5.3 Connecting the PE Cable
D ANGER
● Ensure that the PE cable is securely connected. Otherwise, electric shocks may
occur.
● Do not connect the neutral wire to the enclosure as a PE cable. Otherwise,
electric shocks may occur.
NO TE
● The PE point at the AC output port is used only as a PE equipotential bonding point,
and cannot substitute for the PE point on the enclosure.
● It is recommended that silicone grease or paint be applied around the ground terminal
after the PE cable is connected.
● You can enable or disable phase-to-ground short-circuit protection on the app (choose
Settings > Feature parameters > Phase-to-ground short-circuit protection) to
address the situation in which a phase wire is short-circuited to PE. If this function is
disabled, the inverter detects the alarm and can connect to the power grid and generate
power normally.
Procedure
Step 1 Crimp an OT terminal.
NO TICE
● Avoid scratching the core wire when stripping a cable.
● The cavity formed after the conductor crimp strip of the OT terminal is crimped
must wrap the core wire completely. The core wire must make close contact
with the OT terminal.
● Wrap the wire crimping area with heat shrink tubing or insulation tape. The
heat shrink tubing is used as an example.
● Use a heat gun carefully to avoid heat damage to the equipment.
