Pay an attention to the phase
of power source when wiring.
(5) The recommended fuse sizes etc. are
shown in Table 6.1.
(6) In the case that a conduit tube for feild-
wiring not used,fix rubber bushes with
adhesive on the panel.
G Install an ELB in the power source.
If ELB is not used, it will cause electric shock or
fire at the worst.
G The tightening torque of each screw shall be as
follows.
M4:
1.0 to 1.3 N-m
M5:
2.0 to 2.5 N-m
M6:
4.0 to 5.0 N-m
M8:
9.0 to 11.0 N-m
M10: 18.0 to 23.0 N-m
Keep the above tightening torque when wiring work.
G Install main switch and ELB for each system
separately. Select the high response type ELB that
is acted within 0.1 second.
G Separate the control wiring between outdoor unit
and indoor unit more than approximately 5 to 6cm
from power supply wiring. Do not use a coaxial
cable.
