SAFETY
Equipment is designed to be safe under normal environmental conditions according to 1.4.1.
61010-1@IEC:2010 (Safety requirements for electrical equipment, control and laboratory use):
1. indoor use;
2. altitude up to 2000 m;
3. temperature 5˚C to 35˚C;
4. maximum relative humidity 80% for temperatures up to 31˚C decreasing linearly to 50%
relative humidity at 35˚C;
5. POLLUTION degree 1: no POLLUTION or only dry, non-conductive POLLUTTION occurs.
Warning:
The safety of the system incorporating HV power supply is the responsibility of
the assembler of the system.
Operating the power supply is allowed to persons acquainted with the operation manual and
having permission to deal with voltages over 1000 V.
Do not remove unit covers while power cable is connected to the mains (if applicable).
WARNING
Direct contact with the exposed inner parts of the system when it is powered
may cause human injuries or death.
Do not operate the unit until it is grounded and the load is connected.
Do not use the unit if any defects have been detected.

QUICK START GUIDE
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 TECHNICAL SPECIFICATIONS.
Turn on +24V DC power supply.
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 #4 in Figure 2. This voltage
converts to output voltage approximately as 1V~1 kV.
Turn off +24V DC power supply.
Connect the HV supply load. Check that the connection cables are firmly attached.
HV output can be turned off when pins #4 and #6 in Figure 3 are interconnected.

CAN-USB converter is recommended for operation. It can be ordered from Eksma Optics. It
comes together with software and a set of connection cables.
Figure 4. CAN-USB converter
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 CAN cable to connector (#9 in Figure 3) from USB-CAN converter and USB cable
between USB-CAN converter and PC.
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 TECHNICAL SPECIFICATIONS.
Turn on +24V DC power supply. Use Control panel application to control via PC. It gives
possibility to turn ON/OFF and set high voltage output as well as to read-out actual status.

Figure 5. Control panel application
Use CANBrowser software to read-out actual status of HV power supply and save CSV file while
need for technical service or consultation of manufacturer. CSV file includes list of CAN control
registers and actual settings.
Connect the load. Check that the connection cables are firmly attached. Turn on HV supply via
CAN Browser or Control panel application.
