CAUTION!
Damage through electrical destruction.
The component assembly can be destroyed by electricity if it is removed
when the power is turned on.
Therefore:
– Make sure that the power to all electrical connections is shut off and
secured to prevent from being turned back on.
– Using suitable measuring equipment, check to make sure that none
of the connections are carrying live current before beginning work on
the electrical connections.
– Only disassemble the connections and remove the connection once
you are completely certain that the component assembly is not under
power.
WARNING!
Danger of injury due to uncontrollable behavior of the machine/line.
The behavior of the machine/line can change as a result of removing the
component assembly with the power source connected.
Therefore:
– Make sure that the power to all electrical connections is shut off and
secured to prevent from being turned back on.
– Using suitable measuring equipment check, to make sure, that none
of the connections are carrying live current before beginning work on
the electrical connections.
– Only disassemble the connections and remove the connection once
you are completely certain that the component assembly is not under
power.
– Hanging loads could disconnect unexpectedly and fall, because STO
is enabled during the removing of the assembly group.
The qualified professional in electrical drive technology and motion applications who is
