Safety Symbol and Message Conventions
Safety symbols and messages described below are used in this manual to prevent bodily injury and property
damage which could result from mishandling. Before operating your product, read this manual first and
understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards.
Do not leave the unit upside-down where it could be exposed to the
rain or elements. Water in the unit may cause shorts that could result
in fire or electrical shock.
WARNING
When Installing the Unit
• Use the unit only with the voltage specified on the unit. Using a voltage higher than that which is specified
may result in fire or electric shock.
• Do not cut, kink, otherwise damage nor modify the power supply cord. In addition, avoid using the power
cord in close proximity to heaters, and never place heavy objects (including the unit itself) on the power cord,
as doing so may result in fire or electric shock.
• Avoid installing the unit in unstable locations, such as on a rickety or slanted surface. Failure to do so may
result in the unit falling and possibly causing personal injury.
• Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket.
Doing otherwise may result in the unit falling down and causing personal injury and/or property damage.
• Only use the unit's dedicated mounting hardware. The use of mounting hardware not designated could result
in the unit falling and possibly causing personal injury.
• Do not install the unit in the following locations to avoid a traffic accident or personal injury.
Locations which block the driving of the car.
Locations where the traffic signal or road sign is hard to be seen.
• To prevent lightning strikes, install the unit at least five meters away from a lightning rod, and yet within the
protective range (angle of 45°) of the lightning conductor. Lightning strikes may cause a fire, electric shock
or personal injury.
• When installing the unit in the snowy area, take appropriate measures to prevent snow from lying on the
unit. If the snow lies on the unit, the unit may fall, causing personal injuries.
• Be sure that at least two persons are available to install the unit. Failure to do so could result in personal
injury.
• Do not use any methods other than specified to mount the bracket. Extreme force is applied to the unit and
the unit could fall off, possibly resulting in personal injuries.
• Attach the safety wire to the unit. If not attached, the unit could fall off, resulting in personal injury.
• Use nuts and bolts that are appropriate for the ceiling's or wall's structure and composition. Failure to do so
may cause the unit to fall, resulting in material damage and possible personal injury.
• Tighten each nut and bolt securely. Ensure that the bracket has no loose joints after installation to prevent
accidents that could result in personal injury.
Indicates a potentially hazardous situation which, if mishandled, could
result in death or serious personal injury. WARNING
