Caution
-
Distance between the external capacitor unit and power supply
unit must be secured more than 5mm.
-
It must be 30mm or less, since the noise is generated from the
wire which connects the external capacitor unit and power sup-
ply. It is necessary to twist the wire as short as possible.
-
It is necessary to use wires which are rated for voltage of 600V
or more.
-
It must be used with the external capacitor unit (CR-HUT).
-
For more information about the external capacitor unit and har-
ness (H-IN-25), please refer to the optional parts page.
¿
-Y
-
Option -Y units can adjust the output voltage by attached poten-
tiometer.
-
Refer to the adjustable range to the table 6.30 and table 6.31.

¡
To increase output voltage, turn a built-in potentiometer clockwise.
To decrease the output voltage, turn it counterclockwise.
¡
Please take care when you adjust output voltage by potentiom-
eter, because there is possibility of electric shock and breakdown
when contacting to other internal circuit by electrically conductive
tool.
