Damaged laboratory safety cables must be immediately barred from further use
and removed from the test area.
1.3
Note to electrical access of facility
According to EN 60204-1 (VDE 0113-1) part 8.2.8, a supply cable with an additional protective conductor is
required for the supply of the CP factory installations. Since a leakage current of >10mA can flow depending
on the configuration, an additional protective conductor with 10mm² is necessary.
Please see also DIN EN 60204-1.
