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.
Procedure
Step 1 Remove an appropriate length of the insulation layer from the PGND cable using a wire
stripper, as shown in Figure 5-1.
Figure 5-1 Stripped length (unit: mm)
Step 2 Insert the exposed core wires into the crimping area of the OT terminal and crimp them using
hydraulic pliers, as shown in Figure 5-2.
Figure 5-2 Crimping a cable (unit: mm)
The crimping must result in full containment of the cable conductors and complete contact between the
cable conductors and the terminal.
Step 3 Remove the ground screws from the ground points.
Step 4 Secure the PGND cable using the ground screw and tighten the screw to a torque of 5 N·m
using a socket wrench.
