18.4 Electric wiring work
18.4.1 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 qualication are allowed to perform wire connection on the site.
(3) Before connection work is started, the power supply must be shut o󰀨.
(4) Installer shall be responsible for any damage due to incorrect connection of the external circuit.
(5) Only copper wires are allowed to be used.
(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 xed reliably to make the power terminal in
the cabinet free from an external force.
(10) Power cable must be grounded reliably.
