Electric Wiring Work
Installation Manual BS Unit
187
Clamp power wiring and the grounding wire together with the
included clamp.
When clamping wiring, use the included clamping material 2) to
prevent outside pressure being exerted on the wiring
connections and clamp firmly.
When doing the wiring, make sure the wiring is neat and does
not cause the electric parts box lid to stick up, then close the
cover firmly. When attaching the electric parts box lid, make sure you do not pinch any wires. To
prevent the wires from damaging, be sure to pass all wires through the wiring guide.
After wiring work is complete, block all gaps in the holes for passing out wiring using sealing
material (locally procured).
(This is to prevent insects from entering the machine.)
PRECAUTIONS
1. Use ring-type crimp-style terminals for
connecting wires to the power supply terminal
board. 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.)
• When connecting wires of the same gauge,
connect them according to the righthand
figure.
• Use the specified electric wire. Connect the
wire securely to the terminal. Lock the wire down without applying excessive force to the
terminal.
• Use an appropriate screwdriver for tightening the terminal screws. A screwdriver with a small
head will strip the head and make proper tightening impossible.
• Over-tightening the terminal screws may break them.
• See the following table for the tightening torque of the terminal screws.
2. Do not connect wires of different gauge to the same grounding terminal. Looseness in the
connection may deteriorate protection.
3. Keep transmission wiring at least 2’’ away from power supply wiring. The equipment may
malfunction if subjected to electrical (external) noise.
4. For remote controller wiring, refer to the “INSTALLATION MANUAL OF REMOTE
CONTROLLER” attached to the remote controller.
5. Never connect power supply wiring to the terminal board for transmission wiring. A mistake of
the sort could damage the entire system.
6. Use only specified wire and tightly connect wires to terminals. 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 service cover. Make sure the cover closes tight.
Incomplete connections could result in overheating, and in worse case, electric shock or fire.
7. Use 2-core wires for branch wiring.
When wiring more than 2 indoor units and a remote controller with the same 3-core wire (or
other multi core wire), units sometimes stop unexpectedly because of trouble.
(3-core wires can be used only for the cool/heat selector)
8. Connect the cooling unit to pins F1 and F2 (outdoor unit) in the final BS unit.
