NOTE
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.
Step 1
Remove an appropriate length of the insulation layer from the PGND cable using a wire
Stripper; the length should be 2mm~3mm longer than OT terminal’s crimping end, as shown in
Figure 5.1.
Figure 5.1 Stripped length (unit: mm)
Step 2
Insert the exposed core wires into the crimping areas of the OT terminal and crimp them
using hydraulic pliers, as shown in Figure 5.2.

Step 3
Remove the ground screws from the ground points, secure the PGND cable (done by
step 1 & 2) using the ground bolts, and tighten the bolts to a torque of 5 N•m using a socket
wrench, as shown in Figure 5.3. PE wire must be well grounded to ensure that impedance
between Neutral wire and Earth wire be less than 10Ω.
