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 driver and 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 the proper ground connection to ground screw (#8) of HV power supply.
Connect the +48 VDC power supply to the HV power supply. See Table 3 for requirements.
HV level may be tuned by:
1. Using internal (#1) trimmer potentiometer. Output voltage and current control is
available on test point TP OUT connector pins (#6).
2. Using CAN or RS232, see CHAPTER 6 CONTROL VIA CAN/RS232 for details.
3. HV output can be switched off by connecting pin 1 of connector CAN/RS232 (#7) to GND
(pins 5, 6).
Figure 5. ON/OFF control input
Switch the DC power supply off. Connect the load. Check that the connection cables are firmly
attached.

Switch the +48 VDC power on. Measure the voltage on +48 VDC input of HV power supply while
HV power supply is loaded.
If the voltage measured is below +47V, use thicker wires, or increase the DC supply voltage to
compensate voltage drop.

CONTROL VIA CAN/RS232
CAN-USB converter is recommended for operation. It can be ordered from Eksma Optics. It
comes together with „CAN Browser“ software and a set of required cables.
Figure 6. CAN-USB converter
1. Connect CAN-USB converter to PC and HV power supply by cables supplied.
2. Turn on +48V power supply.
3. Install and open CAN Browser.
4. Set required settings (see CHAPTER 7 CAN BROWSER ).
1. Connect HV power supply to PC by the RS232 cable supplied. Note: do not attempt using
ordinary RS232 cables. Some of them are not compatible with this series of HV power
supplies.
2. Turn on +48V power supply.
3. Install and open CAN Browser.
4. Set required settings (see CHAPTER 7 CAN BROWSER ).
5. Refer document “ASCII serial protocol description” for details.
