Provide proper ground connection to the HV module. In order to prevent electrical breakdown,
ensure that the distance between the bottom of HV module and the surface below is more than
6 mm.
Connect the +24V DC power supply to the HV module. The DC power supply must be able to
provide the maximum current as per 2.2

Turn on +24V DC power supply. “+24 V” LED indicator (
#2
in
Table 4
) should light.
Set the output voltage using the potentiometer (
#5
in
Figure 2
). Ways to control of the output
voltage:
1.
Measure the output high voltage directly if your control equipment is capable of
measuring high voltage.
2.
Alternatively, measure the voltage between points
#3
and
#6
in
Figure 2
. The output is
1:1000 voltage divider.
The pins
#3
and
#4
in
Figure 2
can be used to turn off HV output. HV output is off if these pins
are shorted together.
Turn off +24V DC power supply.
Connect the load to HV power supply output. Check that the connection cables are firmly
attached.
Switch the DC power on. Measure the voltage on DC supply input of HV power supply.
If the measured voltage is below +23.5V, use thicker cables to connect HV module to DC power
supply, or increase the DC power supply voltage.
HV supply has on-board overheat protection. If temperature exceeds 50°C, HV supply
automatically switches off; this is indicated by the LED (
#2
in
Figure 2
), which will be off.
To bring HV supply back to operation, lower ambient temperature below 50°C and cycle (switch
off and back on) the DC supply.
