Caution for AC line Voltage Selection

注意：電源電圧の変更

The unit can be used with differnt voltage of 100V,120V,230V.
(Use the Japanese domestic model at 100V only, and never change the voltage in Japan.)
Refer the photo and illustration for the wiring on the junction terminal as shown below,
and have to select the correct fuse and power supply cord.

電源電圧は、100V､120V､230V に対応できますが以下はその方法を示します。
（日本国内は100V仕様ですので、この電圧以外の変更は出来ません）
電源電圧の変更をする場合は、フューズ、電源コードは以下の指定されたコードを使用します。
