Wiring principle
General principles
(1) Wires, equipment and connectors supplied for use on the site must be in compliance with provisions of regulations
and engineering requirements.
(2) Only electricians holding qualification are allowed to perform wire connection on the site.
(3) Before connection work is started, the power supply must be shut off.
(4) Installer shall be responsible for any damage due to incorrect connection of the external circuit.
(5) Caution --- MUST use copper wires.
(6) Connection of power cable to the electric cabinet of the unit
(7) Power cables should be laid out through cabling trough, conduit tube or cable channel.
(8) Power cables to be connected into the electric cabinet must be protected with rubber or plastic to prevent scratch
by edge of metal plate.
(9) Power cables close to the electric cabinet of the unit must be fixed reliably to make the power terminal in the
cabinet free from an external force.
(10) Power cable must be grounded reliably.
