[For Ce And General Export, High Voltage]; Setting Of The Power Voltage Specifications - JUKI MOL-254 Engineer's Manual

(2) [For CE and general export, high voltage]

1) Setting of the power voltage specifications

○ Fix the brown wire with a marker printed "SEL" which is to be changed to the power tap to be used from
among the transformer taps (8P bar terminal borad) in the control box to the power tap section to be
used.
Indication of the tap is printed on the facing wire on the terminal board.
Example : 380V → 220V
0V
0V
Black
* Note : Never change the blue wire with the marker of 220V since it is for the main shaft motor
power.
○ Set the thermal trip set value of the power switch.
Open the cover of the power switch and set the thermal set value.
For the single phase power voltage, 220, 230 or 240V, set the thermal set value to the maximum 4.0,
and for the 3-phase power voltage, 380 or 400V, set the value to the minimum 2.5.
