All electrical work must be carried out by a qualified electrician
in accordance with local and national safety regulations.
- The electrical installation must be in compliance with current local
and national safety regulations (DIN VDE 0100 in Germany).
- The connection to the power supply must comply with national reg-
ulations. The power outlet must be accessible after the machine
has been installed. An electrical safety test must be carried out af-
ter installation and after any servicing work.
- If the machine is hard-wired to the power supply, a power switch
capable of disconnecting the machine at all poles must be in-
stalled. This power switch must be designed to operate at the rated
current, have a contact gap of at least 1" (3 mm), and also be lock-
able in the off position.
- If necessary, equipotential bonding must be carried out.
- The rated loads are specified on the data plate and in the circuit di-
agram supplied with the machine.
- The rotational direction of motorized power units depends on the
electrical connection of the machine. Machine phases must be con-
nected in the correct sequence (clockwise rotating field).
- For added safety, the cleaning machine should be protected by a
type B residual current device with a trip current of 30 mA
(DIN VDE 0664).
You can find more information on electrical connection in the instal-
lation diagram supplied with the machine.
The machine must only be operated with the voltage, frequency, and
fuse rating shown on the data plate.
The data plate showing relevant certification marks is located behind
the service cover on the infeed side of the machine.
The wiring diagram is supplied with the machine.
