1-4 Caution for handling 

1.

Make the setting of an output voltage to zero (0). Turn off the HV ON/OFF switch. 

2.

Make sure that the output voltage is zero with the output voltmeter of this unit. 

3.

Turn off the POWER ON/OFF switch. 

4.

Ground the output for more than 10 seconds, and make sure that the output voltage is  zero 

at  another HV voltmeter. It is especially dangerous when a capacitive load is connected or a 
long cable is attached there to. 

5.

Make it a rule to touch loads with right hand. 

・For safer operation, be sure to ground the ground terminal of power supply at 

One point on the ground. 

・

Make sure to connect the GROUND terminal correctly as shown above. Improper grounding 
is dangerous and may cause an electric shock or damage the power supply. 

・

In case output short circuit or discharging is expected, use shorter and thicker grounding 
wire.
