Danger
Danger to life. Live components.

The machine and the relevant additional devices must be connected by an electrical company authorised by the
relevant electricity supplier as per the locally applicable standards and regulations.

When performing installation and maintenance work, unplug the machine from the power network. 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 very important that this
basic safety requirement is tested and in case of doubt the
house installation is checked by a qualified electrician.

The circuit diagram must be observed.

The equipment may only be operated at the voltages and
frequencies specified on the rating plate.

A fixed connection must as a priority be installed for ma-
chines that are delivered without a power cord.

When the machine must be permanently connected (with-
out a plug), a mains disconnector with all-pole separation
from the network 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 breakers. The protec-
tion depends on the total power consumption of the ma-
chine. The total connected load is specified on the rating
plate of the machine

In the electric supply line, install a universal current sensi-
tive residual current circuit breaker class B with a tripping
current of 30 mA (DIN VDE 0664) as a frequency inverter is
located in the machine.

Machines delivered from the factory equipped with mains
cable and safety plug (single phase), or CEE plug are (triple
phase), may only be connected to the mains network indi-
cated on the nameplate.
17.1 Connecting the mains cable
Requirements for the mains cable

Cable type: Type H07 RN-F or equivalent

The wires must be fitted with wire end ferrules.

Cross section and number of cores: suitable for on-site power and protection
for more information see the sticker in the front panel
Connect the mains
cable to the rear of the
machine. Withdraw the mains
cable at the front and
route it to the left. Follow the wiring dia-
gram (

‎
17.3).
Connect the wires of the
mains cable according
to the connection dia-
gram. Close the quick release
connectors.
If necessary plug bridges.
Firmly press the bridges
with a screwdriver. Connect the green-yellow
wire to the distributor of
the earth wires. Attach the mains cable to
the mounting plate with a
cable tie for strain relief.
17.2 Establishing an earth connection

Connect the machine into the equipotential bonding system.
INFO The terminal screw is located behind the right rear leg of the machine. It is identified with the symbol.
