CAUTION
Check that the power supply voltage is within the speci
fi
ed
▪
range. If a power supply voltage outside the speci
fi
cation is
input, it will cause trouble.
Recheck the wiring. Incorrect wiring will cause trouble.
▪
After installation work is completed, check the following contents:
Is Central remote controller power supply cable and transmission
cable wiring work complete?
Does the power supply match the rating of the Central remote
controller?
Turn on the power of Central remote controller. Since there is no
power switch at this controller main unit, turn on the power by
means of the power distribution panel (breaker).
If the following installer setting screen is displayed at the screen
of the Central remote controller panel, installation work is com-
plete.
For setting and operating of the Central remote controller, refer to the
separate operating manual.
Since there is some kind of a problem when the installer setting
*
screen does not appear, recheck the work contents.
