INSTALLATION AND CONNECTION
3.2.5 Grounding Connections
!
DANGER!
The inverter must be obligatorily connected to a protective ground (PE).
Use grounding wiring with a gauge at least equal to that indicated in
Connect the grounding points of the inverter to a specific grounding rod, or specific grounding point,
or to the general grounding point (resistance
≤
10
Ω
).
To comply with IEC 61800-5-1 standard, connect the inverter to the ground by using a single
conductor copper cable with a minimum wire gauge of 10 mm
2
or a two-conductor cable with the
same wire gauge of the grounding cable specified in
since the leakage current is greater
than 3.5 mA AC.
!
DANGER!
Do not share the grounding wiring with other equipment that operate with high currents (ex.: high
power motors, soldering machines, etc.). When installing several inverters, follow the procedures
presented in
for the grounding connection.
!
WARNING!
The neutral conductor of the network that powers the inverter cannot be used to ground the inverter.
