IGBT Power Converter 200A [Patent No. EP1 126 591 B1] 02.08 25
4 Electrical connection
4.1.1 Suitable cables and cross-sections
PE conductor The cross-section of the PE conductor must be at least as large as the cross-
section of the voltage supply conductors to the power section. If the
protective earth (PE) conductor is not part of the supply cable or its sheathing,
the chosen conductor must have a cross-section of at least 2.5 mm
2
(if
mechanically protected) or at least 4mm
2
(if the PE conductor is not
mechanically protected).
v see VDE 0100 Part 540
Control section The screw terminals for the voltage supply to the control section are laid out
for a conductor cross-section between 0.5 mm
2
and 2.5 mm
2
. The minimum
conductor cross-section must not be less than 0.5
2
mm. Fusing of the cable
must correspond to the selected conductor cross-section.
Power consumption is approx. 75 VA.

The minimum conductor cross-section chosen must be adequate
for the maximum conductor current. The electrical connection is
made via screw terminals on the converter. We recommend the use
of a shielded cable to reduce EMC interference emission.

the suitable cables
A
The cable cross-section in the load and choke circuits must not be
less than the cross-section of the supply leads to the power
section!
