SAFETY
1. BE SURE TO GROUND!!
Be sure to ground the power supply unit before use.
2. DO NOT TOUCH ANY HIGH VOLTAGE TERMINALS!!
Do not operate the power supply unless someone who is familiar with the operation precede, the
hazards of high voltage, and the treatment for the electrical shock is present.
3. UNDERSTAND THE HAZARDS OF HIGH VOLTAGE!!
In case you let somebody operate the power supply for you, must be sure that he/she fully
understands the hazards of high voltage and the areas where never can be touched.
4. CUT OFF THE POWER BEFORE TOUCH THE UNIT!!
Cut off the power, and check that the power is OFF, before you touch the power supply.
Capacitors in the output circuit are still charged and dangerous even after the power has been
cut off.Discharge all remaining high voltage by grounding them.
5. DISCONNECT THE INPUT LINES(AC LINES) !!
In case you need to touch the inside of the power supply following instruction manual, cut off
the power and disconnect the input lines(AC lines), and ground all the capacitors and high
voltage section.
Don’t remove the case or touch the inside of power supply unless so instructed in the
instruction manual.
6. OPERATE THE POWER SUPPLY WITH YOUR RIGHT HAND!!
In order to avoid the electric shock to your important organs, operate the power supply with
your right hand and keep your left hand off from the power supply.
This power supply unit generates high voltage and energy.
Electric shock may lead to death or serious injury.
Be sure to follow the instructions below and handle the unit with caution.

Caution
Do not install the unit upside down or
on a wrong side.
Insufficient heat release may cause
deterioration of parts, which may
generate smoke or set fire.
Do not use the unit in a place subject to
high temperature or in an enclosed,
limited area.
It not only hampers the unit from
achieving its performance but also
causes deterioration of parts leading to
smoking or burning.
Do not wipe the unit with chemicals
(such as thinner) or wet cloth.
It may allow water inside leading to
electric shock, electrical leak or burning.
Do not cover the vent holes of the unit.
Vent holes are provided to prevent
elevation of temperature inside.
Covering them not only hampers the unit
from achieving its performance but also
causes deterioration of parts, which may
generate smoke or set fire.
Do not install the unit and the remote
controller in a place subject to direct
cold air. Condensation may lead to
electrical leak/burning.
Do not install the unit in a place subject
to corrosive gas or liquid (such as a
place where chemicals are handled).
Deterioration of parts may cause
generation of smoke or burning.

RESCUE
1. Free victim from contact with live conductor quickly.
Avoid contact with neither live conductor nor victim’s body.
2. Shut off high voltage at once and ground the circuit. If high voltage cannot be turned off
quickly, ground the circuit to discharge, or cut high voltage line by an ax with dry wooden
handle. Be careful of electric flash.
3. If circuit cannot be broken or grounded, use a dry board, dry clothing, or other
nonconductor to free victim.
4. Call an ambulance immediately.
SYMPTOMS
NEVER TAKE ELECTRICALLY SHOCKED CONDITION AS DEATH.
Symptoms of electric shock may include unconsciousness, failure to breathe, absence of
pulse, pallor, and stiffness, as well as severe burns.
Whenever victim is not breathing properly, give artificial respiration(see next page).
TREATMENT
1. Start artificial respiration at scene of accident. Only in case victim’s or
operator’s life is endangered, remove victim to safe location nearby.
2. After starting artificial respiration, continue without loss of rhythm until victim start
breathing without help, or being passed to medical aid.
3. When operator change while giving artificial respiration, do so without losing the
rhythm of respiration.
4. After giving first aid, try to get a diagnosis by a doctor as soon as possible because
shock can cause internal burn, which can be lethal if left untreated.
AFTER VICTIM REVIVES
Be prepared to resume artificial respiration, as he may stop breathing again.
Keep victim warm and lying down until he or she has been conscious for at least thirty minutes.
First-aid procedures to be implemented in case of electrical shock

v
1. PLACE VICTIM
Place victim in face-upward position horizontally.
2. CLEAR THROAT
Turn head to one side quickly wipe out any fluid, mucus, or
foreign body from mouth and throat with fingers.
3. OPEN AIR PASSAGE
Tilt head back and extend neck to open air passage.
4. LIFT JAW FORWARD
Put thumb in victim’s mouth and grasp jaw firmly. Lift jaw
forward to pull tongue out of air passage. Do not hold or depress
tongue.
5. PINCH NOSTRILS CLOSED
With other hand pinch nostrils closed to prevent air leak.
6. BLOW AIR IN
Take a deep breath, seal victim’s open mouth and exhale firmly into
victim’s mouth until chest is seen to lift.
Make sure to open mouth widely to avoid air leakage.
7.REMOVE MOUTH AND CHECK
Check the sound of breathing out air and see normal breathing
when releasing mouth. If no sound, repeat from OPEN AIR
PASSAGE. Continue at a rate of 12 to 20 times per minute.
Quantity of air have to be increased gradually. Especially when victim is infant, be carefully not to be
too strong, not to blow in too much air.
Keep giving artificial respiration until victim start breathing without help, or being passed to medical
aid.

1-4 Points to be careful about in handling
・ For your safety connect the ground terminal of the chassis to EARTH securely
・ Use thicker (5SQ or thicker) and short wire for chassis grounding or load grounding, and
ground at one point of the ground.
・ Connect the shield wire of the output cable to the chassis side of the load.
(It will protect power supply or prohibit electrical shock from discharge at load)
・ DON’T TOUCH the load immediately after turning the output OFF. Before touching the
load, make sure that the Power ON/OFF switch of the unit is turned off and output
voltage is zero with power supply’s voltage monitor or another HV voltmeter.
How to GROUND
１－５ Troubleshooting
・In case there is no output voltage
１．Check if the proper input voltage is supplied to the power supply.
・ Power supply input voltage, AC 100-240V +/-10%, 50/60Hz single phase
２．Check if the connection of options are correct.

3-1 Operation
1) Make sure that the connection is done correctly (Refer to Page 2. [How to GROUND]),
and operate it. For your safety connect the ground terminal of power supply to the earth.
2) Connect the enclosed AC input cord to the outlet.
3) Make remote switch connection (Refer P6 c . remote switch)
4) Turn on the POWER ON/OFF switch. The meter comes on, and unit gets Stand-by mode.
At this status, HV is not applied on output terminal.
5) When turn on OUTPUT ON/OFF switch, the red LED comes on and the unit becomes
output possible state. If output voltage is set by output voltage potentiometer or remote
voltage program, the unit will output voltage. Be careful with setting output.
6) Turn the output voltage adjustable potentiometer to set the desired output voltage.
If you want to lock at a set voltage, move the locking lever to the direction indicated
below illustration.
7) To stop operation of the power supply, set the output voltage setting dial to zero (in
case the same voltage is to be used later again, leave it as it is), turn off the POWER
ON/OFF switch.
3-2 Protection Functions
a. Over current protection (O.C.P.)
This unit has incorporated an over current protection, and the output is to be cutoff
when the current reach to approx. 105% of maximum rated current.
Output voltage shall be recovered when overload is removed.
b. Over voltage protection (O.V.P.)
This unit has incorporated a protection against over voltage, and even at the time of
abnormality, it is limited at approx. 105% of the maximum rated voltage to protect the power
supply and load from damages.
