10.3 COMMON WIRING
!
C A U T I O N
All the field wiring and electrical components must comply with local
codes.
10.3.1 Electrical wiring between indoor unit
and outdoor unit
• Connect the electrical wires between the indoor unit and the
outdoor unit, as shown below.
• follow local codes and regulations when performing
electrical wiring.
• Use twist pair wire (more than 0.75 mm²) for operation wiring
between outdoor unit and indoor unit.
• Use 2-core wire for the operating line (Do not use wire with
more than 3 cores).
• Use shielded wires for intermediate wiring to protect the
units from noise obstacle at length of less than 300 m and
size complied with local code.
• open a hole near the connection hole of power source
wiring when multiple outdoor units are connected from one
power source line.
• The recommended breaker sizes are detailed in the Wire
size section.
•
In the case that a conduit tube for field-wiring is not used, fix
rubber bushes with adhesive on the panel.
•
All the field wiring and equipment must comply with local and
international codes.
• H-lInK twist pair shielded cable must be grounded in the
outdoor unit side.
!
C A U T I O N
• Pay attention to the connection of the operating line. Incorrect
connection may cause the failure of PCB.
•
Check to ensure that the field supplied electrical components
(mains power switches, circuit breakers, wires, connectors and wire
terminals) have been properly selected according to the electrical
data indicated on this chapter and they comply with national and local
codes. If it is necessary, contact with your local authority in regards to
standards, rules, regulations, etc.
