Caution
(1) Distance between the external capacitor unit and power supply
unit must be secured more than 5mm.
(2) It must be 30mm or less, since the noise is generated from the
wire which is connecting the external capacitor unit and power
supply. And, it is necessary to twist the wire as short as possible.
(3) It is necessary to use wires which rated voltage is 600V or more.
(4) It must be used with the external capacitor unit (CR-HUT).
(5) For more information about the external capacitor unit and har-
ness, please refer to Optional Parts.
7.2 Others
¡
This power supply is the rugged PCB type. Do not drop conduc-
tive objects in the power supply.
¡
At light load, there remains high voltage inside the power supply
for a few minutes after power OFF.
So, at maintenance, take care about electric shock.
¡
This power supply is manufactured by SMD technology. The
stress to PCB like twisting or bending causes the defect of the
unit, so handle the unit with care.
-
Tighten all the screws in the screw hole.
-
Install it so that PCB may become parallel to the clamp face.
-
Avoid the impact such as drops.
¡
While turning on the electricity, and for a while after turning off,
please don’t touch the inside of a power supply because there are
some hot parts in that.
¡
When a mass capacitor is connected with the output terminal (load
side), the output might become the stop or an unstable operation.
Please contact us for details when you connect the capacitor.
