnection device with a minimum contact separation of 3mm
must be installed close to the appliance. The appliance must be connected via this
disconnection device. The disconnection device is used to disconnect the appliance from the
electrical supply for cleaning, repair and installation work.
