DANGER
Before performing any electrical connections, ensure that both
DC and AC Switches are OFF. Otherwise, fatal injury can occur
due to the high voltage caused from AC and DC cables.

Connecting Protection Ground(PGND) Cables
【
Preparation
】
The ground cable and OT terminals have been prepared.
Ground cable : Outdoor copper-core cables with a cross sectional area of 4 mm
2
or
more are recommended.
OT terminal : OT1- 6 / 4.
NOTE
Good grounding for the inverter helps resist the impact of surge
voltage and improve the EMI performance. Connect the PGND
cable before connecting the AC power cables, DC power cables,
and communications cables.
【
Wiring Procedures
】
Step 1 : Remove an appropriate length of the insulation layer from the PGND cable
using a wire stripper; the length is a little bit longer than that of OT terminal’s crimping
end by 2mm~3mm, as shown in Figure 5.1.
