9. Operation:
WARNING
THIS EQUIPMENT GENERATES DANGEROUS VOLTAGES THAT MAY BE FATAL.
PROPER GROUNDING OF ALL HIGH VOLTAGE EQUIPMENT IS ESSENTIAL.
WARNING
THIS EQUIPMENT IS PERMANENTLY CONNECTED THEREFORE IT SHALL OPERATE IN
BUILDINGS WITH A SWITCH OR CIRCUIT BREAKER. THIS EQUIPMENT MUST BE
INSTALLED IN CLOSE PROXIMITY OF THE SWITCH OR CIRCUIT BREAKER WITHIN
EASY REACH OF OPERATOR. THIS SWITCH OR CIRCUIT BREAKER SHALL BE MARKED
AS THE DISCONNECTING DEVICE FOR THE POWER SUPPLY.
CAUTION
BEFORE CONNECTING THE POWER SUPPLY TO THE AC SUPPLY, FOLLOW THIS
STEP-BY-STEP PROCEDURE.
FAILURE TO FOLLOW THESE PROCEDURES MAY VOID THE WARRANTY AND WILL
RESULT IN SAFETY VIOLATION.
Step 1
Turn the power switch at the rear of the power supply to off (0) position.
Step 2
Attach the AC power cord to the power supply and plug the other end to the wall socket.
Step 3
Attach the high voltage output cable to the load. The cable used should be shielded with a wire
braid that functions as the high voltage return. Make sure sufficient clearance and creepage
exists from the live conductor of the cable to high voltage return.
Step 4
Attach the mating plug on the high voltage cable to the HV output receptacle on the supply and
hand tighten. Make absolutely sure that a good high voltage output and high voltage return
connection is made between the supply and the load.
Step 5
The chassis of the high voltage power supply and high voltage cable shield must be solidly
grounded through AC power cord. Check chassis to ground and shield to ground with an
Ohmmeter to ensure reliable grounding.

Step 6
For initial turn-on, adjust the programming potentiometer to counter clockwise position until
after the potentiometer driven switch clicks. At that position, Bipolar HV Power Supply DC input
is off and programmed output high voltage is at 0V.
Step 7
Turn on the AC input switch located at the rear of the power supply.
Step 8
Turn the potentiometer clockwise slowly. When the potentiometer driven switch clicks, red LED
should be lit, indicating power to the Bipolar HV Power Supply is on.
Step 9
Digital display panel indicates actual output voltage when the red LED is on.
Turn the potentiometer clockwise slowly, output voltage increases as indicated by the output
voltage digital display panel.
Note the potentiometer has 300 degree rotation to change output voltage from 0V to an
absolute value of 30kV (full scale)
Step 10
To change polarity of the output voltage without changing the absolute value, use polarity
select switch. Output voltage will reduce gradually then ramp to the voltage of the opposite
polarity.
Step 11
To switch off the high voltage power supply, turn the potentiometer to full counter clockwise
position until the red LED on front panel is off. Switch off AC power switch at the rear of the
power supply.
WARNING
AFTER SWITCHING OFF, DO NOT HANDLE THE LOAD UNTIL THE POWER SUPPLY AND
LOAD CAPACITANCES HAVE BEEN DISCHARGED.
WARNING
The digital display of the power supply does not read the output voltage when the AC power
supply is disconnected or potentiometer switch is at off position, even if a high voltage charge
still exists across the load.
WARNING
Three HV outputs are internally connected in parallel. They are either on or off together.
