Grounding
5.1.1 Preparation
The ground cable and OT terminals have been prepared.
a. Ground cable: Outdoor copper-core cables with a cross sectional area of 4mm² or more are recommended.
b. OT terminal: OT6~4.
NOTE
NOTE
Before performing any electrical connections, ensure that both DC and AC
Switches are OFF. Otherwise, fatal injury can occur due to the high voltage .
OT 6~4
Good grounding for the inverter helps resist the impact of surge voltage and
improve the EMI performance. Connect the PGND cable before first connecting
the AC power cables, DC power cables, and communication cables.
It is recommended that the ground cable be connected to a nearby ground
position. For a system with multiple inverters connected in parallel, connect the
ground points of all inverters to ensure equipotential connections.
