SAFETY INSTRUCTIONS (Continued)
 Before you move this equipment, make sure you shut down the OS,
disconnect the plug of the power cord from the outlet, and wait for at least
one minute. If you do not, the HDDs and other devices may fail.
 When you transport or carry the equipment, pack it in the dedicated container
(container and packing materials used when the equipment was delivered).
If you use other container or packing materials, that may damage the equipment.
 Do not use damaged or broken dedicated container when you transport or
carry the equipment. If you do, that may damage the equipment.
 Do not route the interface cables, etc. (including cables for other devices such
as a PC) near the power cord. If you do, a failure or malfunction of the equipment
may result.
 Do not connect or disconnect an interface cable while the power for this
equipment or for the remote device is on. If you do, failure of the equipment
may result due to a short circuit between the power supply and the ground.
When an interface cable comes off while the power for the equipment is on,
shut down the OS and disconnect the power cord from the outlet.
Disconnecting the power cord from the outlet without shutting down the OS
might destroy the internal files.
 When you connect a cable for external contacts, make sure you connect the
cable to a connector for the external contacts (EXT). It is possible that a
voltage as high as 40 VDC can be applied to the cable through a relay load.
If you connect the cable to the wrong connector, that may cause failure of the
equipment.
 Performing emergency shutdown (that is, unplugging the power cord from
the outlet or shutting off the breaker without proper shutdown of the OS)
may cause the OS or applications not to work properly or may cause saved
data to be corrupted. Do not perform emergency shutdown unless you must
stop the system immediately due to some kind of error.
 If you turn off the power at the source of AC the power, the system may not
be able to recover automatically.
