Brief guide for commissioning power supplies of the series energy and energy installation

A guide for the quick commissioning and replacement of power supplies in existing plants. In addition, you will need the type-dependent manual consisting of data sheet and description.

Installation and cabling

  • Do not cover side and rear air openings.
  • For all connections a sufficient cross-section and a professional processing is required. Please refer to chapter 2.2* of the description.
  • The mains connection to X1 must always be carried out with a protective conductor.
  • For grounded output voltage, the earthing contact of load connection X2 must be used.
  • Sense leads should only be connected if they are required, otherwise they should be left unconnected.

Condition as delivered

  • Operation mode "LOCAL" is preset (operation via HMI). See chapter*.
  • Active interface is USB with 57600 Baud or with devices with an interface option (/AN or /LAN) the respective optional interface.
  • When the factory setting is loaded (in operation mode "CONFIG"), the interface configuration is also reset, see chapter 3.3.7*.
  • Memory bank "0" with the values specified for U, I and P is active. At delivery the maximum values for V, C and P are set.


  • If the power supply has an HMI (Human Machine Interface), it can be operated using the HMI as long as it is set to control mode "LOCAL". See also:
    • Chapter 3.2* describes the various HMI and DIP switches.
    • Chapter 3.2.2* describes the menu navigation.
    • Appendix A1* shows the menu structure for operation mode "CONFIG".
    • Appendix A2* shows the menu structure for the operation modes "STANDARD" (STD) and "LAB".
    • Appendix A3* shows the menu structure for operation mode "SEQUENCE".
  • In control mode "REMOTE" the device is operated using software commands. Chapter 3.4* describes the different interface configurations and commands.
  • The power supplies can be operated very easily via the RS232, USB and LAN interfaces using the free LabVIEW application DemoApp2 . Operation using DemoApp2 works in any operation or control mode, regardless of whether the power supply has an HMI.


  • With activated CAN interface, the "RUN" and "ERROR" LEDs indicate the status of the CAN interface according to CiA303-3.
  • With the CAN interface not activated:
    • If the green LED "OUT" is lit permanently, the output is active.
    • If the red LED "FAIL" is lit permanently, an error has occurred. On units with display the display shows an error message in plain text.
    • If the green LED "OUT" flashes, the activation of the output is not complete. Both enable inputs must be energized and all "STANDBY/ON" switches must be set to "ON".
    • If the red LED "FAIL" flashes, the software enable (command: "OUT 1") is missing to activate the output.

Switching on

  • Set all sliding switches "STANDBY/ON" to "STANDBY".
  • Apply the mains voltage so that the power supply boots up.
  • After the boot process, set the wanted parameters according to your application.
  • Set all sliding switches "STANDBY/ON" to "ON".
  • All enable inputs on connector X4 have to be energized. Each power supply comes with a D-Sub connector with all necessary bridges, which only needs to be plugged in. We recommend storing the plug directly at the device.
    • In control mode "LOCAL" (local operation via HMI) the output is now active.
    • In control mode "REMOTE" (remote operation via interfaces) the software enable must also be applied with the command "OUT 1" in order to activate the output.

Note: Each time the control mode is changed from "REMOTE" to "LOCAL", the output needs to be enabled using all "STANDBY/ON" switches or both enable inputs on X4 (toggle off/on).


  • To remotely control the power supply:
    • the desired interface must be selected and configured
    • control mode "REMOTE" must be selected
  • For power supplies with HMI (integrated or external), the interface is selected and configured in operation mode "CONFIG" on the HMI. The menu structure can be found in Appendix A1*. Value changes are saved immediately.
  • For power supplies without HMI:
    • The selection and configuration of the interfaces is made with the DIP switches. Please observe the imprint on the housing of the power supply.
    • With DIP switch 1 in the block of 4 it is possible to switch between the configuration via DIP switches and the settings in the EEPROM.
    • CAN addresses, which go beyond the address space that can be set with the DIP switches, can only be set via an optional HMI and the interface configuration source must be set to EEPROM.
  • The allocation of the node address Node-ID (default: 128) is optional and is only intended for the operation of several devices on a common serial bus. The node number can also be set using the ASCII command "NODE".

USB interface

  • For connection via USB, a driver may be necessary, which provides a virtual COM port. See the page USB driver  for the driver and a usage guide.

Analog interface (option /AN)

  • When the analog interface is active, the last selected digital interface remains active in order to be able to program and monitor all functions apart from the set values for voltage and current.
  • The analog monitor outputs always report the actual values for voltage and current, regardless of the selected interface.

LAN interface (option /LAN)

  • A Lantronix XPort is integrated in power supplies with the /LAN option.
  • Two software packages are available for setting up the LAN connection:
    • Lantronix Device Installer(manual IP assignment)
    • Lantronix COMPort Redirector(setting up a virtual COM port)
  • The default setting for IP address distribution is DHCP. Without an accessible DHCP server, the XPort chooses an address in the APIPA address range
  • See the page LAN driver  for the driver and a usage guide.
