• Screws on terminal block must not be unscrewed with
the torque less than 0.89 lbf.ft.
• Since it has the external power supply, refer to the
outdoor unit installation manual for MAIN POWER.
• When installing the indoor unit in a computer room,
use the double shielded (tape aluminum / polyester
braid + copper) cable of FROHH2R type.

2 As shown in the figure, peel off the shields from the
rubber and wire of the power cable.
• Peel off 0.79 inch (20 mm) of cable shields from the
pre-installed tube.
CAUTION
• For information about the power cable specifications
for indoor and outdoor units, refer to the installation
manual.
• After peeling off cable wires from the pre-installed
tube, insert a contraction tube.
• If cable wires are connected without using connecting
sleeves, their contact area becomes reduced, or
corrosion develops on the outer surfaces of the wires
(copper wires) over a long time. This may cause an
increase of resistance (reduction of passing current)
and consequently may result in a fire.
