Context
Good grounding for the SUN2000 helps resist the impact of surge voltage and improve EMI
performance. Connect the PGND cable before connecting the AC power cables, DC power
cables, and communications 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.
If the installation location is near the ground, connect the PGND cable to the ground before installing the
SUN2000.
A ground terminal has five parts, as shown in Figure 5-1.

(1) M6 welded stud
(2) OT terminal
(3) Flat washer
(4) Spring washer
(5) Nut
Procedure
Step 1 Remove an appropriate length of the insulation layer from the PGND cable using a wire
stripper, as shown in Figure 5-2.
A 6 mm
2
or 10 AWG outdoor power cable is recommended for grounding purposes.
Figure 5-2 Stripped length
Note: L2 is 2 mm to 3 mm longer than L1.
Step 2 Insert the exposed core wires into the conductor crimp area of the OT terminal and crimp
them using a crimping tool, as shown in Figure 5-3.
