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.

Precautions for Use (Be Sure to Read)
Express5800/E120d-1 User’s Guide
16
CAUTION
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
Do not pinch the power cord
Keep chemicals away from the power cord
Do not place any object on the power cord
Do not alter, modify, or repair the power cord
Do not use a damaged power cord (replace the
damaged power cord with a power cord of the
same standard. For information on replacing the
power cord, contact the store where you
purchased the product or a maintenance service
company)
Preparation of Power Strip
Prepare Power Strip or socket-outlet near the equipment and it shall be easily accessible, otherwise it is
hard to disconnect AC power promptly.

Precautions for Use (Be Sure to Read)
Express5800/E120d-1 User’s Guide 17
CAUTION
Do not use the attached power cord for any other devices or usage.
The power cord that comes with your server is designed aiming to connect with this server and to use with
the server, and its safety has been tested. Do not use the attached power cord for any other purpose.
Doing so may cause a fire or an electric shock.
Do not pull out a cable by gripping the cable part.
Pull a cable straight out by gripping the connector part. Pulling a cable by gripping the cable part or
applying extra pressure to the connector part may damage the cable part, which may cause a fire or
electric shock.
