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 and care
WHEN TOUCHING LOAD AFTER TURNING OFF THE OUTPUT
1. Make the setting of an output voltage to zero (0). Turn off the OUTPUT ON/OFF
switch.
2. Check and confirm that the voltage is zero at an output voltmeter of this unit.
3. Turn off the POWER ON/OFF switch.
4. Earthling an output for more than 10 seconds, check and confirm that the voltage is
zero with another high voltage meter. It is especially dangerous that the load is
capacitive or a long cable is used.
5. Make it a rule to touch load with right hand.
FOR SAFER OPEREATION
1. Laying an insulation plate which can withstand the voltage to be used on the floor on
which an operator stands, carry out the operation. If done so, it will be comparatively
safe.
2. When operating a power supply and load, do so with right hand with left hand put in the
pocket, taking care not to touch other objects.
3. After turning off the voltage (even if a long time has lapsed after turning off), if you
touch load, be sure to earth the output longer than 10 seconds.
１－５ What to do before calling service
In case no output
1. Check whether or not a specified voltage has been inputted.
100-120VAC 50/60Hz single phase of input voltage.
(For output power of 600W or higher, 200-240VAC 50/60Hz single phase)
2. Check whether or not a connection is correct.

１－６ Characteristics of bi-polar amplifier
Capacitive load
Capacitive load may cause oscillation when it is more than 100pF. In such case, insert 1Ω
(10μF)～1kΩ（1000pF）power resistance in series with the output. Be careful that the
frequency bandwidth is limited depending on the resistance inserted in series in series and
the capacity under capacitive load.
Inductive load
Some inductance of inductive load may cause resonance in CC mode.
In such cases, connect a C-R series circuit between output terminals to prevent
resonance.
Response speed
When accurate output waveforms are required, select a bi-polar amplifier with a frequency
bandwidth adequately higher than the used frequency. In case of using in sine waves, 3 to 5
times quick frequency bandwidth is required, and around 10 times quick one is required in
case of using in square waves in general. Inadequate bandwidth causes not only decrease in
the output amplitude but much difference between the input and output phase. Therefore
attention must be paid by using the product while monitoring the output waveforms.

Rising time
（Stepping time）:The responsivity is sometimes expressed by the rising time(as shown in
the drawing below). The rising time of a bi-polar amplifier at a response speed of
(=frequency bandwidth)
Fc(Hz) is generally acquired by “trap proximately 0.35/fc”
Falling time tf is the same as tr.
１－７ Connection Precaution
・Since minus on secondary side and common are internally connected, please use minus
common. Plus common cannot be used.
・Power supplies cannot be connected in parallel except for units with LMs option.
