Power and Earth Connection Cautions
The power specifications are listed below. Connect the power plug only to a properly rated
power outlet. Otherwise, it can cause fire or electric shocks. If in doubt, contact our Cus-
tomer Support Center.
●Rated voltage 220-240 V
●Rated frequency 50/60 Hz
Ensure that the plug connection is free of dust. In a damp environment, a contaminated
connector can draw a non-negligible amount of current that can generate heat and eventu-
ally cause fire over an extended period of time.
Always use the power cord provided with your machine. When an extension power cord is
required, always use a properly rated cord.
●In Japan: “125 V/15 A”
●In other countries: Contact our Customer Support Center.
If you use a cord with an unspecified current rating, the machine or plug may emit smoke or
become hot to the touch externally.
Do not attempt to rework, pull, bend, chafe or otherwise damage the power cord. Do not
place a heavy object on the cord. A damaged cord can cause fire or electric shocks.
Never touch a power cord with wet hands. Danger of electric shock exists.
If the power cord is broken or insulated wires are exposed, contact our Customer Support
Center for a replacement. Using a damaged cord can cause fire or electric shocks.
Stop operation immediately if your machine produces smoke, excessive heat, unusual noise,
or smell, or if water is spilt onto the machine. These conditions can cause fire. Immediately
switch off and unplug the machine, and contact our Customer Support Center.
To prevent fire or electric shocks, follow the instruction below based on your machine con-
figuration. If in doubt, contact our Customer Support Center.
●If your machine is a 220-240 V model, there is no need to attach a separate earth line
since the earth connection is incorporated in the power line. Plug it into a properly rated
outlet.
●If your machine is a 100 or 110 V model, use the green earth wire bundled with the power
cord, located at the rear of the machine.
The earth wire must be connected to one of the following conductors:
- Earth terminal of the specified power outlet
- A piece of copper buried in the earth 650 mm or deeper
- Earth terminal with Class D* earthing.
*Class D is the regulation for Japan only.
Never connect the earth wire to any of the following:
●Gas pipe, which can be ignited and explode
●Telephone line earth wire or lightning rod, which can draw an excessive electric current if
hit by lightning
●Water faucet or pipe whose electrical conductivity is broken by a non-metal part
