2-4 Handling Precautions
As a guide, equipment (systems) using a high-voltage power supply of 750 V or more may occur failures
caused by the high voltage.
Although the unit is equipped with protection for instantaneous short circuit, it should not be operated in
the event of repeated short circuits with discharge.
Although all possible measures have been taken against noise, if you find hang-up or unintended
voltage output, turn off the input power once to reset the product.And, turn on the input power again
and restart the product. Meanwhile, send commands to gradually increase the output while confirming
the output voltage/current and checking any abnormality on displaying.
Before changing loads, turn off all equipment consisting of your system.
Confirm the input voltage that is displayed on the rear panel of the unit to enter the
correct voltage.
If an incorrect voltage is entered, the equipment could be damaged.
Wait at least 20 seconds after turning off the POWER switch before turning it on again.
Repeatedly turning the POWER switch ON and OFF at short intervals will cause a
breakdown of the inrush current limiting circuit, shortening the service life of the input
fuse, POWER switch, and other components.
* If the POWER switch is turned ON and OFF repeatedly at short intervals, an input
voltage drop error might occur to protect the internal circuitry.

Never place objects on top of the power supply unit.
Avoid using the unit in locations that are subject to dust and corrosive gas.
Do not install the unit in a place where condensation may occur.
Do not allow liquids or metals to get inside the power supply via ventilation holes or other
openings. Doing so could lead to breakdown, electric shock, or fire.
Do not store or use the product in a place where conductive dust, such as iron powder,
can enter through the air inlet/outlet.
Doing so may cause a short circuit, resulting in electric leakage, burnout, fire, or
malfunction.
The product is designed for a 19-inch rack. Support the chassis with the guide rails of a
rack when installing the unit. Never support the unit only with the mounting holes on the
front panel.
The handles on the front panel are used to change the direction of the unit or pull out the
unit mounted in a rack. Avoid any application that the entire weight of the unit is applied
to the handles on the front panel.
Install and use the unit in a horizontal orientation.
Secure a space at least 30 cm or more in front and back of the unit not to block air inlet
and outlet.
Secure openings for air inlet and outlet in an external cabinet as the same size as the
unit openings respectively.
When installing the unit in a closed cabinet, mount forced exhaust to prevent exhaust
heat from returning to the air inlet.
If dust collects in the air inlet, remove it immediately. It prevents the unit from cooling.
When doing work such as welding near the unit, disconnect all wires from the unit.
Ventilation2-5-2
As the front and back sides of the unit are air inlet and outlet for cooling air respectively, secure a space
for good ventilation to use the unit. Even securing a space of 30 cm or more, use it with sufficient air flow
without blocking the space.
If dust collects in the air inlet, remove it immediately.
If dust collects in the air inlet, it may result in malfunction due to less cooling.
Fan replacement2-5-3
The fan in this power supply has a limited service life. As it becomes worn and deteriorates with use, its
operation might become unstable. Note that the service life of the fan will vary greatly depending on the
usage environment (temperature, humidity and dust). To use this power supply for a long time, it is
necessary to replace the fan at regular intervals. Please contact Matsusada Precision for assistance in
replacing the fan. (A separate repair fee is required to replace the fan. Do not replace the fan by yourself
as it may cause electric shock.)
