Precautions during Transportation

This section explains precautions that must be followed when transporting the 19-inch rack.
・ Before delivering the rack, confirm that the transport route is wider than the rack.
・ Use of a board may be necessary where the surface of the transport route is uneven..

rack
• Because the maximum weight including the rack can be about 1,000 kg, confirm beforehand that
there is no problem with the transport route.
Example: Type of floors on the transport route
Ensure that the floor has sufficient load capacity to hold the rack, and that the casters do
not sink into the surface of the floor or catch on the floor.
• When transporting the rack to an upper or lower floor of a building, confirm beforehand whether
an elevator is available for use. If an elevator is available for use, confirm that the rack weight
does not exceed the laden weight capacity of the elevator.
• When transporting the rack, push the lower part of the rack rather than the middle of the rack to
keep the rack from falling over. The barycentric position of the rack can be higher than the center
of the rack depending on where individual devices are installed.
Also, do not push on the rack sides. Doing so may cause the rack to fall over.
• Pushing against the center of the front door or the air vent opening may cause them to become
deformed. Move the rack by pushing against the door corners.
• Condensation will build up inside the devices installed in the rack if the rack is moved from a cold
location to a warm room.
Prevent the buildup of condensation in the room where the rack is installed by ensuring that the
room temperature does not increase faster than 15 ℃ per hour. See the following table for infor-
mation on condensation..
