• All damage caused by non-intended usage is solely the responsibility of the operator.
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!
• 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 output 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 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!

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 electronically (status output of the analog interface) and digitally readable status
bits. All alarms will cause the device to switch off the DC output. 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 output will be switched off
• Non-critical
Signal OVP
(OverVoltage)
• Overvoltage shutdown of the DC output due to excess of the preset limit
• Critical! The device and/or the load could be damaged
Signal OCP
(OverCurrent)
• Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive current consumption
Signal OPP
(OverPower)
• Shutdown of the DC output due to excess of the preset limit
• Non-critical, protects the load from excessive power consumption
Signal PF
(Power Fail)
• DC output shutdown due to AC undervoltage or defect in the AC input
• Critical on overvoltage! AC input circuit could be damaged
Signal MSP
(Master-Slave Pro-
tection)
• DC output shutdown due to communication problems on the master-slave bus
• Non-critical
Signal SF
(Share Bus Fail)
• DC output 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 (DC, Sense, share bus, analog interface, USB), except for AC.
2. Connect a suitable voltage meter to the DC terminal.
3. Switch the device on, adjust a voltage of 10% UNom using remote control via the front or rear USB port while the current
and power set values all should be at maximum. Then switch the DC output on and verify with the multimeter that the
adjusted voltage is available on the DC terminal. Also compare it to the actual voltage value read via remote command
query.
4. Repeat the same thing at 100% UNom.
5. Switch the DC output off and bridge the DC terminal with a cable or copper rails of suitable current capability of at least
INom. If available, put a current measuring device (transducer, current probe).
6. Adjust the current set value to 10% INom, switch the DC output on and measure the current with the external measuring
device, if available, and compare to the actual current measured by the device which can be read via remote query
command or at least compare the read actual current with the set value.
7. Repeat the same thing at 100% INom.
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. 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 DC output. It could then only continue to operate and switch the DC output 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 sealed body circulates, engaged by fans, to cool the remaining components not sitting on the cooling
blocks, but which 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 output 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 output 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 PU 10000 6U represent matching models to series PS 10000 4U or PSI 10000 4U. They serve as exten-
sion modules, so called power units, which are intended to build master-slave systems with higher total power. Devices from
series PSI 10000 4U or PS 10000 4U, which both have a color touch display, can serve as master unit, but all PU 10000 6U
can also serve as master for other 10000 series power supplies 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 standard air-cooled version there are also water-cooled 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.

ModBus TCP, EtherCAT or CAN are available. Details about the interface modules and the
programming 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 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. Post-ordering of cabinet or retrots upon request.
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 on our website or 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 water supply. This option helps to avoid heating
up the environment due to exhausted hot air caused by a certain power dissipation.
As a side effect, this type of cooling also reduces audible noise.

1.9.6 The control panel (HMI)
The HMI (Human Machine Interface) consists of six colored LEDs, a pushbutton and a USB port of type B.
1.9.6.1 Status indicators (LED)
The six colored LEDs on the front indicate various statuses of the device:
LED Color Indicates what when lit?
Power orange / green Orange = device is in boot phase or internal error occurred
Green = device is ready for operation
Remote green Remote control by master-slave or any of the control interfaces is active. In this situation, manual
control with button On/Off is locked.
Error red At least one unacknowledged device alarm is active. The LED signalizes all alarms as listed in
«3.6 Device alarm handling».
CC yellow Constant current regulation (CC) is active. It means, if the LED isn’t lit it indicates either CV, CP
or CR mode. Also see «3.2 Operating modes».
On green DC output is switched on
Off red DC output is switched off
1.9.6.2 Front USB port
The front USB port is easier to access than the one on the rear side and intended for quick setup of DC output related values
and settings. Doing so is only necessary and possible in these two situations:
1. The PU 10000 6U isn’t currently controlled by a master.
2. The PU 10000 6U shall, due to the lack of a suitable PSI 10000 4U or PS 10000 4U master device, be the master of other
PU 10000 6U devices.
Both situations are only secondary, as the primary and normal function of a PU 10000 6U is to be a slave in a master-slave
system where it’s assigned all required settings and values from the master.
When running any of the above listed situations following applies for the front USB port:
• Reduced instruction set for master-slave conguration, set values (U, I, P, R) and protections (OVP,
OCP, OPP). For details about the instruction set see «3.5 Remote control».
• Taking over remote control in order to change the conguration is only possible while the unit isn’t
online with the master, which either requires to temporarily deactivate master-slave on the master
or to switch the master off.
• The front USB has no priority over any other remote control interface
1.9.6.3 Pushbutton “On / O”
This button can be used to switch the DC output on or off during manual control, i. e. the device isn’t in remote
control by a master or via any of the USB ports (LED “Remote” = off), but only if the DC output isn’t blocked by pin
REM-SB (analog interface).
Once pushed to switch the DC output on, the device would regulate it to the last values it has stored. Since all the
DC output related values aren’t displayed, operating that button has to be done with caution.
The button can furthermore be used to quickly and without the need of a PC turn the device into slave mode. This is
done by pressing and holding the button for at least 10 seconds. The switchover into mode “Slave” is conrmed by
the LED “Error” lighting up, indicated an MSP alarm (see section «3.6 Device alarm handling» for more information
about this alarm) which is normal for not yet initialized slave.
