12. Mains supply (IEC C20, max.16 A)
13. 4 x Load outputs (IEC C13, max. 16 A, IEC-Lock)
Start-up the device
·Connect the power cord (IEC C19, max. 16A) to the mains supply. The cable con-
nectors are secured as regards their type against unintentional loosening. They must
be inserted up to the stop, otherwise there is no secure connection. The plug must
not wobble in the socket, or there is no tight connection.
·Plug the network cable into the Ethernet socket (RJ45).
·If required, setup a serial connection to the RS232 port.
·Insert the optional external sensors into the sensor connectors.
·Connect the consumers with the load outputs (IEC C13, max. 10A).
1.5 Overvoltage Protection
The device contains an overvoltage protection. The protection is based on input side
varistors with thermal fuse between phase (L) and neutral (N) to protect the internal
electronics and power ports with failure detection (permanently triggered thermal fuse).
The state of the protection is indicated on the front panel by a flash.
·An invisible flash means that the protection is active, a red flash symbolizes that the
overvoltage protection fails. (Revision 1 device)
·An green flash means that the protection is active, a red flash symbolizes that the
overvoltage protection fails. (Revision 2 device)
In addition, the status of the overvoltage protection can be seen on the Webpage
(HTTP) and acquired with SNMP. Each surge protection module is designed that it can
derive a practical unlimited number of voltage pulses in normal installation environ-
ments. In an environment with many energy rich surge pulses it can result in perman-
ent loss of function due to aging of the overvoltage protection element.

10
Expert Power Control 8021/8025 © 2021 GUDE Systems GmbH
Device Description
Recovering of the overvoltage protection function can only be performed by the
manufacturer of the device. In the normal case, the device will continue to work even
after the failure of the protective function.
A signaling via E-Mail, Syslog or SNMP trap occurs only once during operation, ex-
actly at the moment in which the protection fails. In addition, at the start up of the
device a message is generated, when the overvoltage protection is not active.

2 Operating
2.1 Operating the device directly
Port Switching
The current status of the output is indicated by the color of the LED. Red indicates that
the output is off, green shows that the output is on. On the device are the buttons "se-
lect" and "ok". If you press "select", you can select the following modes one by one:
1. At first, all LEDs flash green. If you press the "Ok" button for 4 seconds, all ports
are switched on. (If all ports are switched on, this is skipped).
2. After that, all LEDs flash red. If you hold the "Ok" button for 4 seconds, all ports will
be switched off. (If all ports are switched off, this will be skipped).
3. If you press "Select" again, the LED for the first output starts blinking, i.e. the output
is selected. Press "Select" again to select the next output. If you keep the "Ok" but-
ton pressed for one second, the state of the selected output will be toggled.
You can switch off in the front panel configuration that all ports with the modes
1 and 2 can be switched by pushbutton.
Display Information
If no port is selected manually, repeatedly pressing the "ok" button will show the IP-ad-
dress and the values of the external sensors on the display.
Status-LED
The Status LED shows the different states of the device:
·red: The device is not connected to the Ethernet.
·orange: The device is connected to the Ethernet and waits for data from the DHCP
server.
·green: The device is connected to the Ethernet and the TCP/IP settings are alloc-
ated.
·periodic blinking: The device is in Bootloader mode.
2.2 Control Panel
Access the web interface: http://"IP-address" and log-in.

Expert Power Control 8021/8025 © 2021 GUDE Systems GmbH
Operating
The web page provides an overview of the switching state, energy measurement val-
ues, as well as the external sensors, provided that they are connected. The number of
ports shown depends on the model. When a single port is clicked at the Expert Power
Control 8021/8025, a panel with buttons to control a single port appear:
The Port icon is green when the relay is closed, or red in the open state. An additional
small clock icon indicates that a timer is active. Timer can be activated by delay, reset
or batch mode.
An activated Watchdog is represented by an eye icon. An "X" means, that the address
that should be observed, could not be resolved. Two circular arrows show a booting
status.
In addition to the panel, the Expert Power Control 8025 shows the measured values
of the selected port:

17
Expert Power Control 8021/8025 © 2021 GUDE Systems GmbH
Operating
The ports can be switched manually with the "On" and "Off" buttons. If the port is
turned on, it can be turned off by pressing the "Reset" button, until after a delay it turns
itself on again. The delay time is determined by the parameter Reset Duration, which is
described in the chapter "Configuration - Power Ports ". The "Close" button dis-
solves the panel again.
Batchmode
Each individual port can be set for a selectable period of time to the state "switch on"
or "switch off". After the selected time they are automatically switched to the second
preselected state.
Optionally the device can be switched via a Perl script or external tools like wget. More
information is available on our support wiki at www.gude.info/wiki.
2.3 Maintenance
The actual device generation with IPv6 and SSL allows all maintenance functions in
the web interface to be carried out on the Maintenance Page .
Maintenance in the web interface
The following functions are available from the maintenance web page:
·Firmware Update
·Change the SSL certificate
·Load and save the configuration
·Restart the device
·Factory Reset
·Jump into the Bootloader
·Delete the DNS cache
Upload Firmware, Certificate or Configuration
On the Maintenance Page , select the required file with "Browse .." in the sections
"Firmware Update", "SSL Certificate Upload" or "Config Import File Upload" and press
"Upload". The file is now transferred to the update area of the device and the contents
are checked. Only now, pressing the "Apply" button will permanently update the data,
or abort with "Cancel".
Only one upload function can be initiated with a reboot, eg. you cannot transmit
firmware and configuration at the same time.

Expert Power Control 8021/8025 © 2021 GUDE Systems GmbH
Operating
If after a firmware update, the web page is not displayed correctly anymore, this
may be related to the interaction of Javascript with an outdated browser cache. If a
Ctrl-F5 does not help, it is recommended that you manually delete the cache in the
browser options. Alternatively, you can test start the browser in "private mode".
During a firmware update, old data formats are sometimes converted to new struc-
tures. If an older firmware is newly installed, the configuration data and the energy
meters may be lost! If the device then does not run correctly, please restore the factory
settings (e.g. from the Maintenance Page ).
Actions in Bootloader mode
If the web interface of the device is no longer accessible, the device can be put into
Bootloader mode (see chapter Bootloader activation ). The following functions can
be executed using the GBL_Conf.exe application:
·Set IPv4 address, net-mask and gateway
·Turn HTTP password on and off
·Turn IP-ACL on and off
·Factory Reset
·Jump into the bootloader (can be switched on and off)
·Restart the device
For devices with relays, entering or exiting the bootloader mode does not change
the state of the relays as long as the operating voltage is maintained.
The GBL_Conf.exe program is available free of charge on our website www.gude.info
and can also be found on the enclosed CD-ROM.
Interface GBL_Conf
To check the network settings with GBL_Conf.exe, start the program and choose "All
Devices" in the "Search" menu. From the list select the appropriate device. The lower
part of the left half of the window now shows the current network settings of the device.
If the IP address is displayed with the default settings (192.168.0.2), either no DHCP
server is present on the network, or there could be no free IP address assigned to it.

·Activate the Bootloader Mode (see Chapter Bootloader Mode) and choose in menu
"Search" the item "Bootloader-Mode Devices only"
·Enter the desired settings in the edit window and save them with "Save Config".
·Deactivate the boot loader mode for the changes to take effect. Select again "All
Devices" in the "Search" menu of GBL_Conf.exe.
The new network configuration is now displayed.
Factory Reset
The device can be reset to the factory default via the web interface from the Mainten-
ance Page or from the Bootloader mode (see chapter Bootloader activation ). All
TCP/IP settings are reset in this operation.
If a unit is set to factory defaults, an uploaded certificate or updated firmware will
be preserved.
2.3.1 Maintenance Page
This section provides access to important functions such as Firmware Update or Re-
start Device. It is advisable to set an HTTP password for this reason.
Firmware Update: Start a firmware update.
SSL Certificate Upload: Saves your own SSL certificate. See chapter "SSL " for the
generation of a certificate in the right format.
Config Import File Upload: Loads a new configuration from a text file. To apply the new
configuration, a "Restart Device" must be executed after the "Upload".
Config File Export: Saves the current configuration in a text file.

Expert Power Control 8021/8025 © 2021 GUDE Systems GmbH
Operating
Saving the configuration should only be carried out in an SSL connection, since it
contains sensitive password information (even if it is encrypted or hashed).
Restart Device: Restarts the device without changing the status of the relays.
Some functions such as a firmware update or changing of the IP-address and
HTTP settings require a restart of the device. A jump to the boot loader or a restart of
the device lead by no means to a change of the relay states.
Restore Fab Settings and Restart Device: Performs a restart and resets the device to
factory default .
Enter Bootloader Mode: Jumps into bootloader mode, where additional settings can be
made with GBL_Conf.exe.
Flush DNS Cache: All entries in the DNS cache are discarded and address resolutions
are requested again.
2.3.2 Configuration Management
The device configuration can be saved and restored in the maintenance area .
The "Config File Export" function can be used to save the current configuration as a
text file. The syntax used in the configuration file corresponds to the commands of the
Telnet console. If the configuration of a device is to be restored from a text file, load
the file with "Upload" and restart the device with "Restart Device".
Saving the configuration should only be carried out in an SSL connection, since it
contains sensitive password information (even if it is encrypted or hashed). For the
same reasons, it is advisable to carefully handle the generated configuration files when
archiving.
Editing the configuration file
It is possible to customize a saved configuration file with a text editor for your own
needs. For example, one scenario would be to use a script language to automate the
creation of many customized versions of a configuration, then equip a large number of
devices with an individualized configuration. Also Upload and restart with CGI com-
mands can be done in scripting languages. With use of the comment sign "#" you can
quickly hide single commands or add personal notes.
If you modify a configuration file manually, it is not always clear which limits are allowed
for parameters. After uploading and restarting, commands with invalid parameters are
ignored. Therefore, the generated configuration includes comments describing the
boundaries of the parameters. Where "range:" refers to a numeric value, and "len:" to a
text parameter. E.g:
email auth set 0 #range: 0..2
