These specifications for the electrical connection and the standards quoted apply for connecting the
machine in EU states. It may be necessary to also observe additional specific national regulations. Outside
the EU states acceptance of the standards quoted is to be checked by the legal or natural person who
wishes to use the machine.
The local electrical plant must be constructed according to IEC 364. To improve safety, the coffee machine should be
fitted with an FI 30 mA earth leakage current circuit breaker complying with EN 61008. Near the machine or about 30
cm below the counter top there should be a shockproof socket as a single-phase connection installed locally on the
rear or side wall of the counter substructure or a nation-specific single-phase socket and, in the case of a 3-phase
connection, a 5-pin CEE/CEKON-socket according to EN 60309 or a nation-specific multi-pin socket. If the mains
connection lead for this coffee machine is damaged then it must be replaced by our customer service personnel or a
similarly qualified person. If the coffee machine is permanently connected to the mains then an all-pole disconnecting
separator (mains switch) according to EN 60947 with a minimum 3 mm contact gap must be installed. A separator
switch is recommended for a flexible connection. The mains cable must not come into contact with hot surfaces. The
mains switch and plug top are part of the customer's on-site installation. The machine may not be fitted with a fixed
permanent mains connection if installed on a transporting trolley (a mobile station).
In order to avoid possible faults from arising on our screened data lines due to potential equalization currents
between the devices, an additional potential equalization unit should be planned for devices connected to the
accounting system. (See EN 60309)

For operating, service and safety reasons the machine should
be installed with a clearance of not less than 50mm at the
back and sides from the building or non-WMF components.
A clear height of 100 mm from the top of the supporting
surface should be ensured. Recommended height of the
working surface is a minimum of 850 mm from floor level .
If the machine connections should be passed downwards
through the counter please make space for the lines which
can reduce the usable space below the machine.
Maximum diameter of 270 mm, height 670 mm
additional space needed for connecting hoses
