1-2-2. Notes on Installation
CAUTION
To avoid an injury, do not install the unit on an unstable table.
Ventilation, and Work Space for Servicing
• Do not block the air exhaust sections (rear panel) and the air vent (bottom of front side and both the right and left
sides).
• Do not install the unit with the feet (on the four corners of the bottom plate) removed.
• In order to make a unit with good ventilation, ensure sufficient clearance around the unit.
• Be sure to provide 2 cm or more space to both the right and left sides and the top of the unit, and 25 cm or more
space behind the unit.
• Do not stack any equipment on this unit.
Tip
When the unit is installed on flat surface like a desk, provide 2 cm or more space to both right and left sides of the unit.
Providing 40 cm or more space above the unit is recommended considering service operations.

1-2-3. To Mount the Unit in a Rack
Notes on Rack Mounting
• Heat generation by neighboring units could lead to a failure of the unit. Check that the temperature inside the rack
is within the range of specified operating temperature of the unit.
• Do not cover the exhaust port or ventilation holes (lower front, right and left sides).
• When installing units side by side, leave 1 cm or more of space between the sides of the units. Blocking the air
intake will damage the unit.
• Leave 25 cm or more of space to the rear of the unit.
• Use a commercially available rack mount shelf.
Select an appropriate shelf taking size and weight of the unit into consideration.
• Never remove the top panel, bottom panel, handle, or legs of the unit when installing.
• Use adequately long cables for connection of the connector panel, considering that the unit is pulled out from the
rack.
Note
After rack mounting, check that the temperature inside the rack is within the range of 5 ℃ through 35 ℃.
