Equipment damage
Be sure to follow the precautions below when installing the main unit. Otherwise,
the equipment may be damaged.
• Do not block ventilation slits.
• Avoid installing the equipment in a placed exposed to direct sunlight or near
equipment that becomes extremely hot.
• Avoid installing the equipment in a dusty place or a place directly exposed to
corrosive gas or salty air.
• Avoid installing the equipment in a placed exposed to strong vibration. Also,
install the equipment on a level surface so that it is stable.
• The grounding wire must be class 3 or higher. Connecting it with another
grounding wire for shared grounding may cause a malfunction. Be sure to use
a single grounding path for the grounding wire.
• Do not run any cable beneath any equipment. Also, prevent cables from
becoming taut. Never disconnect any power cable from the equipment while
power is being supplied to the equipment.
• Do not place anything on top of the main unit. Do not use the main unit as a
workspace.
• Avoid exposing the equipment to rapid changes in the ambient temperature,
such as a rapid increase during transport in winter. A rapid increase in the
ambient temperature causes moisture to condense in the equipment. Use the
equipment only after the difference between its temperature and the ambient
temperature is negligible.
• Avoid installing the equipment near a copy machine, air conditioner, or
welding machine, which is noisy.
• Take preventive action to minimize static electricity at the installation location.
Note that static electricity is easily generated in some carpets and can cause the
equipment to malfunction.
• Confirm that the power supply voltage and frequency during operation match
the rated values indicated on the equipment.
• Do not insert any object into an opening in the equipment. Components inside
the equipment use high voltage. Conductive foreign matter, such as a metal
object, inserted into the equipment, may cause a short circuit between
components, resulting in fire, electric shock, or equipment damage.
• For maintenance of the equipment, contact your authorized service personnel.
