SAFETY
1. BE SURE TO GROUND!!
Be sure to ground the unit before use.
2. DO NOT TOUCH ANY HIGH VOLTAGE TERMINALS!!
When operate the unit, don’t touch the terminals of high voltage output and control cable of
power supply which is connected to the unit to avoid electric shock. When running, very high
voltage is charged at the terminals of power supply, which can cause electrocution.
3. UNDERSTAND THE HAZARDS OF HIGH VOLTAGE!!
In case you let somebody operate the unit 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 unit. 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 unit 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 unit unless so instructed in the instruction
manual.
6. OPERATE THE UNIT WITH YOUR RIGHT HAND!!
In order to avoid the electric shock to your important organs, operate the unit with your right hand and
keep your left hand off from the unit.
Power supplies which is connected to the unit generate 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.

ii
Various symbols are used in this instruction manual and on the product for ensuring safety.
What will be caused by ignoring the instructions given with the symbols or by improper handling
are classified as shown below. Read carefully and understand the descriptions before
proceeding to the main body of this manual.

Warning
Do not touch the output terminal or the
leads or load connected to it while the
unit is in operation or immediately after it
is stopped. Otherwise it may cause
electric shock or injury.
・
Do not install the unit in a place subject
to steam or water vapor.
Otherwise it may cause poor insulation
and lead to fire or electric shock.
Do not install the unit in a place subject
to dew condensation.
Otherwise it may cause electric shock.
Do not modify or damage the cables.
Otherwise it may cause electric shock.
Be sure to ground the unit to avoid a rare
possibility of electric shock.
Otherwise it may lead to fire, electric
shock or injury.
Do not place any object on the unit.
Dangerous situations may occur if the
object drops or falls.
Do not put any object in the unit.
It may cause damage.
Do not disassemble, remodel or repair the
unit. High voltage may be built up inside,
which may cause electric shock.
Disassembly, remodeling or repair hamper
ensuring of safety and may lead to
dangerous situations.
Do not install the unit outdoors or in a
place subject to leaking of water, flood
or snow.
Otherwise it may cause electric shock.

■After reading this manual, be sure to store it in a place convenient for the users so that it can be
referred to at anytime.
！ 
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
Artificial respiration
7.Remove mouth and
check
6.Blow air in
3.Open air
passage
2.Clear throat
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.

Note
It must be covered with a cap that each optical fiber cable connectors are not in use.
We recommend that AC power source connecting this unit is differing from high
voltage power supplies’. That prevents CO series confusing, which the noise
supplies to AC power line as the output of high voltage power supplies is shorted.
