Defective Electric Connection Lines
Often, insulation damages occur on electrical connection
lines.
The possible causes are:
• Drag marks if connection lines are led through window or
door clearances.
• Kinks due to improper attachment or routing of the
connection line.
• Cuts caused by running over the connection line.
• Insulation damages caused by pulling the connection
line out of the wall socket.
• Fissures caused by the aging of the insulation. Such
defective electrical connection lines must not be
used and are, due to the insulation damages, life
threatening!
Regularly check the electrical connection lines for
damages. Please make sure that the connection lines are
disconnected from the mains supply during the check.
Electrical connection lines must meet the applicable VDE
and DIN regulations and the provisions of the local power
supply company. Only use connection lines labeled with
H07RN. The labeling of the connection cable with the type
specification is required.
• Extension lines up to a length of 25 m must have a cross
section of 1.5 mm2, lines with a length exceeding 25 m
must have a minimum cross section of 2.5 mm2.
• The mains connection is protected with a 16 A delay-
action fuse.
Threephase Current Motor
• The supply voltage must be 380-420 V/50 Hz.
• The connection to the mains supply and the extension
lines must be of a five-conductor type (3 P + N + SL).
• The extension lines must have a minimum cross section
of 1.5 mm.
• The mains connection is protected with a maximum of
16 A.
• In case of a connection to the mains supply or if the
machine is moved to a different location, the direction of
rotation must be checked. If required, the polarity must
be reversed (see also Fig. 03).
Connections and repairs of the electrical equipment may
only be performed by an electrician.
If you have further questions, please specify the
following:
• Motor manufacturer and type
• Kind of current of the motor
• Data from the machine type plate
