WARNING
Terminals must be used for connection. Use
round-type
terminals
specifications to connect the power cables.
Do not directly connect the cable ends. Use
the correct terminal, or it may cause heating
and fire.
3. Fasten and fix the cables with wire clamp to avoid
stress on the terminals.
4. Press the plastic board of the power line terminal back
and confirm that the power phase sequence is correct
again.
WARNING
Select a proper torque according to the screw
size.
Too small torque may cause poor contact,
resulting in heating of the terminals and fire.
Too large torque may damage the screws
and power supply terminals.

CAUTION
During installation, the earth wire shall be
longer than the current carrying conductor to
ensure that when the fixing device is loose,
the earth wire is still not stressed and can be
reliably earthed.
When inserting the strong-current cables and
communication wiring into the wiring holes,
they must be equipped with wiring across
rings. Otherwise, they may be worn out by
the sheet mental and cause electric leakage
or short circuit.
WARNING
Do not connect the earth wire of the lightning
rod to the unit shell. The earth wires of the
lightning rod and the power cable must be
configured separately.
Each unit shall be equipped with a circuit
breaker for short circuits and abnormal
overload protection. In addition, the indoor
and ODUs shall be equipped with a main
circuit breaker respectively to connect or
disconnect the main power supply of the
indoor and ODUs.
