1-4Points to be careful about in handling and care
WHEN TOUCHING LOAD AFTER TURNING OFF A HIGH VOLTAGE
1. Make the setting of an output voltage to zero (0). Set the INTLK (Interlock*) switch setting to output off.
*This is not function that satisfies the requirements of CE, UL.
2. Turn the input voltage (24 VDC) OFF.
3. Earthing an output for longer than 10 seconds, check and confirm that the voltage is zero
at another high voltage voltmeter. It is especially dangerous that the load is capacitate
or a long cable is attached there to.
4. Make it a rule to touch load with right hand.
How to GROUND
・For safe operation, be sure to ground the ground terminal of power supply at one point
on the ground.
If the Load frame is not grounded
If the Load frame is grounded
・Be sure to complete grounding as shown above. Inadequate grounding may lead to
electric shock of damage to the power supply unit, which is dangerous.
・If there is a possibility of development of a short-circuiting of load or discharging, make
larger and shorter the grounding conductor.
IN ORDER TO INSURE SAFETY THE GROUND
TERMINAL SHOULD BE EARTHED AT ALL TIME.
Wires should be :
・more than 5SQ
・less than about 2m
・not bared

FOR SAFER OPERATION
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 output 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.
1-5What to do before calling for service
・In case no output voltage is generated.
1. Check whether or not a specified voltage has been inputted.
・Input Voltage +24Vdc ±10%
・Control voltage 0 –10V at the time of controlling over external voltage.
・Control voltage 0 –10V at the time of controlling over external current.
・In case a discharging noise is generated near a high voltage output block :
1. Check whether or not plug block of the high voltage connector (part shown with an arrow mark
hereunder) is stained. If used with plug stained, a discharging phenomenon will develop sometimes inside
connector sometimes. Wiping off stains with such liquids as alcohol, dry it fully and use it.
