Installation and Connection
3.2.4.1 Input Connections
DANGER!
Provide a disconnection device for the input power supply of the converter.
This device shall disconnect the input power supply for the converter when needed (for instance,
during servicing).
ATTENTION!
The power supply that feeds the converter shall have a grounded neutral.
NOTE!
The input power supply voltage shall be compatible with the converter rated voltage.
NOTE!
Power factor correction capacitors are not needed at the converter input (U, V, W).

3.2.5 Grounding Connections
DANGER!
Do not share the grounding wiring with other equipment that operate with high currents (e.g. high power
motors, soldering machines, etc.). When installing several converters, follow the procedures presented
in
Figure 3.21 on page 3-27
ATTENTION!
The neutral conductor of the network must be solidly grounded; however, this conductor must not be
used to ground the converter.
DANGER!
The converter must be obligatorily connected to a protective ground (PE).
Observe the following:
- Use a minimum wire gauge for ground connection equal to the indicated in
a
Table 3.6 on page
gauge is required.
- Connect the converter grounding connections to a ground bus bar, to a single ground point, or to a
common grounding point (impedance ≤ 10 Ω).
- To comply with IEC 61800-5-1 standard, connect the converter to the ground by using a single
conductor copper cable with a minimum wire gauge of 10 mm2, since the leakage current is greater
than 3.5 mA CA.

for the grounding connection.
