Outdoor unit
- Connect the wires to the terminals on the
control board individually.
- Secure the cable onto the control board with
the cord clamp.
- Use a recognized circuit breaker between
the power source and the unit.
A disconnecting device to adequately discon-
nect all supply lines must be fitted.

! CAUTION
According to the confirmation of the above con-
ditions, prepare the wiring as follows.
1
Never fail to have an individual power circuit
specifically for the air conditioner. As for the
method of wiring, be guided by the circuit
diagram posted on the inside of control
cover.
2
The screw which fasten the wiring in the
casing of electrical fittings are liable to be-
come loose from vibrations to which the unit
is subjected during the transportation.
Check them and make sure that They all
are tightly fastened. (If they are loose, it
could cause burn-out of the wires.)
3
Specification of power source.
4
Confirm that electrical capacity is sufficient.
5
See that the starting voltage is maintained
at more than 90 percent of the rated voltage
marked on the name plate.
6
Confirm that the cable thickness is as speci-
fied in the power source specification.
(Particularly note the relation between cable
length and thickness.
7
Always install an earth leakage circuit
breaker in a wet or moist area.
8
The following would be caused by voltage
drop.
- Vibration of a magnetic switch, which will
damage the contact point, fuse breaking,
disturbance of the normal function of the
overload.
9
The means for disconnection from a power
supply shall be incorporated in the fixed
wiring and have an air gap contact separa-
tion of at least 3mm in each active(phase)
conductors.
