● 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 silicone sealant or paint be applied around the ground terminal
after the PE cable is connected.
Procedure
Step 1 Crimp OT terminals.
● 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 wires completely. The core wires must contact the OT
terminal closely.
● Wrap the wire crimping area with heat shrink tubing or PVC insulation tape.
The heat shrink tubing is used as an example.
● When using a heat gun, protect devices from being scorched.
