5.3 Connecting the PE Cable

● 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.
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.
