Connecting to Power Supply

The voltage and frequency of the
machine (see rating plate) must match
the voltage and frequency of the power
connection.
The minimum fuse protection of the
power connection must comply with the
specifications – see "Specifications".
The machine must be connected to the
power supply via an earth-leakage
circuit breaker to disconnect the power
supply if the differential current to earth
exceeds 30 mA.
The power connection must correspond
to IEC 60364 and relevant national
regulations.
The extension cord must have the
following minimum cross-section
depending on the mains voltage and
cord length.
Cord length Minimum cross-
section
400 V – 415 V / 3~:
up to 20 m 1.5 mm
20 m to 50 m 2.5 mm
230 V / 3~:
up to 20 m 2.5 mm
20 m to 50 m 4.0 mm
230 V – 240 V / 1~:
up to 20 m 2.5 mm
20 m to 50 m 4.0 mm
200 V / 3~:
up to 10 m 3.5 mm
10 m to 30 m 5.5 mm

Switching On

Turn on water supply
N
The machine may only be switched on
when the water intake hose is connected
and the water supply has been turned
on. Otherwise the machine may be
damaged due to lack of water.
When the device is on,
the "Operating status"
indicator is lit. The other
indicators light up briefly
and then remain dark.
NCompletely unroll the
high-pressure hose
When the machine is switched on,
voltage fluctuations that occur under
unfavorable mains conditions (high
power line impedance) may negatively
affect other connected electrical
appliances.
Trouble is not anticipated at power line
impedances less than 0.15 ohms.
