2. Safety instructions for electric drives and controllers
Festo P.BE-CMMD-AS-HW-EN 1002NH 19
Warning
Before switching the device on, attach the intended covers and
protective screens so that the device cannot be touched.
For built-in devices, make sure that there is an external housing,
such as a control cabinet, to ensure that the electric components
cannot be touched.
The standards EN 60204-1 and EN 50178 must be observed.
Warning
Ensure that the minimum copper cross section is used for the entire
length of the protective earth conductor in accordance with
standard EN 60204.
Warning
Before commissioning, also for brief measuring and test
purposes, always connect the protective conductor to all
electric devices or connect to an earth cable in accordance with
the connection diagram.
Otherwise, high voltages may occur on the housing. These could
cause an electric shock.
Warning
Do not touch the electrical connection points of the components
when the device is switched on.
Warning
Before touching electric components with voltages over 50 V,
disconnect the device from the mains or voltage source.
Protect the device against being switched on again.
Warning
During installation note the amount of intermediate circuit
voltage, especially with regard to insulation and protective
measures.
Make sure that the earthing, the cross section size of the conductor
and the corresponding short-circuit protection are correct.
