Connection to the converter
CAUTION
The standar
d insulating system is suitable for converter voltages up to
460 V. For higher voltages, a special insulating system must be used or
special measures must be taken, e.g. an output filter.
CAUTION
Machines must always be connected to frequency
shielded machine supply cables. The most effecti
converters using
ve method of

e (with a metal screw connections) over a large surface
shielding is to conductively connect the cable to the metal terminal bo
of the machin
area.
Note
EMC
Please observe the section containing instructions on ensuring electromagnetic
compatibility.
