When connecting grounding wire, please ensure all grounding wires and grounding devices are
connected with earth reliably, which is to avoid electrification on the outer cover of the device.
The grounding of the PCS cannot be the same as the lightning rod of installed building, the two must
be separated (as shown in Figure3-15). The grounding of the PCS must be connected to the
grounding system directly, and the impedance should be less than 20m
Ω

Connect the wires of AC output side.
Lead the AC output wires go through the bottom wiring hole (as shown in Figure3-13), and connect
them to the corresponding output terminal bars (as shown in Figure3-16).
For the grid voltage is high and dangerous, while wiring, please ensure that the AC distribution
breaker is disconnected to guarantee the wiring terminal without electricity. We suggest using bolt
M16 to fasten AC wires, corresponding torque is 750~1000 Kgf.cm.
