Festo P.BE-CMMP-CO-SW-EN 0708NH
Warning
In accordance with standard EN 60617, pay attention to the
minimum copper diameter for the protective conductor connection
in its entire length!
Warning
Prior to start-up, also for short-time measurement and testing
purposes, always connect the protective conductor to all electrical
devices in accordance with the connection plan or with the earthing
conductor.
Otherwise, high voltages may occur on the housing, which can
cause electric shock.
Warning
Do not touch the components' electrical connection points in the
switched-on state.
Warning
Before access to electrical parts with voltages greater than
50 volts, separate the device from the mains network or the
voltage source.
Secure to prevent switching back on.
Warning
During installation, pay attention to the level of intermediate circuit
voltage especially with regard to insulation and protective
measures.
Ensure proper earthing, conductor dimensioning and appropriate
protection against short circuiting.
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 remain under dangerous voltage for up to 5 minutes after they
are switched off (residual condensor charge).
