If the installation place is near the ground, connect the PGND cable to the ground before installing the
inverter on the wall.
Figure 18 - Connecting the ground terminal
Prerequisites:
Prepare the PGND cables to be connected (outdoor power cables with a cross-section of 8 mm
2
are
recommended for grounding purposes); it is recommended to use yellow-green cables for better
identification.
Procedure:
1)
Remove an adequate length of the external insulation layer using a wire stripper, as shown in Figure
below.
Note:
L2 is approximately 2-3 mm longer than L1
Figure 19 – Preparing the ground cable (1)
2)
Insert the exposed wires in the OT terminal and crimp them using a crimping tool, as shown in
Figure below.
Note 1
: L3 is the length between the insulation layer of the ground cable and the crimped part. L4 is the
distance between the crimped part and the conductor wires protruding from the crimped part.
