Connecting a PE Cable
4.2
•
The PE point at the AC output port is used
only as a PE equipotential point, not a
substitute for the PE point on the
enclosure.
•
It is recommended that silica gel or paint
be applied around the ground terminal
after the PE cable is connected.
Do not connect the neutral wire to the
enclosure as a PE cable. Otherwise, electric
shocks may occur.

Installing the AC Output Power Cable
4.3
•
Use a socket wrench and extension rod to connect the AC power cable. The extension rod
must be longer than 100 mm.
•
Sufficient slack should be provided in the PE cable to ensure that the last cable bearing the
force is the PE cable when the AC output power cable bears pulling force due to force
majeure.
•
Do not install third-party devices in the AC connection box.
•
You need to prepare M8 OT terminals by yourself.
