Voltage
lt is very dangerous to use an AC power source of high voltage
such as for an air conditioner,
A fire might be caused by such a connection.
© A DC power source can not be used.
Be sure to check the power source carefully, especially on a ship
or other place where DC is used.
Power cord protection
Avoid cuts, scratches or poor connection of the AC mains cord, as
this may result in fire or electric shock hazard.
Excessive bending, pulling or slicing of the cord should also be
avoided.
@ Do not pull on the cord when you are disconnecting the power, as
this could cause an electric shock. Grasp the plug firmly when you
disconnect the power supply.
® Never touch the plug with wet hands or a serious electric shock
could result.
