control boar d individually.
B
Secure the cable ont o the control boar d with
the cord clamp .
C
Refix the contr ol cover t o the original
position with the scr ew.
D
Use a recogniz ed circuit br eaker 20A ( 12K,18K),
25A (24K) bet ween the pow er source
and the unit. A disconnecting device t o
adequately disconnect all supply lines must
be fitt ed.
After the confirmation of the above conditions, prepare the wiring as follows:
Never fail to have an individual power circuit specifically for the air conditioner. A s for
the method of wiring, be guided by the cir cuit diagr am post ed on the inside of contr ol
cover .
The scr ew which fast en the wiring in the casing of electrical fittings ar e liable to come
loose from vibr ations to which the unit is subject ed during the course of
transportation. Check them and make sur e that they ar e all tightly fast ened. (If they
are loose, it may cause burn-out of the wires. )
Specification of power source.
Confirm that electrical capabilit y is sufficient.
The starting v oltage is maintained at more than 90 percent of the rat ed voltage marked
on the name plat e.
Confirm that the cable thickness is as specified in the power source specification.
(Particularly not e the relation betw een cable length and thickness. (R efer to page 15))
Always install an earth leakage circuit breaker in a w et or moist ar ea.
The following w ould be caused by v oltage dr op.
The means f or disconnection fr om a power supply shall be incorpor ated in the fix ed
wiring and have an air gap contact separation of at least 3mm in each active(phase )
conductors.
Vibration of a magnetic swit ch, which will damage the contact point, f use breaking, disturbance of the
normal function of the ov erload.
