(3) CONNECTOR
<Precautions>
・ In order to connect a connector properly, you need to insert it with the proper
orientation and at the proper angle. If a connector is not inserted properly, the connection
may fail or malfunction.
・ Make sure there are no loose I/O cable connectors on the equipment.
(4) POWER SUPPLY
1. Power Voltage
<Required actions>
• Confirm that the voltage of the power input to the equipment is within the specified range
(100Vto240VAC). If the voltage of the power input is close to the upper or lower limit of
the specified range, you should treat it as you would a setting error of the input voltage
and ask the manager of the power facility to inspect the voltage output by the facility
2. Power Cord
<Precautions>
• The power cord that comes with the equipment is rated at the input voltage of 125 VAC.
When using this equipment at over 125 VAC, prepare the power cord fitting input voltage
and inspect the safeness of this equipment enough.
• Install D class grounding (previously known as third class grounding) defined in the
Technical Standard for Electrical Facilities of Japan in order to maintain normal
operation of electronic circuits containing highly integrated LSIs and protect device
from abnormal voltage caused by lightning or the like.
• Use a power cord with a 2-prong plug and a grounding pole. (See“1.7 Hardware
connection”.)
• When you connect the plug of the power cord to an outlet, make sure you use an outlet
with a neutral pole that is properly grounded. In addition, you must install and use an earth
leakage circuit breaker.
• If you use a power cord clamp to prevent accidental disconnection, give an extra length to
the power cord when you fix the cord, in order to allow the cord to be disconnected in an
emergency. Alternatively, install an emergency circuit breaker at the outlet side.
• Do not put any object on the power cord. In addition, do not install signal lines near the
power cord.
