The work area must be secured against any third party entering the work area. Follow local
electrical engineering regulations while working on the machine. Never leave a machine
unattended. Use only tools that are insulated against electricity.
Only start work after you are familiar with the electrical engineering regulations that apply
to the local area.
Only use voltage seekers that comply with the regulations when troubleshooting. From
time to time check voltage seekers to ensure that they are operationally efficient.
2.6.1 Cables
Only use cables that are marked and rated according to the specifications in “1.1 Electri -
cal specifications”. Don’t use excessive length of the cables. If a very long cable is
needed we recommend that you use a cable rated for more current and connect it to
a distribution central near the machine. Never lay the cable in a loop when operating the ma -
chine, this will cause the cable to heat up and may cause fire. See “Figure 21” for explanation.
Figure 21 Recommended way to handle excessive cable length.

with the current EN-VDE directives (this applies to the protective earth conductor
