Installation precautions
Be absolutely sure to use the bracket and screws
supplied when installing the unit.
Do not mount the unit by employing any methods other
than those specified.
Do not remodel the mounting bracket or mounting screws
provided with the unit.
Tightening up the mounting screws
Tighten up the screws and bolts securely to the degree
that is appropriate for each of the materials used in the
mounting location and structures.
After tightening up the screws and bolts, check that
there is no unsteadiness and that the parts have been
tightened securely.
Use the specified tools and tighten the screws firmly.
When the unit is no longer going to be used, do not
leave it lying around, but be absolutely sure to dispose
of it properly.
For details on how to remove the unit, refer to “Removing
the camera” (page 26).
When installing, transferring or disposing of the unit, be
absolutely sure to hold it by its pedestal area.
Problems may result if the camera head is held or rotated.
Do not attach a filter, hood, extender or other parts to
the unit.
Use the dedicated AC adapter and power cable provided
with the unit.
Connect the AC adapter and power cable to the power inlet
securely.
Installing the AC adapter
Do not place the adapter directly onto a ceiling panel or
other such surface.
Extreme danger is posed when water has collected on
the surface as a result of leaking rain, for instance.
Secure the adapter firmly to the bottom or other surface
of a reinforcing member made of channel steel where
dust and other foreign matter will not accumulate.
(Refer to page 24.)
Secure the adapter firmly so that there will be no chance
that it will fall off or fall down.
Secure it using a strength which can withstand the mass
(approx. 320 g [0.71 lbs.]) of the AC adapter.
Install the accessory AC adapter near the main power
outlet, and position it in such a way that its power plug
can be plugged into and unplugged from the outlet easily.
When connecting the AC adapter to a power outlet on the
ceiling or on any other surface where dust may collect, wipe
off the dust on the power plug at periodic intervals as an
anti‑tracking measure.
Power switch
This unit does not have a power switch. The power turns
on when its power plug is connected to a power outlet.
When the power is turned on, the pan, tilt, zoom and
focusing operations are performed. Before proceeding with
maintenance, be absolutely sure to disconnect the power
plug from the power outlet.
Connecting the power cable
Be absolutely sure to connect the power cable of the
AC adapter through a circuit breaker using one of the
following methods.
(1) Connect the power cable through a power control unit.
(2) Connect the power cable to a circuit breaker in a
power distribution panel with a contact distance of
3.0 mm or more.
Use a circuit breaker which is capable of shutting
off all the poles of the main power supply with the
exception of the protective ground conductor.
(3) Install the AC adapter near the power outlet, and
connect it through the power plug.
Grounding
Before using the unit, check that the grounding wire has
been fastened securely.
Check the grounding resistance (less than 100 ) of the
grounding terminal.
When the power plug is to be converted into a 2‑pin plug
for use, first consult with your dealer. Then use a plug
adapter which is equipped with a grounding terminal, and be
absolutely sure to connect this terminal to ground.
In a case like this, be absolutely sure to make the
connection to ground before proceeding to connect the
power plug to the main power source.
Similarly, before the ground connection is
to be disconnected, be absolutely sure to
disconnect the power plug from the main
power source first.
If there is a possibility of noise interference
Either wire the cables so that the power cable (ceiling light
cord) of AC 100 V or more, and the signal cable are placed
at least 1 meter (3.3 ft.) apart. Alternatively run each cable
through its own metal conduit. (The metal conduits must be
grounded.)
Radio signal interference
If the unit is positioned near a TV or radio transmitting
antenna or a strong electrical field or magnetic field (such as
that generated by a motor, transformer or power lines), its
images may be distorted and/or the images may be affected
by noise.
When connecting the cables, ensure that the connector
areas will not be subject to any load.
Doing so may cause malfunctioning.
Allowing the generated heat to escape
This unit allows the heat generated inside to escape from its
surfaces.
Do not install the unit in a location where it will be
surrounded by walls or other surfaces and where heat will
be trapped.
