ELECTRICAL WIRING
5.4 ELECTRICAL CONNECTION OF THE INDOOR UNIT
!
C A U T I O N
Check to ensure that the field supplied electrical components (mains pow-
er 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, regula-
tions, etc.
5.4.1 Wiring size
Use wires which are not lighter than the polychloroprene
sheathed flexible cord (code designation 60245 IEC 57).

5.5 TRANSMISSION WIRING BETWEEN OUTDOOR AND INDOOR UNIT
• The transmission is wired to terminals 1-2.
• The H-LINK II wiring system requires only two transmission
cables that connect the indoor unit and the outdoor unit.

devices
!
C A U T I O N
• Ensure specifically that there is an Earth Leakage Breaker (ELB) in-
stalled for the units.
• If the installation is already equipped with an Earth Leakage Breaker
(ELB), ensure that its rated current is large enough to hold the current
of the units.
?
N O T E
• Electric fuses can be used instead of magnetic Circuit Breakers (CB).
In that case, select fuses with similar rated values as the CB.
• The Earth Leakage Breaker (ELB) mentioned on this manual is also
commonly known as Residual Current Device (RCD) or Residual Cur-
rent Circuit Breaker (RCCB).
• The Circuit Breakers (CB) are also known as Thermal-Magnetic Cir-
2
cuit Breakers or just Magnetic Circuit Breakers (MCB).

• Use twisted shielded pair cable or shielded pair cable for
transmission wires between the indoor and the outdoor units,
and connect the shielded part (only one side) to the earth
screw in the electrical box of the indoor unit.
• In the event that a conduit tube for field-wiring is not used, fix
rubber bushes to the panel with adhesive.

C A U T I O N
Ensure that the transmission wiring is not wrongly connected to any live
part that could be damaged the PCB.

Make sure that this configuration is set after installing / wiring the indoor
unit. If not, set this Optional Function as indicated above.
