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.
10.3.2 Wire size and main switch protection
