1.6.1 Symbols and warnings on the device
Decal Explanation
DANGER
RISK OF ELECTRIC
SHOCK
Disconnect all sources of
supply prior to servicing.
!This warning is primarily related to the reconguration of the device on the DC termi-
nal which, for safety reasons, requires to also cut the device from AC (external main
switch). The same applies to disconnection and reconnection of the AC terminal.
Capacitors on DC, stor-
ing voltage! Discharge
for 10 sec then ground
before working.
DANGER
!Even after disconnection of the DC terminal from an external source there can still be
dangerous voltage potential present between the DC terminal poles and/or between
DC and the enclosure. For safety reasons the DC terminal must be short-circuited
after the capacitors have been discharged and it must also be grounded, i. e. con-
nected to PE.
WARNING
ELECTRICAL
HAZARDS
Authorized personnel
only.
!There can always be a voltage potential on metallic, openly touchable parts on
electrical devices, though the voltage level may not be hazardous. Caution is still
advisable, as these potential can still cause mild electrical shocks or sparking.
WARNING
Read and understand the operat-
ing guide before using this device.
Non-adherence of the instructions
in the operating guide can result
in serious injury or death.
!This is valid for any use of the device.

1.7 Safety
1.7.1 Safety notices
Mortal danger - Hazardous voltage
• Electrical equipment operation means that some parts accessible on the outside of the device can be
under high voltage. Therefore all parts under voltage must be covered during operation! This basically
applies to all models.
• The DC terminal is isolated from the AC input and not connected to ground internally. Hence there can
be dangerous potential between the DC poles and PE, for instance caused by a connected external
source application. Due to charged capacitors this could even be true if the DC input or the device
are already switched off.
• Do not insert any object, particularly metallic, through the ventilator slots!
• For every reconguration on the AC or DC terminals, specically those which can have a dangerous
voltage potential, the device must be cut completely from the AC supply (main switch on the distant
end of the AC cable); it doesn’t suce to only use the power switch on the front
• 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
• Avoid any use of liquids near the equipment. Protect the device from wet, damp and condensation.
• Do not connect external power sources with reversed polarity to the DC terminal! The equipment will be
damaged, even when completely powered off.
• Never connect external power sources to the DC terminal that can generate a higher voltage than the
rated voltage of the device!
• Never insert a network cable which is connected to other Ethernet or its components into the master-slave
sockets on the rear side of the device!
• The equipment must only be used as intended
• The equipment is only approved for use within the connection limits stated on the product label.
• ESD regulations must be applied when plugging interface cards or modules into the relative slot
• Interface cards or modules may only be attached or removed after the device is switched off. It’s not
necessary to open the device.
• Always congure the various protecting features against overcurrent, overvoltage etc. for sensitive loads
to what the target application requires!
• Always make sure that the energy recovery can feed back the inverted energy and that it does not switch
to isolated operation. For situations of isolated operation a supervision device (grid protection) has to
be installed
• It’s not allowed to run the device on AC sources such as generators or UPS equipment. It must only be
connected to a power grid!

1.7.5 Alarm signals
The equipment offers various possibilities for signaling alarm conditions, however, not for danger situations. The signals are
optical (via an LED on the control panel) or electronic (status output of the analog interface and digitally readable status bits).
All alarms will cause the device to switch the DC input off. For details about the different alarms refer to section “3.3. Alarm
conditions” .
The meaning of the signals is as follows:
Signal OT
(OverTemperature)
• Overheating of the device
• DC input will be switched off
• Non-critical
Signal OVP
(OverVoltage)
• Overvoltage shutdown of the DC input due to high voltage coming onto the device
• Critical! The device and/or the source could be damaged
Signal OCP
(OverCurrent)
• Shutdown of the DC input due to excess of the preset limit
• Non-critical, protects the source from feeding excessive current
Signal OPP
(OverPower)
• Shutdown of the DC input due to excess of the preset limit
• Non-critical, protects the source from feeding excessive power
Signal PF
(Power Fail)
• DC input shutdown due to AC undervoltage or defect in the AC section
• Critical on overvoltage! AC section could be damaged
Signal MSP
(Master-Slave Pro-
tection)
• DC input shutdown due to communication problems on the master-slave bus
• Non-critical
Signal SF
(Share Bus Fail)
• DC input shutdown due to signal distortion on the share bus
• Non-critical
1.7.6 Functionality test
The operator of the device must decide when to check the device for correct functionality, by whom and how often. The “when“
could either be before every use or after it has been relocated or recongured or perhaps in a dened interval.
Should the set values not be adjustable as instructed below it could simply be due to adjustment limits
interfering. When reaching a limit adjusting value can’t be signaled by the device. In remote control an
invalid value would be rejected, together with an error message.
The test procedure would always be like this:
1. Disconnect all cables (Sense, Share-Bus, analog interface, USB), except for AC.
2. Connect an external DC source that can at least deliver as much current and voltage as the rating of the device under
test (DUT) and set it to 10% UNom voltage of the DUT and full current.
3. Place a suitable ampere meter (shunt, current transducer) in line with or around one of the DC cables.
4. Switch the device on. Using remote control via the front or rear USB port, adjust a current of 10% INom while the voltage
set value is set to 0 and the power set values to maximum. Then switch the DC input on and measure the current with
the ammeter and verify that the adjusted current is owing. Also compare it to the actual current value read via remote
command query.
5. Repeat the same thing at 100% UNom.
6. Should the external DC source be adjustable in current, limit the current to 90% INom of the DUT while setting the voltage
to 102% UNom of the DUT. Add a voltage multimeter on the DC input.
7. On the DUT, adjust 10% UNom and measure with the multimeter on the DC input to verify the adjusted voltage is met.
Also compare it to the actual voltage value read via remote command query.
8. Repeat the same thing at 90% or 100% UNom.
Only if the current and voltage are supplied by the device as adjustable in the range of 0-100% FS, the device can be consid-
ered as fully operational.

1.8 Technical Data
1.8.1 Approved operating conditions
1. 8 .1.1 Ambiance
The allowed ambient temperature range for operation is 0 °C (32 °F) to 50 °C (122 °F). During storage or transport, the allowed
range extends to -20 °C (-4 °F) to 70 °C (158 °F). In case water condensation occurred due to transport, the device must be
acclimatized prior to operation for at least 2 hours, ideally in a place with good air circulation.
The device is intended to be operation in dry rooms. It must not be exposed or operated to extreme dust, high air humidity,
danger of explosion and aggressive chemicals polluting the air. The operating position isn’t arbitrary (see “2.3.3. Installing
the device” ),but in any case it requires a sucient air circulation. The device is allowed to be operated in altitude up to 2000
m (approx. 6,560 ft) above sea level. Technical specications (here: ratings), when given with tolerance, are valid for a unit
warmed up for at least 30 minutes and for an ambient temperature of 23 °C (73 °F). Specications without tolerance are
typical values from an average device.
1.8.1.2 Cooling
Power dissipated inside the device heats up air circulating through the device. With the air-cooled versions a fan at the end
of an air ow channel,in which a cooling block is placed, pulls the air through the device. Entry is on the front, exhaust at the
back. Depending on the internal temperature, the fan speed is automatically regulated up or down, whereas a certain minimum
speed is maintained because some internal components even heat up when the device is idle.
Dust in the air can obstruct the air ow with time, thus it’s important to keep the air ow unimpeded at least outside of the device
be leaving sucient room behind it. Since it’s usually installed inside cabinets, the cabinet doors are required to be meshed.
At the same time, the ambient temperature should be kept at low levels, perhaps by external means such as an air condition.
Should the device heat up internally and the cooling block temperature exceed 80 °C (160 °F), the device will protect itself
from overheating by automatically switching off the power stage. It could then only continue to operate and switch the power
stage on again after cooling down for some time.
For the water-cooled versions, water is the main cooling agent, owing through the internal cooling blocks. The air inside the
almost hermetically body circulates, engaged by fans, to cool the remaining components not sitting on the cooling blocks,
but heat up over time.

1.8.5 Control elements
Figure 1- Control Panel
Overview of the elements on the control panel
For a detailed description see section “1.9.6. The control panel (HMI)”.
(1)
On/Off button
Can be used to switch the DC input on or off during manual operation, while LED “Remote” is off
Pin REM-SB on the analog interface, when set to a logical level which would request to turn DC off,
can block switching DC on by this pushbutton.
(2)
USB port
For quick and easy access to the most important DC input related values when the device isn’t in master-slave mode.
This port has reduced functionality compared to the rear port.
(3) Status indicators (LED)
These six color LEDs show the device status.

1.9 Construction and function
1. 9 .1 General description
The devices in series PUL 10000 6U represent matching models to series ELR 10000 4U. They serve as extension modules,
so called power units, which are intended to build master-slave systems with higher total power. Devices from series ELR
10000 4U, which have a color touch display, can serve as master unit, but all PUL 10000 4U can also serve as master for
other 10000 series electronic loads should the control be solely remote.
For remote control the devices are provided as standard with USB and Ethernet ports on the rear side, as well as a galvani-
cally isolated analog interface. Via optional plug-in interface modules, another digital interface such as for RS232, Probus,
ProNet, ModBus TCP, CAN, CANopen or EtherCAT can be added. These enable the devices to be connected to standard
industrial buses simply by changing or adding a small module.
Alternatively to the air-cooled versions there are also water-cooled version available which are usually congured and offered
in cabinet systems with a complete water cooling distribution inside. For DIY water-cooled systems single units can also be
obtained upon request.

IF-AB
Interface modules
Pluggable and retrottable, digital interface modules for RS232, CANopen, Probus, ProNet,
ModBus TCP, EtherCAT or CAN are available. Details about the interface modules and the pro-
gramming of the device using those interfaces can be found in separate documentation. It’s
usually available on the USB stick, which is included with the device, or as PDF download on the
manufacturers website.
For all models in this series the following software accessories are available:
LICENSE
Software licenses
All devices of this series are shipped with a free remote control software for Windows, called EA
Power Control. Besides free-to-use apps this software has other apps like Multi Control, the Graph
and the Function Generator, which can be unlocked with a purchasable license code. These three
apps are combined under the license “Multi Control”. One license per PC required. There is a single
license and a 5-pack available, also a 14-day trial license which can be obtained upon request.
More information is available in the user manual of this software or on our website.
1.9.5 Options
These options are usually ordered along with the device, as they are permanently built in or precongured during the manu-
facturing process.
POWER RACKS
19“ rack
Racks in various congurations up to 42U as parallel systems are available, or mixed with elec-
tronic load devices to create test systems. Further information ican be found on our website or
obtained upon request
WC
Water cooling
Replaces the standard cooling blocks of the internal power blocks by three interconnected, water
cooled blocks with two taps led out for supply. This option helps to avoid heating up the environ-
ment due to exhausted hot air caused by a certain power dissipation.
As a side effect, this type of cooling also reduces audible noise.
