Electric Wiring Work - Daikin FCW15ARV16 Installation Manual

8. ELECTRIC WIRING WORK

• Electric wiring work must be conducted by electrician authorized by power companies. (Only licensed
electrician can conduct electric work and earth connections.)
• All wiring must be performed by an authorized electrician.
• A circuit breaker capable of shutting down power supply to the entire system must be installed.
(T his installation of an earth leakage circuit breaker is mandatory for the prevention of electric shocks and
fire disasters. )
• Make sure that power supply is 230V
• Do not turn on the power supply (of the indoor unit) until all the installation work is completed.
• Be sure to ground the air conditioner.
• Refer to the installation manual attached to the chiller unit for the size of power supply electric wire
connected to the chiller unit, the capacity of the circuit breaker and switch, and wiring instructions.
• Do not connect the earth wire to gas pipes, plumbing pipes, lightning rods, or telephone earth wires.
• Gas pipes: might cause explosions or fire if gas leaks.
• Plumbing pipes: no earth effect if hard vinyl piping is used.
• Telephone earth wires or lightning rods: might cause abnormally high electric potential in the earth
during lighting storms.
• For electric wiring work, refer to also "WIRING DIAGRAM" attached to the control box lid.
• Never connect the power supply wire to the terminal block for remote controller wire, or otherwise the entire
system may be damaged.
• Do not touch the printed circuit board ASSY during the wiring work. Otherwise, it may cause damage.
NOTE-,g.
1. Shows only in case of protected pipes. Use H07RN-F in case of no protection.
2. Supply cords shall not be lighter than polychloroprene sheathed flexible cord
(code designation 60245 IEC 57)
3. Vinyl cord with sheath or cable (Insulated thickness: 1 mm or more)
Connection of wiring between units, earth wire
• Wiring the units and earth wire
Remove the control box lid and connect wires of matching number
to the terminal block for wiring the units (4 P) inside and connect
the earth wire to the earth terminal. In doing this, pull the wires
inside through the hole and fix the wires securely with the included
clamp (4)
-�CAUTION-----------------------
• Never connect the power supply wiring to the terminal block for wiring the units.
If may damage the total system.

of the transmission earth and the remot e contro lle r in order
to prevent the intrusion of water and small animals into the air

conditioner after the system is wired.
• Cut the sealing pad - small into two pieces and wrap each
wiring with each piece.
• Seal the clearance around the wirings with putty or thermal
insulation material (field supply). (If insects and small animals
get into the indoor unit, short circuiting may occur inside the
control box.)
• After all the wiring connections are done, fill in any gaps in the
through holes with putty or insulation (procured locally) to prevent
small animals and insects from entering the unit from outside. (If
any do get in, they could cause short circuits in the control box.)
• Outside the machine, separate the weak wiring and strong wiring
(interunit, earth, and other power wiring) at least 50 mm
so that they do not pass through the same place together.

Proximity may cause electricafinterference, malfunctions,
