2. Safety instructions for electric drives and controllers
Festo P.BE-CMMP-FHPP-DN-SW-EN en 0708NH 17
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.
Warning
The device has an intermediate fast discharge circuit in accordance
with EN 60204 section 6.2.4. In certain device constellations,
particularly where several motor controllers are switched parallel in
the intermediate circuit or with a non-connected braking resistance,
the fast discharge may not have any effect. The motor controllers
can stand under dangerous tension for up to 5 minutes after being
switched off (capacitor residual charge).
2.4.4 Protection by low voltage (PELV) against electric shock
Voltages from 5 to 50 V on the connections and terminals of the motor controller are
protective small voltages which can be touched without danger in accordance with the
following standards:
- International: IEC 60364-4-41
- European countries in the EU: EN 50178/1998, section 5.2.8.1
