Installation
CAUTION
• When clamping wiring, use the included clamping material to prevent outside pressure being exerted on the wiring connections
and clamp firmly. Pass wiring through the wiring through holes to prevent damage to them.
• Make the lid on the electric parts box fits snugly by arranging the wires neatly and attaching the electric parts box lid firmly.
When attaching the electric parts box lid, make sure no wires get caught in the edges.
• To avoid short circuits in the electric parts box, be sure to apply the sealing material or putty (not included) to the wiring hole
to prevent the infiltration of water, insects or other small creatures.
• Outside the machine, separate the low voltage wiring (remote control wiring, outdoor unit wiring) and high voltage wiring
(power supply wiring, inter-unit wiring, ground wire, and other power wiring) at least 2 inches so that they do not pass through
the same place together. Proximity may cause electrical interference, malfunction, and breakage.
PRECAUTIONS:
Use round crimp-style terminals for connecting wires to the power supply terminal block. If unavailable, observe the following
points when wiring. Do not connect wires of different gauges to the same power supply terminal. Looseness in the connection
may cause overheating.
• Use the specified electric wire. Connect the wire securely to the terminal. Lock the wire down without applying excessive
force to the terminal. (Tightening torque: 0.97ft.lbf ±10%)
Tightening torque for the terminal screws.
• Use the correct screwdriver for tightening the terminal screws. If the blade of screwdriver is too small, the head of the
screw might be damaged, and the screw will not be properly tightened.
• If the terminal screws are tightened too hard, screws might be damaged. Refer to the table below for the tightening
torque of the terminal screws.
• Do not connect wires of different gauges to the same wiring terminal. Looseness in the connection can deteriorate pro-
tection.
• Outside of the unit, keep the low voltage wiring (transmission wiring) at least two inches away from the high voltage wir-
ing (power supply wiring, inter-unit wiring, ground wire, and other power wiring). The equipment may malfunction if sub-
jected to external electrical noise.
For remote controller wiring, refer to the INSTALLATION MANUAL OF REMOTE CONTROLLER attached to the remote
controller. Use only specified wire and connect wires to terminals tightly. Be careful wires do not place external stress on
terminals. Keep wiring in neat order and so as not to obstruct other equipment. such as popping open the electric parts
box lid. Make sure the lid closes tightly. Incomplete connections can result in overheating, and, in worse cases, electric
shock or fire.
