3.2.4 Grounding Connections
DANGER!
 The inverter shall be connected to a Protective Ground (PE).
 Use the minimum ground wiring gauge as indicated in the Table B.1 on page
212, Table B.2 on page 213 and Table B.3 on page 214.
 Connect the inverter grounding connections to a ground bus bar, to a single
ground point, or to a common grounding point (impedance ≤ 10 Ω).
 The neutral conductor of the network shall be solidly grounded; however,
this conductor shall not be used to ground the inverter.
 It is necessary to use a copper cable with 10 mm
2
minimum or 2 cables with
the same wire gauge as specified in Table B.1 on page 212, Table B.2 on
page 213 and Table B.3 on page 214 for connecting the inverter to the
ground protection to be in accordance with IEC61800-5-1 since the leakage
current is greater than 3.5 mA AC.
3.2.5 Control Connections
The control connections (analog inputs/outputs and digital inputs/outputs), shall be performed
in connector XC1 of the CC700 Control Board. Functions and typical connections are presented
in Figure 3.5 on page 21.
