Methods of wiring power supply, units and connecting
remote controller wires
〉
Power supply wire
•
Remove the control box lid (2) and connect wires to the
power supply terminal block (3P) inside. In doing this, pull
the wires inside through rubber bush A and clamp the wires
along with other wires using clamp A, untightening the clip
of clamp A by pressing. After the connection, tighten clamp
A as before.
Transmission wire and remote controller wire
•
Remove the control box lid (1) and pull the wires inside
through rubber bush B and connect to the transmission
terminal block (6P).
After connection, attach sealing pad
•
(Be sure to attach it to prevent water from infi ltrating the unit
from the outside.)

CAUTION
Even if the control box lid (1)(2) is removed, pull the remote
•
controller wire, transmission wire and the power supply wire
inside the unit so that the wires do not come into contact
with the opening section of the metal casing.
Pass conduits through the wall and secure along with the
•
refrigerant pipe in order to prevent external pressure being
applied to transmission wire and power supply wire.
Arrange the wires and fi x a lid fi rmly so that the lid does not
•
fl oat during wiring work.
Do not clamp remote controller wire and transmission wire
•
together with power supply wire. Doing so may cause
malfunction.
Remote controller wire, transmission wire and power supply
•
wire should be located at least 5 in. from other electric
wires. Not following this guideline may result in malfunction
due to electrical noise.
WARNING
Never connect power supply wiring to the terminal block for
•
remote controller wiring as this could damage the entire
system.
Use only specifi ed wire and connect wires to the terminal
•
tightly. Be careful wires do not place external stress on
terminals. Keep wires in neat order so as to not obstruct
other equipment. Make sure that the electric box lid fi ts
tightly. Incomplete connections could result in overheating
and, in worse case, result in electric shock or fi re.
NOTE
Use round crimp-style terminals for connecting wires to the
1.
power supply terminal block.
If unavailable, observe the following points when wiring.
Do not connect wires of different gauge to the same
•
power supply terminal.
(Looseness in the connection may cause overheating.)
