Control Voltage
Overvoltage
Overvoltage greater than 33 V has to be discharged by means of
the appropriate electrical equipment of the machine or installation.
This includes:
●
24V power supply units that reduce incoming overvoltage to
the allowed value.
●
Overvoltage limiters at the control cabinet input that limit ex‐
isting overvoltage to the allowed value. This, too, applies to
long 24V lines that have been run in parallel to power cables
and mains cables and can absorb overvoltage by inductive
or capacitive coupling.
Insulation monitoring impossible
The input 0 V is connected in conductive form to the housing po‐
tential. Insulation monitoring at +24 V and 0 V against housing is
impossible.
