Installing the unit
Check that the product mounting bracket and
drop-prevention wire have been attached to the bottom
surface of the unit.
Exercise great care during the installation work to ensure
safety by providing a stepladder or other means which is
strong enough for the unit’s weight and high enough for
the installation location, and ensure that the unit will not
be dropped.
During the installation work, be sure to hold the unit by
its base area. Installing the unit while holding it by its lens
area or rotating parts may cause the unit to malfunction
after installation.
Ensure that the installation work is undertaken by a
two-member crew.
1
Attach the drop-prevention wire.
While holding the unit, attach the hook of the
drop-prevention wire to the installation surface bracket.
Try pulling the wire, and check that the metal hook at
the end of the wire is definitely looped through the hole
in the installation surface bracket.
The wire is designed to support only the product which
is suspended: Do not subject it to any other loads as
well.

Align the
(part A) of the installation
surface bracket with the hole (part B)
in the product mounting bracket, and
also align the protrusion (part C) of
the installation surface bracket with
the protrusion (part D) in the product
mounting bracket.
3
Turn the unit in the direction shown by
the arrow.
Check that the installation surface bracket and product
mounting bracket engage properly.
Keep turning the unit until it will go no further.
If the unit is not turned all the way, the brackets will not
be engaged completely, and the unit may fall down.
