Power Supply And Power Cord Use - NEC Express5800 Series User Manual

Power supply and power cord use

Do not hold the power plug with a wet hand.
Do not disconnect/connect the plug while your hands are wet. Failure to follow this warning may cause an
electric shock.
Do not connect the ground wire to a gas pipe.
Never connect the ground wire to a gas pipe. Failure to follow this warning may cause a gas explosion.
Plug in to a proper power source.
Use a grounded outlet with the specified voltage. Use of an outlet with a voltage other than that specified
causes fire and electrical leakage. Do not install the server in any environment that requires an extension
cord. Connecting to a cord that does not conform to the power supply specs of the server causes
overheating, resulting in fire.
If you want to use an AC cord set with a ground wire of class 0I, be sure to connect the ground wire before
inserting the power plug into the outlet. Before disconnecting the ground wire, be sure to disconnect the
power plug from the output.
Do not connect many cords into a single outlet by using extension cords.
The electric current exceeding the rated flow overheats the outlet, which may cause a fire.
Insert the power plug into the outlet as far as it goes.
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.
Do not use any unauthorized interface cable.
Use only the interface cables provided with the server. Electric current that exceeds the amount allowed
could cause fire. Also, observe the following precautions to prevent electrical shock or fire caused by a
damaged power cord.
• Do not stretch the cord harness
• Do not bend the power cord.
• Do not twist the power cord
• Do not step on the power cord.
• Uncoil the power cord before use
• Do not secure the power cord with staples or
equivalents
