Power Supply and Power Cord
Do not hold the power plug with wet hands.
Do not disconnect/connect the plug while your hands are wet, otherwise it may cause
an electric shock.
Do not connect the protective earthing conductor to a gas pipe.
Never connect the protective earthing conductor to a gas pipe; otherwise it may
cause a gas explosion.
Plug into a proper power source.
Use a proper wall outlet. Use of an improper power source may cause a fire or a
leak. Do not install the blade enclosure where you need an extension cord.
Use of a cord that does not meet the power specifications of the blade enclosure may
heat up the cord and cause a fire. The maximum power consumption per power unit
is 3000 VA. Note the capacity of a power unit when it is connected to CPU blades.
Do not connect many loads on one electrical outlet.
The electric current exceeding the rated flow overheats the outlet, which may cause a
fire.
Place the power supply tap in a place where it is noticeable and easy to
access.
Place the power supply tap in a place where it is noticeable and easy to access so that
power can be shut off in emergency.
Insert the power plug completely.
Heat generation resulting from a halfway inserted power plug (imperfect contact)
may cause a fire. Heat will also be generated if condensation is formed on dusty
blades of the halfway inserted plug, increasing the possibility of fire.
Use the proper power cord only
Use of an improper power cord may cause a fire when the electric current exceeds
the rated flow. Also, observe the following to prevent an electric shock or fire caused
by a damaged cord.
 Do not stretch the cord harness.
 Do not pinch the power cord.
 Do not bend the power cord.
 Keep chemicals away from the power cord.
 Do not twist the power cord.
 Do not place any object on the power cord.
 Do not bundle power cords.
 Do not alter, modify, or repair the power cord.
 Do not secure the power cord with staples or equivalents.
Do not use any damaged power cord. (Replace a damaged power cord with a new
one of the same specifications. Ask your sales representative for detailed information
on power code.)
