1.7 Safety
1.7.1 Safety notices
Mortal danger - Hazardous voltage
• Electrical equipment operation means that some parts can be under dangerous voltage.
Therefore all parts under voltage must be covered!
• All work on DC connections must be carried out under zero voltage, i.e. DC input not
connected to a source and may only be performed by qualied and informed persons.
Improper actions can cause fatal injury as well as serious material damage.
• Never touch AC cables or AC connectors and terminal directly after unplugging from
mains supply as the danger of electric shock remains!
• Never touch the contacts on the DC input terminal directly after switching o󰀨 the DC
input or disconnecting the source, because there still can be dangerous potential be-
tween negative DC input to PE or positive DC input to PE due to charged X capacitors!
• Always follow 5 safety rules when working with electric devices:
• Disconnect completely
• Secure against reconnection
• Verify that the system is dead
• Carry out earthing and short-circuiting
• Provide protection from adjacent live parts
• The equipment must only be used as intended
• The equipment is only approved for use within the connection limits stated on the product label.
• Do not insert any object, particularly metallic, through the ventilator slots
• Avoid any use of liquids near the equipment. Protect the device from wet, damp and conden-
sation.
• For power supplies and battery chargers: do not connect loads, particularly such with low
resistance, to devices under power; sparking may occur which can cause burns as well as
damage to the equipment and to the user
• For electronic loads: do not connect power sources to equipment under power, sparking may
occur which can cause burns as well as damage to the equipment and to the source.
• ESD regulations must be applied when plugging interface cards or modules into the relative slot
• Interface modules may only be installed or removed after the device is switched o󰀨. It’sn’t
necessary to open the device.
• Do not connect external power sources with reversed polarity to DC input or outputs! The
equipment will be damaged.
• For power supply devices: avoid where possible connecting external power sources to the DC
output, and never those that can generate a higher voltage than the nominal voltage of the device.
• For electronic loads: do not connect a power source to the DC input which can generate a
voltage more than 120% of the nominal input voltage of the load. The equipment isn’t protected
against over voltage and may be irreparably damaged.
• Never insert a network cable which is connected to Ethernet or its components into the mas-
ter-slave socket on the rear side of the device!
• Always congure the various protecting features against overcurrent, overpower etc. for sen-
sitive loads to what the currently used application requires!

EL 9000 B 15U/24U Series
1.9 Construction and function
1.9.1 General description
The electronic DC loads of the EL 9000 B 15U and EL 9000 B 24U series have been designed for industrial high
current and high power demands. Congured as mobile 19” cabinets in either 15 or 24 units of height they allow
for operation in many di󰀨erent situations, such as high current battery or motor tests.
Both series are based on the 7.2 kW models of series EL 9000 B and thus o󰀨er the same set of functions and
control options.
For remote control using a PC or PLC the devices are provided as standard with an USB slot on the rear side of
the master unit, as well as a galvanically isolated analog interface.
Via optional plug-in modules, another digital interface with either Ethernet, RS232, Probus, ProNet, ModBus
TCP, CANopen, CAN or EtherCAT can be added. These enable the devices to be connected to standard industrial
buses simply by changing or adding a small module. The conguration, if necessary at all, is quick and easy. Thus
the electronic load cabinets may, for example, be controlled in connection with other load devices or even other
types of equipment, all via a PC or PLC and using the digital interfaces.
All models are controlled by microprocessors. These enable an exact and fast measurement and display of actual
values.
1.9.2 Block diagram
The block diagram illustrates the main components inside the device and their relationships.
There are digital, microprocessor controlled components (KE, DR, HMI) inside which can be target of rmware
updates. The units are separate power modules, each with their own AC input and DC input. There is a master
unit and up to 5 slave units which don’t feature a control panel (HMI).

EL 9000 B SLAVE
Additional slave units
Some models in this series have a spare slot for one additional slave unit which
can be retrotted by the operator of the cabinet (see „2.3.16. Adding new units“).
The slave unit can be ordered by its article number and retrotted on location. A
patch cable for master-slave bus connection of the additional slave is included.
Retrotting may also require to install further DC bus bars to match the DC bus to
the nal current the system will have. Contact us for details and a proper quote.

1.9.6 The control panel (HMI)
The HMI (Human Machine Interface) consists of a display with touchscreen, two rotary knobs, a pushbutton and
an USB port.
1.9.6.1 Touchscreen display
The graphic touchscreen display is divided into a number of areas. The complete display is touch sensitive and
can be operated by nger or stylus to control the equipment.
In normal operation the left hand side is used to show actual values and set values and the right hand side is used
to display status information:
Actual voltage display
Voltage set value input Status area
Actual current display
Current set value input
Touch area for
rotary knob assignment
Actual power display
Power set value input
Resistance set value input
Actual resistance display Touch areas MENU
and SETTINGS
Touch areas may be enabled or disabled:
Black text or symbol = Enabled Grey text or symbol = Disabled
This applies to all touch areas on the main screen and all menu pages..
• Actual / set values area (left hand side)
In normal operation the DC input values (large numbers) and set values (small numbers) for voltage, current and
power are displayed. The two resistance related values are only displayed in active resistance mode.
When the DC input is switched on, the actual regulation mode, CV, CC, CP or CR is displayed next to the corre-
sponding actual values, as shown in the gure above.
The set values can be adjusted with the rotary knobs next to the display screen or can be entered directly via the
touchscreen. When adjusting with the knobs, pushing the knob will select the digit to be changed. Logically, the
values are increased by clockwise turning and decreased by anti-clockwise turning.
