No. Name Necessary condition
2
Supply source (electrical
feeder line)
•
It is a single-phased AC current.
• Voltage is 200 to 240 V.
3 Ground cable (Note. 2)
•
The ground cable must be grounded.
• The ground bar, etc. is buried in the ground for grounding.
4
External power supply input-
ting cable
•
Prepare 2 cables which meet the following conditions.
1.
It is 3-core cable.
2.
Nominal cross-sectional area of 1-core is 5 mm
2
.
3.
It is cabtyre cable type.
4.
Length is 30 m or less (Note. 3).
Note. 1: Ground fault interrupter is installed so that the persons on the machine are protected from the electric
shock in case the supplied electric current is leaked to the machine.
Note. 2: Ground cable is buried in the ground for the same reason as (Note. 1).
Note. 3: This is to prevent the voltage drop.
FABRICATE EXTERNAL POWER SUPPLY CABLE
External power supply input cable can be fabricated at site according to the local need, but here we provide
some guidance for you to conform to.
Fabricate the cable in accordance with the following procedure.
Procedure for fabrication

CAUTION
• Always solder the connections between the connector and the core wire.
• Fit a rubber tube or a tape on the soldering parts for insulation to prevent short circuit caused by
contact between conductors.
• Always use 175-06-32781 for the plug. If any other plug is used, it will be impossible to connect to
the external power supply input (receptacle).
1.
Locally purchase the 3-core chloroprene sheathed cabtyre cable.
• Appropriate nominal cross-sectional area of the single core is 5 to 8 mm
2
.
• For the withstand voltage performance, the cable should be resistant against 3000 V for 1 minute.
• Length of the cable should be 30 m or less in order to prevent the voltage drop.
• Cross section as an example
(1) Chloroprene sheathe
(2) Conductor
(3) Paper tape
(4) Insulator
2.
Connect the input plug (5) for the machine body side
(175-06-37871), terminal (8) (08860-00404), and water-
proof cover (13) (17A-06-23330) to the tip of the cable
(14).
1) Put the cable (14) through the waterproof cover (13).
2) Connect the 3-core wires (10) of the cable (14) and the connecting wire of the terminal (8) by soldering.
3) Fit a rubber tube or the tape (11) on the core wires (10) and the connecting wire of the terminal (8) for
insulation.
