16.6 Connecting the drain hose
Caution
Do not shorten or damage the hose.
Do not bend the hose when laying it.
The drain hose is located in the machine.
Connect the drain hose (A) to the machine.
Connect the drain hose to the on-site water
drain.

16.7 Electrical connection
Danger
Danger of death: live components!
The machine and the relevant additional devices must be connected by an electrical compa-
ny authorised by the relevant electricity supplier as per the locally applicable standards and
regulations.
When performing installation and maintenance work and repairs, unplug the machine from
the mains supply. Check that there is no voltage.
The electrical safety of this machine 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 house installation is checked by a qualified electrician.
The circuit diagram must be observed.
The machine may be operated only at the voltages and frequencies specified on the rating plate.
For machines delivered without a plug, a fixed connection must be installed as an overriding priority.
When the machine must be permanently connected (without a plug), a mains disconnector with all-pole
separation from the mains supply must be installed. The mains disconnector switch must have a contact
opening width of at least 3 mm, and must also be lockable in the neutral position.
The electrical connection must be secured as a separately fused circuit with slow fuses or circuit break-
ers. The fuse protection depends on the total connected load of the machine. The total connected load is
specified on the rating plate of the machine.
Additional recommendation: In the electric supply line, install a universal current-sensitive residual current
circuit breaker class B with a release current of 30 mA (DIN VDE 0664), as a frequency inverter is located
in the machine.
Machines delivered from the factory fitted with mains cable and safety plug (single-phase), or CEE plug
(EU only) (three phase) or no plug, may be connected only to the mains network indicated on the data
plate.
The following note applies to devices with a measuring conductor current > 16 A:
This device complies with IEC 61000-3-12, provided that the fault output S
sc
at the customer’s system connection point to the public mains supply is greater than or equal to 1.57 MVA
(R
sce
= 120).
It is the fitter’s or machine operator’s responsibility to ensure that this device is connected only to a fault out-
put of 1.57 MVA or more, upon consultation with the network operator if required.
Establishing equipotential bonding
Connect the machine to the on-site equipotential bonding system (Position of the connecting screw
16.1).
