5.2.2 Electrical connection
Danger
Electric shock from live components
A fatal electric shock can occur when the warewasher and its additional devices are connected to the elec-
trical mains supply.
Ø
The warewasher and its additional devices may be connected to the electrical mains supply only by a
specialist company registered within the electrical trade and approved by the energy supplier.
Ø
All locally applicable standards and regulations must be observed during the connection to the electrical
mains supply.
Ø
When performing installation and maintenance work as well as repairs, unplug the warewasher from the
mains supply. Check that there is no voltage present.
Ø
The electrical safety of this warewasher is guaranteed only if it is connected to a correctly installed protective circuit
and a residual current circuit breaker. It is crucial that this basic safety requirement is tested and, in case of doubt, that
the on-site installation is checked by a qualified electrician.
Ø
The circuit diagram must be observed.
Ø
The warewasher may be operated only at the voltages and frequencies specified on the rating plate.
Ø
A mains isolation switch with all-pole separation from the mains supply must be installed in the electrical feeder and
must be easily accessible. We recommend installing it near the warewasher.
Ø
The electrical connection must be secured as a separately fused circuit with slow fuses or circuit breakers. The fuse
protection depends on the total connected load of the warewasher. The total connected load is specified on the rating
plate of the warewasher.
Ø
If an on-site residual current circuit breaker is intended, we recommend installing a universal current-sensitive residual
current circuit breaker of Class B with a release current of 30 mA (DIN VDE 0664), since a frequency inverter is loc-
ated in the warewasher.
Ø
Determine the cable cross section of the mains cable using the following table:

The mains cable must be an oil-resistant, sheathed and flexible cable. The cable type H07RN-F is recommended.
