10. Operating the machine
10.1 Electrical connection
Danger of electric shock!
Observe the safety instructions in
the section "For your safety" (
If using a cable drum, the
connection cord must be unwound
completely, otherwise electrical
resistance may cause loss of power
and overheating.
Only cables which are no lighter than the
following rubber sheathed cables may be
used as electric cables:
H07 RN-F DIN/VDE 0282
Minimum cross-section:
up to 25 m length: 1,5 mm²
up to 50 m length: 2,5 mm²
The connectors of the electric cables must
be made of rubber or have a rubber cover
and conform to the following standard:
DIN/VDE 0620
The mains voltage and mains frequency
must correspond to the information on the
identification plate and the information
contained in the section "Technical
specifications" (
17.).
The power cable must be adequately
protected by fuse (
17.).
This machine is intended for operation with
a power supply having a system
impedance of Z
at the transfer point
max
(house connection) of maximum
0,49 ohms (at 50 Hz).
The user must ensure that the machine is
only operated with a power supply which
meets this requirement. If necessary, this
information can be obtained from the local
electric power company.
10.2 Strain relief
During working, the strain relief
4.).
prevents any unintentional
disconnection of the electric cable and any
