INSTALLATION (SUPPLEMENT)
1. The switching operation of this microwave oven can cause voltage
fluctuations on the supply line. The operation of this oven under
unfavorable voltage supply conditions can have adverse effects. This
device is intended for the connection to a power supply system with
a maximum permissible system impedance Zmax of 0.2 Ohms at the
interface point of the user's supply. The user has to ensure that this
device is connected only to a power supply system which fulfills the
requirement above. If necessary, the user can ask the public power
supply company for the system impedance at the interface point.
2. If there is no equipotential bonding conductor in the electric
supply, an external equipotential bonding conductor must be
installed at the rear of the appliance (see symbol). This terminal
shall be in effective electrical contact with all fixed exposed metal
parts and shall allow the connection of a conductor having a
nominal cross-sectional area up to 10 mm².
Symbol for the external connection of equipotential
bonding conductors.
